It's has been long time since I have posted on the forum and I don't recall the rules but getting back to the antenna I have had both the Imax and A99 this is the best tuning as far as swr and resonance I've ever had on either of them. if I wanted to I could improve on the results but it would yield very little I'm sure you can tell that I'm impressed.

Solarcon MAX OPTIMZER The Ultimate 10-11 Meter Base Antenna
- Thread starter Unit 194
- Start date
Good idea LC, but if someone has an Imax and is not using the optimizer section and they have the proper meter for testing, then maybe we can get some more ideas to better under understand what is going on inside,
Personally, I think this nothing more than an extension. Solarcon use to suggest that Ham operators cut the top section. but I have never heard a discussion on how that idea worked.
Here’s the extension at a cheaper price with free shipping.

Video on YouTube of the Imax 2000 that has been cut open, and explains what's inside of it. The extension is just a piece of wire inside to make the antenna longer. Nothing special about the extension...just makes the wire longer.

Then the same fellow made another video on how to make one.

I trimmed mine. I cut way less than I estimated based on the info in the manual, and it changed the resonant frequency way more than one would think based on the manual. Just sharing.
I gave away the Useless ground plane kit for my Antron 99 as did several others that I know. We each found them as a waste of money & more Smoke & Mirrors than anything useful. The Antron 99 works better without the ground plane kit as far as each of us are concerned.
My Antron 99 has a 1.2.1 SWR on 6 meters & I have used it for hundreds or QSO's on 10,11,12,15,& 17 meters & other than 6,10,& 11 meters I used a tuner. It does not beat my yagi's but it works pretty darned good at only 30 ft to the base of the antenna.
Amen, I agree six-shooter.
With my new shorter A99 (12") I only have a nice bandwidth if I go up in frequency. Working CB the match is 1.5:1, which is fine for working my radio, but it's 100+ ohms of reactance.
Thanks
Hey Six-shooter my Exnec models for the A99 with the GPK attached...shows there is very little to no currents on the radials.
IMHO, this how Solarcon gets away with their baseless clams about the GPK, because the radials have little to no current flowing on the radials and that is because with a 1/2 antenna on the 2 radiator ends...there is voltage only, little to no currents.
Maybe I'll post the models, 1 with slanted and 1 with horizontal radials.

The context of my post had nothing to do with how useful or not the ground plane kit was, it was commenting on weather or not the antenna met the advertised claim of being a "balanced antenna". Therefore, at best your reply is out of context.
Speaking to it anyway... As you have a rather strong opinion about said ground plane kit, you are going to believe what you want to believe no matter what anyone says, and that is fine. But there are people (including myself) who have seen adding a ground plane kit to some a99 or Imax antenna installations appear to help said antennas. When this happens there was a problem with said antenna the owner likely didn't even know they had. I tend to prefer other solutions to said problems, but the ground plane kit is an available, workable option when said problems do come up, especially for those that don't have easy access to someone who may have other solutions.
As you and your acquaintances didn't have any of these problems, well that is normal, and I guess to a certain extent lucky. Most of the time people don't have said problems, but sometimes some people do. If you or your acquaintances did have such a problem, would you know how to fix it without said ground plane kit? Would you even know if you had said problem?

Marconi, I would very much like to see the two models if you post them. I'm very curious about this part of the hobby and have enjoyed the various models you've posted in the past. Thank you, Sir!
I still use the Antron 99 most every day on many bands & it performs very well for a FREE antenna. I have had Zero issues with it & it for sure works far better without the ground plane kit so as I said,I Gave it Away. Unless I wanted a worse signal I would never use one again. The Antron does not come close to my (5) band Mosley yagi but it does what it's designed to do & it has now for over 10 years.
