When I was a young C.B.er, the Star Duster was my antenna.
This antenna served me well.
Lovely!
I have a old german sirtel s 2000 and polished them in moment and will build it after 30 years on my house roof again. Hope i can hear everybody again, it was a very good antenna in w-german quality. 73 from germany. Right cable lengh for RG213 are 18,35 m or 22 m that is right for 26,975 Mhz ?
Thanks Callum, just getting back into 11 &10 meter radio now I am retired, I made a 1/4 wave vertical last night, took around 15 minutes and strung it up in a tree, the radial was also strung up so the antenna has a L shape, SWR 1.2:1, amazing indeed. I have learned so much about antennas the one thing is that you don't need to spend big $$$.
Nice work!
Since the CB service was created I'll wager that more money has been spent on this slice of the spectrum than any other. The pre-1970 magazines always had build-it-yourself projects in them.
I'm been studying and working on 10 and 11 meter antennas for 45 years. Some antenna theory has actually changed in those years. The Starduster was sold as a half wave. The coaxial feed line goes inside the mast pipe, for additional shielding / isolation from the antenna. The downside is the radiator is not grounded. The small radials are on the center of the quarter wave radiator. Some speculate that it is to increase frequency range, while some believe it is to raise the high current point on the antenna to reduce ground loss and increase gain. In a similar, "modified quarter wave" the radials are angled down to a point to increase the impedance to 50 ohms. The Starduster radials are angled down even more and possibly the small center radiator radials somehow decrease the impedance to match the feed line with the large radials angled so far down. The Starduster antenna design does work really well, especially considering its smallish size.
Very interesting Jim.. Thanks.
@@DXCommanderHQ Back in to late 70s I used a Starduster for 11m and 10m... After I put up a multi-band quad, I shortened the elements to optimize it for dedicated 29-29.7 FM use. The radials were sloped down more than 45 degrees, perhaps 60 degrees, and the vertical/radial lengths were asymmetric. I tweaked the asymmetry slightly when I trimmed it for 29FM, increasing the asymmetry - making it more-off-center-fed - seemed to tilt the pattern slightly towards the horizon. Also, someone diddled around with a coax matching section, 75-ohm I presume, and was able to get a "perfect" 50-Ohm match on theirs.
Same here !
The lower angle achieves a slightly higher gain. Isolation from a conductive mast is preferable for a cleaner pattern. A decent coaxial ferrite choke should also be employed for CMC, and you may wish to take care of static build up by grounding the shield of the coax (from memory, I think a 1/4 wave down from feedpoint). I have built such an antenna with 8 ground radials, and it was a great performer.
I’ll tell ya not for nothing but I talk to a few guys running them on channel 6 and there is a guy on 11 also and they just boom into my phone radio and I know there not running huge watts and I know they’re not lying because that thing would fry to much more then 2,000 watts and that’s not bein longwinded
I had one of those Starduster Ground planes from the 70's and I loved it! Had it at 40' on a pushup pole and we used it all over our FARM.
Out of all the antennas I had back in the 80s the starduster was the one I always went back to , I was actually thinking of building one so glad to see this video thx Rick

Thanks for this, I have found it interesting. Personally though I'm more interested in how an aerial would perform at roof height (where most of us mortals would place it). Before anyone shouts at me I do realise that height really does matter but I am a council estate dwelling realist! Please keep the vids coming DXC - I really find them educational AND entertaining!!
OK, I will discuss this soon..
Antron A-99 with the 5/8 wave "power up" top section - add the ground plane kit, - best ever 10/11m I've ever used - had a great qso with Bob McLeod in the Falklands only using 10w on 10m using it.
Lovely!
Me too
Hi guy's, I use a high gain 36' J-pole tuned to 27mhz made from 1/2'' copper tubing hanging from rope inside a tree and i can work anywhere i want from 5 to 100 watts! I have talked over 50 miles away on 2 watts as a test base to base no BS!

I have a Sirio M-400 Starduster, I run on 10meters, looks identical to the one pictured. I have it mounted with the feedpoint at about 30ft. It is an awesome antenna. I have worked a bunch of DX on that piece of kit. It is wide-banded and is fairly flat across 10 and 11 meters according to my Rig Expert. I believe the bit at the top is a capacity hat. I say build the darn thing Cal!!!
Will do John!!

