Great antenna Time Owned: 0 to 3 months.
I bought my GP-15 a couple months ago. It sits on top of a 5' antenna mast on the roof of my house. During the recent VHF contest, I was hearing stations 60+ miles away on 2m! The bandwidth is perfect on all three bands. I can work both FM and SSB on all three bands with less than a 2:1 SWR. This is a great antenna!

Good antenna Time Owned: more than 12 months.
I've had my GP-15 for 6 years now. Talked a lot of DX on 6M SSB, and even on 6M FM simplex.

Works great on 2M also. I hit repeaters 60 to 70 miles away on a daily basis.

70cm is the only band I have any problem with. It works OK, but the SWR is high near the repeater and simplex frequencies, but low at the lower end of the band. And there is no way to adjust the SWR for 70cm other than cutting the length of the radiator. And I don't want to do that.

Otherwise, it a great antenna for 6 and 2 meters, with a good SWR and gain factor on both bands. I like that it's a 5/8 wave on all 3 bands.

Excellent Choice. Escepially For The Simi-CC&R Individual Time Owned: 0 to 3 months.
At under 8' you can hide this antenna in virety of locations which is of interest to the antenna farm challenged Op. I had mine on the deck as a temporary measure and from the street it looked like a small flagpole.

VSWR on all bands is as advertised. In my case I could get 6M resonance on both the FM protion as well as the SSB portion of the band by adjusting the horizontal (6meter) radial. While not having it long enough to attest to its longevity, I can say however, at this point I am completely satisfied with it's performance.

Money well spent.

Purchased from R&L. Installed with a short run of quality feedline and have had excellent results on all bands the antenna was designed for. Absolutely zero complaints.

Great Package for the TS-2000 Time Owned: 3 to 6 months.
I feel we are lucky enough to have a 6 meter repeater in our territory - SW Missouri. This replaced a dual bander with about the same overall dimensions. Expected a slight reduction in performance on 2 and 440 but it seems as strong or stronger. Enjoy that is it one piece, looks good and with the Comet CFX-514N makes a perfect package to use with the TS-2000 for FM work. Associated Radio out of KC has a nice price on the package too. Whatever radio or radios you work, if you need all three bands with one coax feed, this is your antenna.

Fantastic, I`d buy another Time Owned: more than 12 months.
Hi everyone,

I am very happy with my GP-15. I can only vouch for 2m and 70cm as I am not licenced for 6m yet but the performance of this antenna is excellent. At the moment the antenna height is only 15ft so it is not very high at all. However at this height I am able to access all of the repeaters in my city and some that are in the country many many kilometers from my QTH. I have had success in working some "Troppo" contacts with this antenna too. In the future I will raise the height of the antenna to a more user friendly height and I am sure that I will notice the improved performance. Highly recommended.

good ant Time Owned: more than 12 months.

Great Antenna Time Owned: 3 to 6 months.
I bought my GP-15 used off a swap net to put up at my girlfriend's house when I am out there. This antenna has surprised me as far as it's performance on 2m and 70 cm. I have not put it on 6m yet. It's only up about 15 feet in the air and I can talk simplex to stations over 50 miles away. In fact, it out performs my 4 element dual band beam. I would buy another one at full price if I ever need another.

Very reliable and good antenna Time Owned: more than 12 months.
My GP 15 is now up on the roof for 12 years! and it simply stays working and working. No erosion on the radials and brackets. I can work all repeaters on 2 and 70cm here in the Netherlands without any problem. VSWR is ok on 2 and 6 meters. On 70cm the badnwidth is somewhat limited but ok in the repeater section. If you are looking for a multi band vertical which last forever, don't look further and go for the GP 15 and you will get an antenna which probably last a life time.

Very Impressed Time Owned: more than 12 months.
My GP 15 has been up at 40 feet, fed with 1/2 inch hardline, for 2 1/2 years now and performs flawlessly on all three bands. I bought it to use on my TS 2000, and am very impressed with the performance especially on two meters and 440. On six, it appears to work as expected for a 5/8 wave vertical. The internal tuner on the 2000 tunes it on the ssb portion of six meters and I have done a lot of side by side comparison with my 2 element horizontal beam. Interesting how sometimes signals are better on the vertical, sometimes on the beam depending on how the wave arrives during e-skip openings. I would recommend this antenna to anyone looking for a well-made, well performing tri-band vertical.

Four Years and Still a Winner! Time Owned: more than 12 months.
I have used a GP-15 for four years. Great on 2M & 70CM but, no 6M FM users around so that aspect is still unused. I regularly run 100W on 2M with no ill effects.
