I have the 5/8 wave Sirio standard tunable 10/11 meter ground plane. This one has an adjustable top hat for tuning and 3 long radials. They are around $100. I'm using this until I get my hex beam But it's a really good antenna. I've made contacts all over the world with it on 10 meters with only 200watts. Studying for my general ticket and will get the hex beam up by the time I'm legal for all the other bands.
I have an original Penetrator 500 I bought back in the early 80's that I just took off my roof and put in the shed. It was a great antenna back in the day.
I had a Sigma 4 in the UK, absolutely massive aerial...worked no better than a cheap 5/8wave vertical with no ground planes. I got a far better range on the 5/8 wave silver road on a 10ft pole hammered in to the garden compared with a Sigma 4 on a 20ft pole on a house. Both fed with RG58U in those days as we didn't know any better. The silver rod was hit by lightning and the top 3 sections vanished, plus there was a strong ozone smell on the grass.
I have had 2 of the Megarang 827 antennas myself, 2 of my best antennas. Tip replace the screws at the top parts with clamps. Screws wear out the aluminum by moving the antenna, it then sinks 1,2,3 cm until a part collapses or slides in.
The metal roof certainly doing the heavy lifting giving the vertical antenna a really good reflection. Being elevated certainly helps as well because as we all know "height is might". The combination of the two probably makes this antenna a stellar performer.
i saw my first 30 years ago when i had the CTE Spectrum, which was a copy back then on the Sirio 2012. i've had 827 thought for nearly 30 years myself..
Thanks for the video. I am building a repeater on 29.64 in Houston, Texas. What is the usual separation distance between the receiver and transmitter? I have two sites that are about 6 miles apart. 73, Glenn WB5TUF
Awesome Glenn! 6 miles should be more than enough. Here is an interesting read on horizontal and vertical separation - www.repeater-builder.com/antenna/separation.html I aim for about 100dB of isolation.
I've had an 827 up for 14 years - it was tuned to 11m for years but SWR crept up eventually - cause was on the top 3 sections, the screw holes elongated an inch on the 3rd section where it joins to the 4th section, after taking it down for repair, I cut slits in the ends and used Jubilee Clips/Hose Clips and aluminium grease, put it back together and re-tuned it to 10m - with the rig internal tuner on just the mini 8 coax, it matches up on 6, 11, 12, 15, 17, 20 & 30m - some times it will match on 40 and sometimes it wont? - it's also usable on 2m. Mines just 9 feet off the ground, in the back garden surrounded by houses but like 30 or more yards North, 60 yards East & 200+ West from the antenna and just 10 yards space towards the South, and on FT4/8 I've hit Australia, Argentina/South America, Falkland Islands and as far west as California from the UK to name a few, I think it's a superb antenna. It was £119 when I bought it and even today it's around the same price in the UK :)
Haden, I can't speak personally about that antenna, but I know two people that have used them with superb results, but both have suffered broken radials on several occasions and that is with the ring. Don't know if it was fatigue or the cocky's but I have heard the radials vibrate in wind. What I can say is, I bought two Sirio 2016 antennas like you at great expense and even more ridiculous freight charges but are the best 10/11 vertical I've tried hands down. I do have a 4 element Sirio Yagi to go up on me mast when I get round to finishing it and can't wait to try it coz I've never experienced a Yagi yet.
What a cool project. How exciting! Hope we'll be able to hear it in the Eastern US. I worked a Japanese station today from my vehicle today on 10m SSB barefoot (gray line... So maybe!)
According to the manufacturer’s specifications, the antenna can be tuned up to 28.4 Mhz. Did you have to modify the top end of the antenna to tune it to 29.680 Mhz.
Hi there, i had a Sirio 827 in the past and i got another one this year, its a very good antenna i am vey happy to have it again. on the Dx contacts i did last week 11.700 km, only with 100w, contact to indonesia. 73 from Portugal.
I used a Solaron vertical with mixed results, before I learned about radials, sadly it got broken before I could give it a proper ground plane and play with it.
I put an older version of that antenna up in 1987 and half of it is still there. The top half eventually fell off after more than 25 years of punishment. The Italian companies make their antennas a lot better than they do their amplifiers.