@@DXCommanderHQ the 3 things sticking out on the top rod is called a capacitance hat.
Thanks for doubling my workload, because now I'll have to build one for 10/11 and one for 6.😱 Since Monday I've been working USB 10M on a new Anytone AT5555 PLUS/N feeding a homebrew T2LT/end fed RG58 coax dipole with 16 turn air choke hung in the redwood outside my bedroom window. I've made 30+ contacts 1,500-2800+ miles. Most signal reports 5/7-5/9; some 5/4-5/5. I'm gut hooked now and 10 is opening. This weekend with Winter Field Day working through the pileups gave me a lot of confidence in this trucker's rig that's my base and portable. Anytone had a long time to improve this model, but the "N" makes it worth using. The NR circuit they added to the V3 simply makes the difference in being able to listen without fatigue. But no, it's not one of the big three; then again it was only $200 with a $9 antenna. I learn from your videos more than hundreds of others, thanks mate.

Wow. Fabulous!
You have made my day. Callum this is something I've always wanted you to build as I would to get rid of my silver rod plus I would like something homemade myself. I will definitely buy you a beer and buy the parts to construct this.
Go for it!
You are right. CB antennae can be used with 10/12 m with physical tuning or with a manual or auto impedence matcher.

Ive been using a homebuilt CB antenna for the last 35+ years. I have no interest in DXing but I happily talk to the locals (15-20 miles away) without issue.
Its a centre fed dipole. A length of 2.5 twin & earth wire 18ft long left over from the house rewire.
Split the wire from its gray insulation. The wire is wound onto 2, 10ft pieces of PVC pipe like 2 firesticks.
So its 18ft driver and 18ft ground plane in a short package.
I did have a silver rod at one point... It snapped at the coil during a moderate wind, hence I built my own at the ripe old age of 12 years old
Nice one!!

The Starduster stations always performed well.
I was using an Avanti Astro Plane with great results.
This design resembles the Civil Defense antennas designed by K1GOI at MIT Lincoln Labs in the late 1950's. These 6m and 10m 'starduster' like antennas could be found on most schools and fire stations up thru the 1990's

Those pieces at the top are a capacitance hat. Its actually quite useful for antennas at this length. Remember sir, a proper gentleman is never fully dressed without his hat.
Do I fancy you building it? Of course, thats always great fun. Of course I would love to see you drag an old CB out and see what it does on 27.385. I think that would be an absolute hoot.
I have a CB... Hang on!
@@DXCommanderHQ That's a big 10-4.
@@DXCommanderHQ I would certainly hope you have one. Hell, most of the hams I know have their radios geared to cover 11 meters if they don't still have the old CB around. We don't like to talk about that though.

I have had the m400 up before worked great it was at 45 feet replaced it with the 2016 5/8 on 10 meter and turns out it's all most a perfect match on 20 meter with about 1.6 swr talk all over the world on it from south east US it is amazing how well it works
Wow
The starduster reminds me of the thunder pole antennas years ago I had the thunderpole3 this had a small loading coil in the center of the main element.I actually changed the top element and used a mobile modulator type antenna it worked really good.have a great day all and all the best to you and your families.
I think the thunderpole 3 was better than the thunderpole 2. Another antenna from the same period which used a center loaded top that worked well was the delta dx with the coax running down at an angle making it look like a boat sail.
Thunderpole did one without the little legs on the radiator element the thunderpole 2 had a coil on it , I had one but I unscrewed mine and replaced it with a 9ft mobile whip , worked fantastic
as i just got back into cb i used a 108 aluminum element for center, then used 3 108 wires for lower elements adding string to use as guidewires also. was exact same look as starduster.
worked great! but last week i bought a 5/8 groundplane and new antenna was much better.
the difference in 9 foot main element and 22 foot main element was substantial.
love to see one working Callum, another enjoyable video your head is full of ideas. keep up the good work.

Hi a GREAT ant I use to run American antenna M-400 on a mast of 72 ft and altetude of +/- 4200 ft and could normaly run 20-250 miles and work the world with it can say must be 1 of the best I ever had,
Thank you,

I'm sure! Sounds incredible. I think you could probably do that with a 6 inch nail! :)
Thanks for the info. Very educational. Hope to here you on skip in Alabama.
the little thing in the middle of the top element broadens its band width. Had one many years ago. running without it raised the swr on the upper and lower CB channels. With it, and it was wider band width.
OK!

