If he knew what the elevation angle of the primary lobe was on the GM, he be shocked to see it beats the crap out of his .64 wave. "Builders" that mistake chokes for loading or matching coils are machinists who use their metal skills to make antennas they don't understand. There is no shortage of that online.
I MAY LOVE A .64 BUT I HATE BAD TESTS!!
Dan, we've never spoken but if you've read any of my posts you'll know I'm a .64λ fan from waaaay back. I bought my 1st Penetrator 500 .64λ in 1975 and still have it.
Yes it's been cleaned several times over the years and now I use Nolox so I don't have to worry about aluminum oxide build up, so my test simply shows exactly what Sirio claim, and there's no way that Swedish test could ever be valid.
If I were him I'd try it all by itself up there, and hopefully at least 18' above anything metallic such as non-insulated guy wire, roofing, etc...
Even if in his limited space he needs to have several antennas in close proximity, (and at that point the SGM is NOT the right antenna for him) at least ask him to try a fair test and try each alone up top, and on the same mast / coax.
- Only then will he know how well the SGM can perform, otherwise it's misleading as hell and makes you look desperate for sales.
The Sirio Gain Master is a balanced antenna and responds negatively to anything within a ½λ or so under or around it, so if someone must have several antennas in close proximity the Sirio Gain Master is NOT the antenna for them.
In fact here at my home it showed about 2 s-units loss on my Icom analog meter compared to the Penetrator which was ½λ away from the SGM until I simply lowered the Penetrator down and out of the near field of the Gain Master, then the SGM showed a full 1S-unit over the Imax 2000 & about ½ S-unit over the Penetrator, (although that test wasn't using the SGM on the same mast as the Penetrator, it was on the Imax mast and soundly beat it, as well as the Penetrator).
Once the SGM was on the Penetrator mast I saw about the same improvement on TX, ~½ S-unit, but receive provided close to a full S-unit gain over the Penetrator!
I've never found an antenna that will outperform the Penetrator500 .64 until now, and that includes the ice cream cone(coaxial)J-pole; Larry's LW-150.
- Oh, and I'll wager the Penetrator & Enforcer are more neck-n-neck than different, with the possibility the Penetrator will slightly outperform the Enforcer due to it's elevated radials slicing off some of the unwanted inverse current from the bottom 1/8λ.
Please have him retest, not just for his credibility but also for yours, and even if your Enforcer loses by a little, (as it should if the SGM is 'alone in the sky') please remember, it's only a 500w-1Kw pep antenna, yours still handles many, many times the power and should only be down in comparison to the SGM with <1kw about a dB or two.

Good job, nice to have a real test. : bravo: "

yeah ok..desperate i wish,i dont post for desperation what are you serious..listen i am only posting a gainmster test..see it as you wish..my computer programs tell me all i need to know as so do all the test and costomer comments..as i figured this would be interesting and as you all can see already you guys jump at the chance..bye bye have a good one.
Thanks BOB Good to know its still doing it.......Homer hello..still reading but very little time to play online...you all have fun very busy so see youball next time..

That was no more a test of the true performance of the Sirio Gain Master than would be testing a dragster by driving it in the rain through town to buy groceries.
I can hear it now, "No place to put the bags of groceries and terrible traction & handling, a total failure".
And I didn't know you had a superior testing facility compared to Sirio.

knock knock the world is a test ground.but you notice whos antenna mine replaced.hmmmm if what your saying is true ill leave it be..73sss
I love it when you and kale come out here preaching that you read the Arrl Book, you first have to understand what it is saying reading it does no good.
Then you make a post that contradicts what you read in the book. You just said longer wave beats shorter, yet somehow your magic cap hats are doing something for audio? LOL it is called a corona ball they have nothing to do with your audio, unles you put something up there with a little size it isnt even adding any capacitance. Yet you supposedly in a keydown took a shorter antenna and beat longer ones? What happened to Longer beats shorter? Oh thats right the audio balls put you on top. LOL. You would get destroyed on the East Coast in a keydown, the West Coast is far behind in that area.
Since it is all common knowledge can you point us to a page , paragraph or sentence that say capacitance hats add audio? We will be waiting
You know what Ill probably be banned for this but you and kale are the biggest jackasses to hit the CB market. You are a glorified machinist with little to no antenna knoweldege, go read all the books you want they arent sinking in, quit looking at the pretty pictures. Your idiotic double coil antenna, triple coil antennas are a joke... What page are they on in the book? Can we see a computer model of one of them? you know the one you keep bragging about using or the book you keep reading. Wow your enforcer looks just like a Sirio antenna what page was that on in the book.
You can go on other forums and get away with that crap but not here Dan/ Mr Coily but the people on here have you pegged and have more knowledge than you and kale put together. Go back to your lathe your gonna get destroyed out here when it comes to technical talk as noticed you run and hide when it gets technical, always oh Im too busy yet somehow you make another 3 or 4 posts Yeah real busy . :headbang:headbang:headbang

I think the "elevated radials" on antennas like the Penetrator are being misunderstood as technical advantages rather then the mechanical ones the antennas mounting bracket was designed to address. This has to do with removing mechanical stress on the insulator and does not make any noticeable changes in gain or TOA.
That bracket that holds the radials is made this way to give support to the insulator. It is also grounded and closely spaced in parallel with the first foot or so of the radiator. Sounds like no antenna action is taking place here. That combined with the fact this insulator adds no significant capacitance like overlapping tubes with an insulator between, is why this antenna tunes longer.
This type of mounting bracket was very common on antennas ranging from the high end Penetrator all the way down to the $9.99 1/2 wave Polecat from Copper Electronics back in the day. The manufacturers knew why they did this and never implied the bracket improved performance. Also remember they only market .64 wavelength antennas to CBers for a reason.

@ ButtFuzz:Please advise me to what is a good replacement mic for my SR-497HPC... Answer: 497 is "wired like Cobra", so many choices available. That radio does not need a power mic, so purchase a stock "coffin style" mic with a decent cord, like the ones that Astatic uses. The Superstar DM-507 is my go-to. https://www.ebay.com/itm/3050474478...adANq91JSiEEnz8EGqPJRBloTgEyaVsBoCtoMQAvD_BwE $12.99 + .99 cent shipping.
