Well I see H &Y Electronics has raised there price on the GM,
At there store front it was 139.00 now its $179.95 plus S&H
and there Ebay store its was 129.00 now its 169.95 plus S&H.
So I guess its back to the I-Max 2000 for me.
I can't see paying that much for what it is.
If it was a aluminum antenna there would at least be a scrap
value, but a glass antenna can only go to the dump.
Hey there Okiebob,
If you plan to run big power or mount it up through the middle of an horizontal beam then you're probably better off with the Imax, however, if it's just going up in the air by itself well above other metal objects and won't be seeing more than about 500w-600w pep you'll be sacrificing about an S-unit of performance (the difference I saw between my Imax & Sirio GM on the same mast / coax) to save ~$75, plus the Imax is prone to suffering from a considerably higher noise level.
As far as fiberglass, it's rather thick-wall and is easily painted to preserve it for decades without it growing 'hair'.
- Just don't use metallic paint!!
Jeff, the info is on Charlie Tango. I think there was talk of 800 to 1KW on FM maybe, which is an abuse. I don't recall the specifics right now. I think Sirio sent a new harness out with an updated capacitor design, I've asked for more pictures of the inside of the shrink wrap. I think maybe they were anticipating some arcing.
I like the people at Sirio, they're smart business folks and treat their customers right, thank you.
I was told someone wrote something not entirely true so wanted to reply. The antenna melted when used with a KL300 so if that is 1kw then let it be so. Sirio now state, the designer via email 125W AM. 400w SSB and around 40OFM is the maximum the antenna will take as then it arcs, this makes the burn and the antenna is dead. I have now tried all 3 series of the inside, the last is by far the best but keep the power low and not what is quoted via some specifications. So the antenna is weak but works well. BUT, someone local here tested a metal 5/8 with 200w and a Gain Master with 200w and was exactly same signal when tested on same pole. When there video comes online will send you links, it is around 1/2 hour long and shows via editing both sides of the conversation.

Marconi, if I were testing one antenna against another I would be concious about having them parallel with one another. There will be attenuation between them without a doubt. The best way in my opinion is to mount each antenna on the same pole with no other antennae in attendance. That will give you a true measurement.
I can appreciate your difficulty is getting radio reports for your antenna tests.
It is a shame you don't have an FM station about 30-40 miles away who you can rely on for such testing then you could cut out the unreliability of the side bands and the uncertainty of what people are TXing on them.
I have tested Antenna before but i've always used the same location, pole, coax and so forth. I use FM to test because it doesn't get effected as much by conditions out of my control like the side bands do.
It's a shame you can't send someone in a mobile station with a set up to give you better reports.

I agree with you, it easier to do test with FM
because the fm it's more stable signal than am and ssb.
I have owned both I-max 2000 and Antron 99 and I can only say that
GM is better.Before I could not hear my friend who lives 60km
from me when we talk on fm.But with the GM it's now possible.
Hes signal report to me is S5 to S6..I-max and antron have more static
background noise the another antenna I have tried..

Incoming Region Produces X3 Solar Flare |
May 15, 2024 @ 14:55 UTC |
Another major solar flare, but this time from an active region just beginning to turn into view off the east limb. It is possible that the group responsible is old AR 3654 from the previous rotation. The latest flare, an X2.99 event just peaked at 14:38 UTC (May 15). Stay tuned |