I "/think/" that little "thingy" near the top of the antenna might have been an attempt at a "capacitance hat" as I've seen a similar "thingy" on a Hustler 6 BTV multiband vertical ground plane that I had years ago.

Look at the 1985 Radio Shack catalog on page 73. The Crossbow 21-968 1/4 wave antenna worked great. I still have it in my barn.
When I was first licensed, my dad had one of the Starduster antennas that he used on CB. I borrowed it from him and found it worked great on 10 as well as good enough to get me on the air on 2 meters. With a tuner, it was also effective on 15. WD5DHK Ray
Haha.. I'm sure with a tuner it'll work just fine!

Hello callum, best one I've used is a forward gainer. 2 element horizontal dipole on rotator. Wow what an aerial.
Vertical wise a home brew gain master coming out 3m above a 100FT tree.
Thanks for sharing cheers
Nice one!
There is a difference. Some of the big electrical 5/8 mobile antennas like the Sirio don't do as well for local contacts as simpler cheaper antennas. Seems to be the angle of radiation that's the issue. I think that three pointed thing in the middle of that aerial would increase the bandwidth a bit. You could try it with, and without, and see if it makes any difference. If you thicken an element it tends to give better bandwidth (at VHF anyway, I made dipoles out of aluminium foil to test this once).
You nailed it. They just slid that thing up, (or down,) until the antenna had a good SWR match across all 40 channels.
took my starduster apart and put back together up top of a 65' pine tree. stuck 15 foot out of top. live in a great location *(very high area) I was on 300'ish watts and was a beast. (back in the 90's)
Goodness, you would have been loud! :)
That very antenna right there is what I am using here at my location. She will handle quiet a lot of power too! She works really well for me.

The original version of this antenna was called the Thunderpole. I think this was how the company of that name got started. The reason it came about was because of the legal restrictions on CB base antennas at the time. The maximum radiating element length was 1.5m so half wave verticals weren't allowed. The Thunderpole had a 1.5m base loaded top section. This type of vertical dipole arrangement was about as good as you could get if you were staying within the law. Although I had a neighbour with a half wave vertical that had a fake loading coil 1.5m from the top and the length below that disguised as a support pole. And back in those days you had to switch to low power if you used an outside antenna.
Fascinating!

Good evening Callum what a fun video. Back in my CB days in the 70s I had one of those star duster‘s antennas. I am really amazed on how expensive they are, I think I bought mine for around 25 pounds or $30 US. Believe it or not back then I have fun on the radio. Thank you for the video really enjoyed a lot.

Very cool Steve. It's gonne be a fun build.. Probably September..
As a teenager around 1977, I had the original Starduster by Antenna Specialists and it worked fantastic. It stayed up for many years after I moved out and became a young man in my 30's before my parents took it down form their home.
The only other Antenna that I used back in the 1980s in the no man's land between 10 & 11 meters was the The infamous Hy-Gain Super Penetrator 500. That antenna was awesome for dx. I recall a huge club in the UK that called themselves The Jolly Rodgers Club. Those days were awesome.

Nice work on this, Callum. I have a Solarcon A-99 and if there was only ONE antenna I could have for 10, 12, and 15 meters, believe it or not, it is the Solarcon. It gives around a 1.5:1 SWR on all three of those bands. Granted....it uses the coax as a counterpoise....but it does a bang-up job. I frequently get signal reports on FT8 here in Florida that is +1, 2, 5, or 10 DB over S9. Many hams are very biased against these kind of antennas because they are marketed as CB antennas...but who cares what they call them? As long as they work. 73 de Scott, W1AL
I had a Starduster years ago after college and found a shortfall no one speaks about. Directivity due to the down radials for the ground plane. I found by increasing the ground radials to more of a cone shape greatly helped reduce the directivity with a minor need to retune the vertical element. I found that a Discone design seemed to be the best design I could use but it sure was weird looking on the tower. I should mention I am a retired Radio/Television Engineer.
Hello Robert. Now before I asnwer, you need to appreciate that your comment to mine will be buried, so I apologise in advance if I don't respond to you. However, I would like to understand! Maybe I can ask you to drop me an email because I would like to understand what you mean about "directivity". So for instance, was the directivity in the horizontal plane - or did you produce gains and nulls..? Anyway, an email would be great thanks. qrz at m0mcx co uk.
Robert, if I use 4 radials in my Exnec model the directivity problem in the Azimuth plot you note goes away, but the best gain goes down a little too using four radials. I doubt anyone would ever notice such small differences, however.
@@eddiemarconi3420 That is to be expected as I noticed on my old Starduster. I never tried readjusting the length to bring it into better resonance due to the more complete ground plane. With my experience working on AM Broadcast Band antennas we always installed as many ground radials as we could and then adjusted the tower lengths to optimize the radiated power. Laborious work but worth it when powering the antennas with 15 to 30 Kilowatts.

