Has Work Well for Me  Time owned: more than 12 months
Upgraded my GP-6 to a GP-9 about a year ago. I liked the GP-6 a lot - I was just needing a little more gain as I use simplex a lot. Noticed the improvement right off. Scratchy distant stations started consistently coming in much more readable. Several friends noticed and commented on my signal improvement. The GP-9 has been flawless so far. Have had one very strong wind storm and the antenna was hardly moving. Have even used it on my handheld... I can hit most repeaters in my area full quieting on 1W. Would recommend.
Only downside, would rather have a neutral color than white.

Good antenna  Time owned: more than 12 months
Excellent antenna.
Installed for about 6 years and always fully functional. The linear coils make it more efficient. Abs junctions are preferable to metal joints. Metal junctions can negatively interfere but minimal on antenna performance. Comet uses abs couplings. Diamond uses metal joints.

Excellent antenna   Time owned: more than 12 months
I bought mine used about 9 years ago. Mounted it up about 15' and have zero complaints. This antenna and my tw-4000a with 25w reaches for miles both repeaters and simplex. Absolutely a fantastic antenna. Recently I moved cross country and donated this antenna to my club for a repeater. Now it's 90' high on a tower at 1300' level and the club loves the way it works. At my new home I bought a new GP5 because of this antenna.

Good omni antenna  Time owned: more than 12 months
A different viewpoint. An XYL I know was on a 2m net I was running and all she had was a little 5w Icom 91A hand held. Her signal was pretty low, hard to hear and in the noise. She ordered up a Comet GP9 antenna and her and her husband installed it at their house. Next net I had to ask her if she was talking from a mobile, there was that much difference. Since then they have installed a 50 watt mobile and are running it on the same antenna. Her signal blasts in to my place. I have had similar experience with others using the same antenna. The propagation is fairly flat from the QTH and that could be a problem if the site is high and the person being called is close and low, signal could possibly go right over top though I have not yet seen that happen. Great antenna when it's set up and working right.

great antenna  Time owned: more than 12 months
My GP-9 so far has worked perfectly.|
Its been sitting at 18 ft for 2 years and I can work any thing within 70 miles.
even worked ISS and LEO birds with it when they are low on the horizon.
can't wait to get it up on the tower.
Easy to assemble and has handled Tennessee storms without issues.

So good, I bought another one  Time owned: more than 12 months
My first GP9 was up for at least 15 years and the antenna failed after taking a lightning strike. I got my money's worth out of the antenna, which survived numerous storms including several harsh winter nor'easters. I looked around for another dual band antenna and think the GP9 is still the best high gain VHF/UHF vertical antenna available today. 73.

SUPERLATIVE  Time owned: 3 to 6 months
I recently purchased this antenna from Radioworld in Toronto Canada. It took me less than 15 minutes to assemble this antenna,I gave it a couple of coats of wax to protect the fibreglass structure.I do the same with the marine antennas on my sailboat.
The antenna performs as advertised.I live about 350 FT above sea level. I would Purchase again. My advice is to take with a grain of salt some of the negative feedback regarding this antenna

Outstanding operation and long lived  Time owned: more than 12 months
I bought the GP-9 from Mick's Dad, Bruce (SK) in 1993 or 4. We've used it through the Santa Ana winds, here in Southern California. I worked fantastic during the 1994 Northridge Earthquake. We had to operate across the San Fernando Valley, from my QTH in West Hills to the North Hollywood border with Burbank.
At that time, we had a Yaesu FT-470 HT attached to a pigtail on 9914 to the antenna 25' above the ground, working another FT-470 on a rubber duck in North Hollywood. The antenna worked like gangbusters!
It still does after over 20 years of use.
