- Both antennas are mounted @ top of the mast at 33' 8". This video will show both the signals from the 27.099 mhz beacon and channel 19 voice.
It is difficult to catch guys on 19 driving around, they tend to make short comments and often doesn't give time for a real clear switch, but a couple of times I did make the switch that seemed to capture a noticable difference. This is a little easier here in front of the radio than it looks on the video however. Notice when I identify the antenna I have already made the switch, I'm just old and a bit slow.
Had an Imac for 4 years and very happy with it.....no issues..
I've used the MACO v 5/8 and I've used the Amtron-99. Neither touched the performance of my Imax 2000. The Imax had better ears on the RX compared to both antennas and the Imax had a wider bandwidth too. The only negative remark I have is sometimes when it starts to rain the Imax will howl or whistle like the rain drops were causing some kind of internal static charge but that only happens sometimes.
Flash, I didn't like my personal Imax, but I heard too many working good out there in radio land. I'd be a fool to say anything bad about the Imax. It is generally a very good antenna, and it often does not get the good vibs it should.
@@eddiemarconi3420 I'm getting ready to change out my IMAX because it's got a lot of time on it and it's starting to give me some issues. I've gotten my money's worth and then some out of that antenna. I'm going to give the Sirio tornado 5/8 wave a try. It's an all aluminum antenna. I don't expect the bandwidth to be as good as the IMAX. Still I hear a lot of good reports on those antennas and a lot of the people around my area seem to have good results with them. When I get it set up I'll make a TH-cam video using an antenna analyzer for everybody to see.
My first ever CB base antenna was the Antron A99 fibre optic antenna but now i have the Sirio Gain Master and i must say i have better reception with the Sirio Gain Master. The Antron A99 is definitely a good CB base antenna as backup but i use the Sirio Gain Master which i highly recommend!!!
A couple of months ago I got from here in Ireland to New York state with the FT-818 and 5 watts into an Imax 2000 running on the Windcamp internal battery on 10 meters. NO radial kit.
Good report.
An Astroplane? Wow . . . I remember those antenna's and even had the original Avanti model back in the mid 1970s and it was one fine antenna. Then I switched to the Sigma 4 and that was an even better antenna but man was that sucker TALL! Today I guess it's known as the Sirio Vector. Either way I'm glad they still make them in one form or another, just hope it's just as good!
You have one hell of a setup there with your radio and antenna's being used. That is indeed one heck of a radio station.
That was a great performer, but your right, to big.. everyone I put up got ripped by the winds and finally a struck by lightning lol
Thanks Mr. Bakerman. I have a S4 and an old and a New Top One which was a knockoff of the AstroPlane. I always got good service from those antennas.
My Imax is working beautiful on 10 meters 59 reports from Brazil, 56 reports from Japan.
Spoke to Ireland from Virginia using a Galaxy 2547 on side band, 12 watts, using an Imax 2000. I felt that was exceptional performance.
I just bought a new I max 2000 and I will install it next weekend. I will also leave my A99 up as well. I max seems like a great antenna. I qso with a ton of people who use them
that's good info unlike some of those assholes out that look down on you for trying to learn from the ones that know,thank you.
I have a 2547 too and it is an excellent radio on Tx and Rx. I have a high regard for the Imax too. Thanks for the reply.
Conditions. You could talk on a light bulb 💡 if conditions were right. Well not really, hope you get my point.
ever heard of mutual inductance? it's what happens in beam antennas. one antenna acts like a reflector, due to variance in resonance. you get less signal from that antenna. you need to distance each antenna from one another. your creating an antenna specialist supper scanner. even if both aren't being fed a signal.
Dale, it was just a hobby.
Something to consider: Could the Gain Master be blocking the signal from the beacon so the other antennas could not see the signals? Test the antenna farther apart and not side by side.
I'd like to see a number of dead key AM signal reports from receiving stations comparisons. 5 miles, 10 miles, 15, 20 etc. Compare dead key with the GM compared to the iMax. I think that is another useful validation of these antenna's performance.
I got me a ⅝w GainsMaster too, but can get better results from a T2LT ½w on 10/11m, both yp vertical at 36ft.
Both work great tbh, i love doing comparisons on Fm locally which is upto 50m away, am pearched high ground so get mi'sel hesrd across the Nw Coast & Lancashire 🇬🇧 407 👋 Great video. 😊
I really couldn't tell the difference between the two to be serious but then again I'm using the signal keep 27 so yeah I don't hear anybody
Had two Gainmasters and Both snapped. I live by the sea and winds get strong here. My Imax is about 8 years old but spent a year in the shed until my 2nd GM snapped. Now the imax back up and surviving all the winds once again and it has a new coat of clear epoxy resin. I dont use Varnish. The Gainmaster never got me any better reports locally.
Thanks GF, I live on the Texas Gulf coast about 50 miles inland, and I know what your mean. I would recommend an Imax any day if your area has good strong winds from time to time.