now you are taking me back you are right again in pricing a great way of getting more stick cb on it
Right on
3 small radials mid way on driven element are capacitance hat, and adding it will help lower the signal takeoff angle.
Honestly. I just found this video at 2007 on Thursday 26th Jan 2023. I thought of and built this antenna on around the 12th of this month....for 70 Mhz...4Mtrs. I put it at about 10' above concrete and vswr was 1:1.2 on 70.425. Unfortunately I've been sick for a couple of weeks so it's yet to be tested at about 20'. I didn't need some clever program, just a tape measure and a pipe cutter...for the alluminium. However your graph is showing me what to expect (sort of) of the radiated pattern. I remember the old CB antennas of this design (there was a legal one for CB27/81 called a 'thunderpole'.). They worked quite well and yes, basically they're a 1/2 wave dipole with the bottom element split into 3 GP's. I'll compare it to a homebrew J pole and then possibly modify it for a 3/4 wave radiator...for the fun of it and thats the reason why I did the RAE in 1984. Cheers and 73.

I use CB (11 meters) for two totally different purposes. I have AM only CBs in my car and truck, with fairly small mobile antennas, running about 35-40 watts. These are for short distance local line of sight communication only. In the U.S., where I am, almost nobody has a CB in their personal vehicle. BUT. Almost ALL truck drivers do. So if you are driving on the highway, you will always be within range of someone you can communicate with very clearly. But just because they can hear you (if their radio is on) that doesn't mean they will talk to you. You have to be able to speak their language. Driving a truck is a very lonely job, and truck drivers actually like to have someone to talk to, IF it is the RIGHT someone. I just happen to be one of those types.
I have an 11 meter SSB setup at home, with some extra channels, running 100-200 watts. That's clean RF, NOT splatter. I'm using my own homemade tube amp. I also have a whopper of an antenna in the back yard. I built it, but I have to admit I didn't design it. I did exactly what you are talking about. I copied the design from the '70s. It's a copy of what was called a Moonraker IV back in the day. It's a 4 element cubical quad beam, and it's so big and heavy that I had to use a Rohn tower designed for amateur radio antennas to put it up. I use it with a rotator. I have made contacts all over the world with this setup, though I seem to do better with Asia and the South Pacific, especially Australia and New Zealand.
Oh, by the way, that little thing on top of most older three element ground planes is called a "top hat". Its usefulness is debatable. It slightly changes the antennas impedance, which may or may not increase its bandwidth, depending on a lot of other variables. It can also increase the antennas capacitance, but again that depends on a lot of other things. Way back in the mid '70s, I had a 5/8 wave ground plane that had a top hat. It worked very well, but whether the top hat had anything to do with its performance is unknown. It had no measurable SWR across the entire 11 meter band. I used it on AM only. I didn't have an SSB radio back then.

There was one more unique design for the CB craze of the 1970s and 80s other than the Starduster. A company called Avanti made an omni called the Astroplane and a 3 element vertical beam called the Astrobeam. Each had a strange loop/hoop...something you may want to investigate or tinker with some time? As I recall, the Astroplane had a wide bandwidth similar to the Starduster. The wealthy of the time ran beams called Moonrakers 4, 6 and 8 element versions. Also there was the 2 element PDL-II that preformed well.
Yes, I had the PDL2.
If you build it, they will come!! Yes Cal, I would love to see this build.

