New antenna from Sirio Gain-Master

Engineers at Sirio? Probably some guy in his garage hiding from the wife turning parts on a lathe.

pmsl, it must be one hell of a garage and one hell of a fast turning lathe to bump out the production numbers sirio do, especially with the quality they give at affordable prices unlike some of the backyard lathe turners in the states that fire out modified stardusters with added coil/cap hat and charge mugs who buy them exhuberant prices and god knows what other bullshit thats been posted on cb forums that these so called antenna builders make and the outrageous claims that go with them,like audio gain,pmsl..


The English on that site is pretty poor. Maybe I'll offer my services as translator.

never ever thought i'd see the day an American offered to translate English for anyone, that would involve a 3 way translation from Italian, to American English (or as we call it here in the UK,piss poor spelt English) then to real English.
 
On the contrary Scott, the only one who needs to admit anything is yourself. You could start by admitting you've been acting obnoxious, stubborn, and disrespectful to me and others in the forum who can spot your BS. Who cares if Sirio calls the antenna a COAXIAL J-Pole, it's still not any J-Pole that you're at all familiar with and has almost twice the gain of a 1/2 wave.

As long as you continue to bagger me with your false signature line, I just may feel obligated to continue to point out how much you post about things you know so little about or how frequently you choose to ignore the facts in favor of controversy. It's one thing to not understand something, it's an entirely different situation to ignore those trying to educate you while you insist on calling them the liar.

Even if I posted the CST GIF file here, you would just say I photoshoped the 12 or 15 individual images contained in the file like you claimed when you were wrong about how it would look approaching a minimum current point in phase angle. I know how people like you work. You're never wrong even when you're completely wrong. You get nothing from me by acting like an ass.

You've been so sure in being wrong about the Sigma design for many years your ego can't allow you to admit it now and you'll stop at nothing to confuse others into to believing it could be your half wave J-Pole with its stock 2 db over a dipole. If you don't like me following you around pointing out all the flaws in your posts, you have some options. Stop incorrectly calling me a liar, learn the material on your own, or shut up and put up with my responses to your attempts to defame me.

Blah Blah Blah, I see several paragraphs but no CST - again, and again - and now I no longer even need to read it, same-o same-o I'm sure.

Still avoiding posting the Vector CST or admittance of having stated untruth?

I really don't even bother to read your posts anymore. Not until I see the CST you claimed to have, your big claims of proof which you insist you won't post for whatever new angle or silly feeble thing you can blame me for again?
Redirect, belittle, ad hominem attacks, endless misdirection, but never your alleged Vector CST.

Man-up Donald, and
...
 
Apparently your signature line is no longer doing your dirty work Scott. Keep misunderstanding things and claiming those who tried to teach you are untruthful and you'll probably remove whatever little asset your posts may contain in the eyes of others. Just let it go already.

That one I did read.

But YOU are the one who made big claims of having proof of your alleged Vector collinear effect in the form of a CST which YOU have avoided posting at every turn while using every form of redirection, ad hominem attacks toward me, misdirection or any other option left to you in avoidance of posting your ALLEGED proof.

I have simple continued to ask you for it.

If continuing to ask that you provide that proof, which you have publicly claimed to have but will not show, is doing "Dirty work" then obviously one of us is mistaken about the character of this forum, it's users and administration.

The question of why my signature has been removed is illuminating to say the least.

Perhaps I am the only one with enough balls to call you out on your inability to publish your so-called proof which you continue to avoid doing.

You may have others fooled and intimidated, but not me.

You keep that mysterious, nebulous, alleged CST nice and safely hidden within your big claims of having it, and as long as you do, know that you have been called out but
YOU DID NOT MAN-UP.

It was removed because it was annoying as hell and making a mess of the site. That and I've received enough complaints that it was time for it to go.

You are the only person with enough balls to bite the hand the feeds you while you disrupt the entire forum. What was that reason you wanted to see my complete CST file again? Wasn't it to show your theoretical "bloom" in the lower 1/4 wave happening at some other phase angle then the top 1/2 wave?