Had my Gainmaster up for 8 years. I painted it when it was new and it worked perfectly until it got whacked. I’m convinced people don’t place the hose clamps close to the edge and maybe over tighten it.
@@ronedwards8239 i left a good foot inside each section and i used 3 hose clamps on each too. Still snapped. They are too heavy like plummers pipe. Those that copied the GM design and used a telescopic fishing pole instead have no issues. The gainmasters construction is just too heavy. They did it for strength but it also kinda works against it.
@@ronedwards8239 First Gainmaster i had replaced my Shakespear Bigstick. And that could take loads of wind yet it was light. The GM was heavy as hell. Hold it out like a fishing rod and you can feel the kind of strain its going to be under shake it about and it gets heavier.
Net Result OM ;
Gain master or Imax ?
When it came to communication It was clear the IMAX heard better..
Hey David, I have thought about this video and it is possible I did not even have the coax connected to my switch box...that booger was way to quite for an Imax.
Thanks for the reply
SEEMS WORKING GOOD....+73's
Sirio i find better built and better QA control on there antennas.They are two types of gain master now HW model half wave and the longer version gain master 25-30mhz broadband,well in Europe,UK they are not sure if HW version in USA?
Very popular in UK for cb\10m use,but for line of sight use they are best mounted at least 50ft up from ground as have a low angle of radiation pattern.The HW having slightly higher angle of radiation pattern,and better suited when low down at sea level and have high terrain surrounding you,again mount these high up for LOS (line of sight) use to get best performance.
Rob 73's
Hey Rob, I don't radio anymore, but I wish I had tried the HW GM. If it is as good as the CF HW GM. then is is a good antenna...and I prefer a 1/2 wave up high anyway.
Thanks for the reply.
Just want to add in conclusion I have built a full wave loop that out performs the IMAX and I have no doubt it will out do the SGM. Search Dream Catcher full wave loop to hear in in action on You Tube.
That is quite a difference. My question is are all other factors of same same period? I’ll bet not do you have Denton at the same height what about the coax are you running the same coax? I’ll bet not other than that seem like a pretty good comparison I’m not a big fan of the IMAX or a99. I must say the Antron voodoo is not working for you this day.
Imax better signal for half the price and stronger in the weather.That gainmaster will snap if a ant farts anywhere near it.
Yeah... it did snap on our first gale winds when I put my Gainmaster up. But I know why it did. 'cause my friend wich tightened the screwes on the joints overtightened it so I in fact heard it crack in the fiberglass. So that is that... but I still think that Gainmaster should be made out of stronger material or something like that! - Why don't they make an antenna out of carbonfiber?
@@ArntPetterAndersen Cost...
@@DimRoditis Yeah.... you're right... That actually suxx...! They would stand the winds for sure :P
Yep Doug, my GM was up for about 5 years on the same Pushup Pole, but I've heard some guys have them fail. Just another sign of the times with these young folks today...it is a throw away world now.
Are the antenna poles equal in height? Are the coaxes the same length and type? What about the connectors/couplers?
Before you go comparing antenna learn how to use your radio. Your on LSB and should be on USB also your radio has 2 antenna ports. Plug one into each and test it that way instead some jank switch box that could cause you all kinda issues.
Jrocker, there was nothing wrong with my switch box, I did not have the coax to the Imax hooked up at that time...just look at the video again and you will see the Imax showed absolutely no signal at all and had not noise either. I did not discover that until I looked at the video much later. Ole Grampa messed up.
I had an Antron 99, then put up a Sirio Gain Master. No difference on 10 meters groundwave to ANY station I talk to regularly. The Gain Master only work on 10,11, and 12 meters, and is very power limited. The Sirio Gainmaster is coming down this week (I just bought an IMAX 2000).
Same thing here, compared both and keeping the IMAX
Lol imax is crap brings in lots of crap
Hey chris, this is just a hobby, but I'm trying hard to become a professional like you.
Would have been a little better test with the AGC set to fast.
You maybe right Marty. I never setup the AGC from the factory,
Shows the gain master lives up to its name. you have better RF gain.
lol, what were you smoking, the IMAX was consistently stronger?
Haha, that's the finest crap I've ever heard
Wrong you cant call raised noise floor/ static noise stronger!. I have both Antenna's myself. And the imax always sits higher on noise floor. My thunderpole 5 has an even lower noise floor that both of them.
@@davidisraelyan5017 I actually prefer the imax i use one myself but it does have a higher noise floor than the Gain Master. I dont rate the Gainmasters construction its too heavy i've had 2 snap.
I bought a gain master and my a99 was superior on dx but not local took down the gainmaster and sold it
your off freq try am 19 not LSB
100, it was just a steady transmitted noise man, and it was broadcasting almost exactly on the frequency shown on the radio.
Hi, I could not figure out which antenna is better.
you prefer Imax 2000 or Gain Master.