I use a high gain 34' J-pole tuned to 27mhz made from 1/2'' copper tubing hanging from rope inside a tree and i can work anywhere i want from 5 to 100 watts! I have talked over 50 miles away on 2 watts as a test base to base no BS!
Hanging from a tree. Absolutely perfect!

i bought a new starduster to use my my new export yaesu gt474gx in 1989. put the antenna on the chimney and talked all over the world on it. i was given an avanti astroplane in the 80s and eventually binned it because i could'nt figure out it worked and why the swr was high and i could'nt get it down. years later i read they function as some sort of DC short !
Ah!
Excelent. I would love to see a rebirth of CB in the states. Maybe this antenna would be the boost CB needs. A duel band CB / 10m or would probubly be a good seller as you could get both Amature radio and CB band sales.
Kinda hard when these blowers aka cell phones are so popular. Still seeing aluminum in the air in my city, just a small handful still operating.
@@fridayjoefriday the CB band is manely full of people running higher than legal power and trying to talk to the world. Very few local people using CB and even fewer OTR truck drivers. Hams all start from somewhere.
@@brentchristians9888 I still use CB to talk with local peeps, circa 5-7 mile radius( most are licenced) but the conversation is easy like a pub lock in as opposed to a night at the Opera.
Thier is a uhf CB service in u.s. called GMRS and it uses repeater's up to 50 watts gaining traction as we speak
@@Cardassiaprime: 😆🤣!!
Built one and used it for 15 years + seemed better with 4 radials and a slight difference on the feed point
The factory one was fed through the bracket that retains the radials
I fed mine on the side and 16M above ground wit consistant good results😁
Would love to see you model the omni quad
Built one for 2M and frankly i am impressed with the results so far
Love the content
Thank you for the excellent videos keep them coming👍
Quad.. Yes - and a good match to 50 ohms too! I'll maybe not build one, bit having experience of a PDL2 back in the old days, I might model one and see what it does!
@@DXCommanderHQ
The omni quad is not to be confused with the cubicle quad
Found the design on the ve3sqb site, i do not see it there anymore but it is still available on the way back machine, some ridiculous gain figures are claimed, how ever it has serious band width and from monitoring satelites it does seem to have a very low radiation angle
If the program is difficult to find i can zip it and try to mail it👍
I'm relatively new to your channel having recently had a renewed interest in CB radio. I would definitely be keen to see you build the antenna. Cheers.
Welcome aboard! We will build this, either end August - or mid-September. Hang on! :)
Hey! Thanks for joining in.. If you have time, join us on the full-build and test Premiere? th-cam.com/video/V8Qq4-0_TjQ/w-d-xo.html
I knew this design in the early 80’s as a “Thunderpole”. They were good but I nick named it the drunken pole coz looking the number of them mounted on chimneys were “legless” on one of the three, 😂
Oh yes!
The things at the top are supposed to be a capacitance hat. It's a quarter wave with steeply angled radials. The design is in an old version of the ARRL. It's not a dipole since "di" means two and it has four elements.
Clever!

we had this antenna back in the 80's when i was a kid, a simple fiberglas construction with no bracing and no smaal antennas at the top, and i think a 15 w radio for a while, dont remember the brand but a big metal box that loocked like wood with a v shaped front , it for sure knocked out the tv while talking. it was a pretty common setup, as theese radios where used in fishing boats until the VHF came along. this antenna may even still exist at my parents house somwhere. how does a cb compare in range to a VHF no skip added.
Sirio 2016 is my weapon of choice. Works 10, 11, 12 and 20m.
OK, so I built this one in the end.. If you have time, join us on the full-build and test Premiere? th-cam.com/video/V8Qq4-0_TjQ/w-d-xo.html
I started my radio endeavor with cb radio in the 90s and it has led me to ham radio but back in the day the best vertical antenna was a maco 5/8 wave made a lot of distant contacts with them 73 your friend Kd9dle

Hi cal. I had one of those antennas in my early cb days. Think it was called a skylab back then. Worked really well and lots better then the thunderpoles.
Skylab.. Yes, I think it was that ..!

I’ve had best results with half wave antennas on 11 mtrs , and the cheap to construct T2LT, ( strapped to a fibreglass,Fishing Pole ) , works as good as any other half wave , I’ve ever tried , haven’t tried every half wave , but most , cheers Shane
I know this antenna as the "skylab". It wasn't rather populair as far as i know. It would be interesting to see you build and test it.