@@HamRadioDXI have a constant s2-s3 . It's not a classic static sound . Seems like there is noise inside but doesn't sound like a proper noise . I have run my radio on battery and still the same. So the antenna is grabbing something out there . Perhaps electricity pylons that have outdated equipment and need to be replaced. Should I change antenna polarization or try a common mode choke ? Jimmy SY1DAL
Sirio makes a pretty good antenna.. I have the Sirio 2016, its very similar to the 827, only it has 16 short radials rather than 8 longer ones. Ive worked 37 Countries just on 10m with it. Bonus! It tunes up on 11/12/15 with a tuner. Works really good on those bands WITH a TUNER.
'it tunes up' ?? no it doesn't, it is tuned for 11mtrs, and once set it stays tuned for 11mtrs. your tuner fools you into think the ATU pixies have gone and tuned it for other bands. hand your licence back, you don't deserve it.
@@CBRadioWayBack10-4 No, I tuned mine strictly for 10 meters. I know using my tuner is a compromise, but the best antenna is the one you have. So I use what I have with a tuner. Go away kid, your taking up my oxygen.
Hey Hayden, yeah probably unlikely but if you're ever in the Wollongong area I'll give you a Opek HCS-100 CB base antenna, new never been used. I had plans for it before but won't be needing it anymore.
Hayden, your antenna looks great! It sure would be neat if I could hit it from northern Minnesota, US... what were the frequencies? FM 29.680 input/29.6 output did I see at the end?
I see your 10 meter repeater is on 29.68 MHz, which is a frequency I have sometimes keyed up here, when the band is open lately. I have on numerous occasions used 29.65 repeater HB3HD in Switzerland from here in the state of New Hampshire. A couple of weeks ago I reached OD5TX in Lebanon and other times, stations in Switzerland. 73 de W2CH Ray, NH 😊
If there was a supplier in Australia that had the stuff at anywhere NEAR a fair price, I would use SS-30 Jet Lube on the elements instead of the carbon grease. But, I only found one supplier, and they wanted almost $90 for a 30ml tube of the stuff. It might be good, but it can't be THAT GOOD.....American made, Profit driven product.
I've been looking at this antenna and it's baby brother. I've never built a repeater and I'm still only foundation but I want to build a 10m repeater now lol. I was looking at how to build 10m cans for a duplexer I should be able to make some steel ones. But for now I might just buy the baby sirrio for 10m, yes I know I can make a flower pot antenna I actually have one, but I want a ground plane antenna. I wonder if I would be able to put a 10m repeater on Telecom tower. Thanks. Shane VK1NME.
Building a 10M repeater is a bit of an issue - there are no free frequency pairs without overlapping at the moment. VK2 has WAYYYYY too many allocated. When the band opens up it can be mayhem
The Sirio 827 does incorporate some of the latest antenna theory, compared to some older CB antennas designs. The full length 5/8 wave gives about the lowest angle possible and doesn't need a top hat, nor is one desired. On shorter antennas, a top hat can raise the current high on the antenna, to make it act a bit like a longer antenna, but any longer than the 827 and the pattern starts to split off at high angles. The multi-turn matching coil acts somewhat like an RF choke, compared to the old single loop matching coil. The 8 eighth wave ground radials are supposed to be more effective than 4 quarter wave radials and the radials also help to isolate the feed line from RF radiation. I doubt the ferrite bead RF choke is needed on the feed line. Unlike the other Sirio antennas, the 827 has fairly heavy construction, compared to the lighter ones. The matching coil and radials really help to expand the SWR frequency range of the antenna. The Sirio 2016 is lighter weight, slightly shorter, with a top hat and has a lower wind load, but is not as strongly constructed.
Wow! Already! Thanks Peter. The repeater's receiver isn't fully active, it's still on test - but it is linked to a local repeater here in Hobart for testing, so you should hear chatter on it.
in my opinon 5/8 antennas are not great... they require them to be shunted to ground (the tuning coil) and seem to have poor (poors a bad word maybe less than ideal?) receive... i put a m400 up and never looked back..
@@HamRadioDX im not saying theyre bad. this is one of the better designs ive seen. and all really depends on usage. for dx youre not gonna notice a difference. local usually a different story.

Mostly do Ham radio now. Have a bunch of cb radios I don't use much anymore. Was big into cb late 60's and 70's.@@HamRadioDX
827 is good but the penetrator 500 is the dx king

The import charges and shipping is the killer to get it here. Hopefully the glue lined heatshrink stops those screws from moving