Thank you.
Wladimiro.
I think all of my CB vertical antenna work about the same if I get em' close to the same tip height, but I did really like the GM because it was generally a quieter operating antenna with that almost perfect common mode chocking coil at the bottom.
Thanks for the reply Mr. Parigi.
GOOD JOB!
Thanks Magic Man, you are too kind. I think I messed up in that test...and the coax was not even hooked up to my switch box.
EACH TO THEIR OWN,AT LEAST HE IS HAVING A CONSTRUCTIVE EVALUATION, NOT PLAYING WITH HIMSELF WHILE LOOKING AT HIS BEAM SPIN AROUND CAUSE HIS WIFE WONT PUT OUT!
That made absolutely no sense
Thanks Mitchell, sometimes these guys just can't be happy.
Whos win?
What happened to this dude
could be the coax
dear youtube, please take this video down because the content is bunk. this clown can't work his own radio, and he is working his radio illegally by the way.
Sorry, I took so long in getting back to your response Procto...I've been in jail.
Bad information can be better!!!
Firstly, you are using an antenna switch which you soldered, how do you know that the antenna switching box isn't attenuating the imax signal? To do this test properly you need the imax on the same mounting pole with the same coax as you used with the gainmaster. You cannot conduct a test with two antenna's on different poles with different surroundings, it's just not equal conditions for both antenna's. Your tests are a complete waste of time.
2008, I dedicate this testing just to you, so when you get on the Big Boys band you'll have something constructive to discuss.
I have great reports with my IMAX 2000. Very good ears as well. A better receive antenna is a Double Bazooka even lower in height. Can't wait to make one into a vertical. I have no doubt I will beat out the SGM. 73's Check out my DSB on You Tube.
Dream Antenna Designs no one cares about your double spooky double triple antenna dipole dreamer
DAD, I'll try and look you up...I enjoy other's ideas too. Thanks for the response.
sirrio vector 4000 better than both !!!!!
Ron, my Eznec model agree with your opinion here.
Stop using a CB antenna ! lol Why are you using a TS 570 on 11 meters ?
because he can and he wants too
deal with reality.the hf radios probaly make more sales to 11 meter ops than hams.as long as they dont tx on your spam bands why do you care?IT AMAZES me how hateful spams are esp when they started on 11 as well.why be a slave to another federal slave form by having to pay to use aurwaves they dont own.did the goverment create the airwaves? god did.they would charge you for the air you breath if they could.so they just pollute it instead
also ist of its jealousy.i hear 11 meter ops using 10.000 12.000 doller rigs on 11 and hams that cant afford one has nothing to say other than,your breaking the law.yet hams spend all day on 11 meters wen the dx opens complaining everyone is breaking the law.often they will jam 38lsb eith cw to try and stop anyone from shooting skip.also in 2018 skip was deemed legal on 11.deal with it
Old geco hurt probably wasn't always "Triggered" by such little concerns, but when he grew up...they found no peace in their heart.
@@glennclark7472 you are right in everything you say.. virtually all hams started out on 11m which is why they always turn up dxing on there when the skip is rolling in, also using their big burners to crowd out the cb'ers thinking this makes them special.. i got my ticket to use other frequencies legally and not to join the pompous pricks who sit there bragging about how good their kenwoods and icoms are. No wonder the ham bands are becoming dead and repeaters are closing down.. while 11mtrs is thriving again.. hams kill their own hobby then take it out of cb'rs because somehow they think they are better.. makes you sick, snobby bastards.
nope
I can't believe I've just watched this crap .
big fucking chicken choken radio man
They are corny, no doubt Stu.
First, how are the antennas tuned? What is the SWR on both? Secondly, how about using a radio that was made for CB and not using an amateur radio. If you want to play chicken band, use a chicken band radio. Do NOT tell me it's legal either. I am an Amateur Extra and a CVE for amateur radio testing. Which, with the questions you are asking I doubt you could pass the tech test!
I guess this old video "Triggered" you in the worst way possible, like a lot of folks in the World today...seeing as you are so upset. It figures for an Ham like you. Making this video was a like a work of art, if it bitched you out for one minute, an Extra Class and a CVE all rolled up into 1 to boot.
Glad you having such a bad day.
@@eddiemarconi3420 I agree with you.
glendor2, U are DUPEK!!
Gainmaster dragging in all the qrm 👎
James, I found the very opposite, but I had a ham buddy that had a similar problem with the GM and he found his coax was crushed in shipping or packaging, and on repair the antenna worked better. Sirio sent him a new wire setup and they said such problems have been addressed.
Yep Imax and Antron are complete cheap junk.
Imax is great if u want 9+ s points of crap coming in . Gainmaster is much better is high static situations . All i hear on the radio is people moaning there getting 9 s points of shit on there i max lol
The imax does have a reputation for noise and my GM was always quieter than most of my other CB antennas over time.