My personal favorite "ultimate" tenna setup for 8-11m is a Maco v58 on a pneumatic mast for tx and a 4ft square mag loop with 2" dia elements for rx.
Why you ask? The 5/8 mako has 5db worth of omni gain for fantastic local and its also a great skipper especially with a pneumatic mast to adjust the skip angle in real time.
And when it comes to pulling signals out of the mud its hard to beat a properly positioned mag loop with a sensitive pre amp or receive circuit.
The day time noise floor on 11m is brutal enough then to factor in all the modern day man made noise is a perfect recipe for loss of interest.
Mag Loop - or you might also want to try a VERY long wire. I was pulling signals out of thin air with my very long wire experiement. I couldn't believe it..!
Would love to see this happening! Another Version for 15m would be interesting too!
Oh yes!

For me, the Avanti Astro-plane was the Ultimate CB vertical antenna. I couldn't afford one initially and still am using the over 40 years old Hy-gain Penetrator 5/8 wave. I eventually had a Moonraker 6 setup. But a storm took it years ago. Been a Ham for a while, but still like to fool with 11m too.
Nothing like fooling about with radio!
I would love to see this built & tested Callum. 👍

From my experience, the sparkly purple finger nail rarely effects the resonant frequency of what’s is basically a 1/4 ground plane. I found a full set of red nails is useful for working Dx from the /P location
Good point!
Back in my day we called them a Thunderpole.
OK!
yeah then the thunderpole 2 and 3 came out i cant remember what difference the 2 had but i do remember the 3 had a coil in the middle of the driven element
OK, so I built this one in the end.. If you have time, join us on the full-build and test Premiere? th-cam.com/video/V8Qq4-0_TjQ/w-d-xo.html
@@DXCommanderHQ I'll be there as always Callum, looking forward to it.
The object in the driven element is there to very slightly lower the radiation (take off) angle. It would also have a slight capacity hat effect, but not much, due to its size and placement.
I didn't need it: If you have time, join us on the full-build and test Premiere? th-cam.com/video/V8Qq4-0_TjQ/w-d-xo.html
I would like to see you make this Callum and see how it performs ,
My mate had a original Starduster back in the naughty 40 days of AM and used to get out well ,
I never had one. I'm quite excited about this!
@@DXCommanderHQ His was only about 15 foot of the ground to the base and he used to do very well on it compared to my Hy-gain silver rod which was about 25 ft to the base ,
I'm looking forwards to your make 😀

With this design he lateral lobes overlap nicely and aim solid at a low angle, without warming clouds.
And with an anti-rotational flux mat with reverse sine dB loss. And that's how I read your comment :)
An interest experiment Callum. Most of the 11m antennas on the market are 5/8 wave so it will be interesting to see how this performs. It does have a hight advantage though. Looking forward to the next video on this.
Yes.. Mike M0MSN made me a wire GainMaster. That's 5/8th so if I can find a couple of ground wave stations, we can perhaps do some 10-mile line-of sight checks too..
OK John... Sorted! If you have time, join us on the full-build and test Premiere? th-cam.com/video/V8Qq4-0_TjQ/w-d-xo.html
LOL..."It means you can charge more." Best line ever.
I made a tuned CB 1/4 wave antenna using solid 10 gauge house wire and held up by a rope 40 feet up between 2 trees and 4 radials at 35 degrees its been my main antenna for 7 years now.

Can't believe I've missed this one, for some reason my subscription wasn't there. I believe they were called a thunderpole originally. If I remember correctly those little legs were to help with capacitance 🤷🏻♂️
When I ran CB radio, I run 5/8! 10.5 meters high. Coax was tuned with a 50 ohm dummy load. The radials 90 degrees to the mast. The antenna on the ground was tuned antenna wire 4 positions going out 22 meters. Then the radials were tuned on the mast with the antenna with antenna still hooked the base of the mast. I was getting about 100 km a night straight shot and the day all around the world at 4 watts!
Straight shot. Lovely.