Can you remotely explain how any section of any antenna could possibly reach it's maximum "bloom" point (as you call it) at any driven phase angle other then 90 and 270 degrees? Once you realize how ridiculously impossible your theory is, you might realize why I refuse to share anymore information with someone as ungrateful as yourself.

All the proof you needed was in the first CST model I posted, showing constructive radiation along its entire length. Snap out of your ignorance or keep getting called out on it.
 
So after 75 pages of posts I don't know how much more can be added to all this but here goes.

I will be doing a comparison test of the A99, Imax 2000 and Sirio Gain Master.

I plan to spend a Saturday in a open field and set up using a temporary 20' mast. I'm going to use the same radio, coax and mast and tune and mount each antenna one at a time.

I'll have my MFJ analyzer handy.

I'm just going to go with a Uniden Grant for the radio, 50' of simple mini 8 coax for the test since it's the most common used by CBer's. This should put my vehicle roughly 30' away from the antennas and it will remain in the same position throughout the testing so hopefully it will not be considered a variable.

I'm going to record the meter at my home station on video and have two other stations take readings as I do the testing.

Not the most exciting way to spend a Saturday but maybe it will shed some light on the subject.

I think I'll also take the chance to put a 10K and 102" SS up against each other as well for some perspective.


Since I'm taking the time to do this if anyone has any suggestions prior to my setup that they believe will help eliminate any heresay afterwards please let me know :)

Sounds Great, looking forward to your results.

Thanks a bunch for your efforts… they are greatly appreciated by many, I’m sure. Any attempt at unmasking the real world facts of equipment available to our hobby is welcomed and refreshing as far as I am concerned. The test you propose sounds good to me. At the end of the day, a fellow just wants to know which antenna seems to work better without all the hype and glitter surrounding most products. I have the upmost respect for “all” those who are willing to use their time and abilities in shedding light on subjects that the normal radio enthusiasts would not be able to ascertain alone, short of a direct purchase of said item(s). I have owned an A99 in the past and now presently own both the IMAX 2000 and a Sirio Gainmaster. I am presently using the GM and have been well pleased with it… short of its limited power rating. It is on a temporary chimney mount at about 25’ at the base. I am in the process of selling both antennas because I have a Mr. Coily Enforcer .64 on order. It will be mounted on a used 64’ tower I’m working on now. Thanks again for your efforts and also to everyone else who participates and contributes to this fine forum. (y)
 
i always enjoy your reviews of equipment cbmagman and im very much looking forward to this one :)
any chance you could get a vector style antenna to add to your comparison ?
 
No vector this time around, I just paid out to get a new Cobra 29 LX here and a longer shaft 10K to review so running short on funds.

I was tempted to throw a GP antenna into the mix but decided to keep it simple for the first test.
 
I dont think i know a single person who owns a sirio.I heard they are very poorly constructed and fall apart when the winds get to high.

That may be the case with some of the longer aluminum antennas. I've always thought it was unacceptable to use two screws to hold each section of aluminum tubing together. I found spending a few minutes with the hack saw or Dremel to slice the top of each section for use with a hose clamp and one screw makes a big difference. Some of the thinner tubing towards the top could be heavier too. To be fair, I have to say the Gain Master does not suffer any of these mechanical weakness problems. It has taken winds that have destroyed two other antennas that were on the same mast before. It also holds its own as a top performing vertical omni.

While the Vector is equal to the gain of the Gain Master, no other omni on the market is going to provide more gain then either of these two antennas where you want it. Including all 5/8 wave groundplanes. This is not based on opinion or some S-meter radio check taken at different times. It's done with a calibrated field strength receiver that gives a digital signal reading down to the microvolt level and compared with accurate attenuators against a reference 1/2 wave vertical dipole. Antennas under test are swapped out within 1 minuet of the previous test on one mast that is 1 wavelength above ground. This gives the ability to measure differences within a fraction of a db and removes any variables I'm aware of.
 
I agree but why arent their more sirios around.I know 5 guys with the 10k why would they spend so much more when they could buy the sirio for less.Their has to be a reason.