@@DXCommanderHQ will do, Boss!!
The best antenna I have ever built for local work on CB was a J Pole. Although, I have built many Quarter Wave Droopys, and they have their advantages. I friend of mine 50km away has a 5/8 gp and a quarter wave. There is a lot of terrain between us, up to 1000m. When he switches to his quarter wave, he jumps up as much as 2 S points (by my cb base meter) compared to the 5/8. This I believe because of the higher take of point, the 5/8 runs into the terrain. This can also be advantageous for skip, 'drop zones', if you will.
Well. I remember Roly making a DX contact on 28 MHz with a 6-inch nail..! When conditions are in, it just works :)
@@DXCommanderHQ yes, I've spoken to QLD on the Hill's Hoist (that's a clothes line) and the top barb of the our farm fence. But still, 12 watts to Ireland, almost 10,000 miles on a vertical only 6 or 7 meters up with a strong signal... not bad. You know we don't get those conditions every day.
I was a RTO (radio telephone operator) in 3rd Ranger Battalion back in the 90's when my unit went to Jungle Warfare School in Pamama. As part of the training, I built a military field expedient jungle antenna called a 29er2 jungle antenna. I had a pocket fisherman that I carried in my ruck and would use it to throw a washer over a high tree branch in the jungle canopy. Coms are a big challenge in the jungle and was able to make coms with the HQ about 7 clicks (km) away. We were of course in the military bands in the 10 m range. 30s MHz. We were taught to get three equal size bamboo or sticks. We measured them by spreading our arms out and estimating that distance. Then we used speaker wire and 550 paracord to make the radial wires and the radiated wire. Those were all measured the same way from hand to hand outstretched from each other like wingspan. We used additional speaker wire to connect the main beam and the radials to the radio. Anyway, this is basically the same thing as the military's field expedient 29er2 jungle antenna that was used in Vietnam. I have been planning to make two versions for 20m and 40 m bands. I think you would have to make the radials and main beam 15 feet and 30 feet. Do you have any idea whether or not this would work?
The paracord was used to tie the sticks together in a triangle and as the way to tie the ends of the radials to the corners of the triangle. It was also used to hang the antenna high up in the tree. I used the fishing pole to throw and large washer up in a tree and let it come down to the ground. Then connect that to the 550 cord and pull it up over the branch. Connect the top of the radiated main center beam to that and pull the antenna up as far as you could to clear as much vegetation as possible.
I do have a fiberglass pole like you are discussing that I could use. But one of the main benefits of the 29er2 military version was its relative light weight since we were loaded with 60 to 90 lb rucks and humping 12 to 20 miles a day through muddy and hilly terrain.
I have a couple hundred feet of speaker wire that I know will work, but I also have some electric fence 17 gauge aluminum wire. I was wondering if you have any idea whether electric fence wire is any good for antenna making?
OK, I am not quite sure if this was a ground mounted yago maybe? Google has no trace of the 29er2 - I'm so sorry I don't know.
Wire type: ANything works old friend, just make one :)
I've been running a MACO 5000 5/8 on the main shack and a 1/2 wave Tram 1498 on the main house. The biggest difference I've seen between the two seems to be the fact the MACO has less bandwith, and only occasionally better performance. Both do great in local LOS testing, both have made South America on skywave with raving reports with 200 watts, 8,000+ miles out.
I think your point is very good. As long as you aren't using a compromise antenna, they will all work well. Height, terrain, nearby objects, far field, can all have more impact than actual antenna choice per se.
The inferiority of my 108" whip on my big 20 foot long Lincoln car, and the poorer performance of my Hustler BTV6 on 10 meters, is better explained by the difference in height to my bigger antennas, more than the 1/4 wave vs. 1/2 wave vs. 5/8th wave argument.
I think you make perfect points!

Would be great to see it built. I’ve never had or used one but had heard good reports. Had been told the mini radial kit on the driven element was a capacitance hat…I’d always had Shakespeare Big Stick until I built one of Mikes 5/8 Gainmasters.
Great performance 24.5-29.5 MHz.

The Starduster if I remember was also used a lot in Lofts and on Bedroom floors, for the people who were not allowed an external aerial by the landlord, I remember quite a few who had them outside were accused of using a burner.
Its like the difference between a Avanti Sigma 4 & Sigma 2, Personally I always favoured the Sigma 2 because of the Radials, where as the Sigma 4 was more of a J Pole, not that J Poles dont work well, I use one now on 11m band even now.
Yeah OK!
Callum, please build us a Starduster wire antenna.
I think my old ST'r was the best CB antenna I ever had, and it was close to 50' feet to the feed point and well guyed.
In answer to Robert Quance noted below.
"Robert, if I use 4 radials in my Exnec model the directivity problem in the Azimuth plot you note goes away, but the best gain goes down a little too using four radials. I doubt anyone would ever notice such small differences, however."
