Solid performer  Time owned: 0 to 3 months
This this is much stronger than my previous antennas. I did not have any of the issues mentioned in the review below. Will note that these are two 5/8 waves on 2 meters as Comet does not see to publish this spec.

I did paint mine green and scuffed the shine off it with a scotchbrite to blend in with the trees around my house. This should protect the fiberglass from the environment.

Great little Antenna  Time owned: more than 12 months
I've had my GP-6 2 years now and have moved it to a different location once. It's works nicely. Hasn't ever given me any trouble and has stood up to a couple of wind storms I didn't expect it to. I get great signal reports and it competes nicely with it's bigger brother the GP-9 if you're not in the mood to have 16' of antenna in the air.

Would recommend.

My only complaint, I wish the fiberglass was gray or dark blue. White looks nice but doesn't work well to hid the antenna against the sky.

tap the carpet  Time owned: 0 to 3 months
glad I read the eHam reviews for this Comet GP-6
Rest assured, tap the antenna which hides the element far from reach - with some tapping, and twirling the center element did drop down (now get to the screws)
Otherwise easy to put together -

Check Workmanship  Time owned: 0 to 3 months
Just purchased this antenna in the last several days. I agree this is a nice antenna and it is preforming well in it's temporary location. I didn't have any trouble retrieving the upper section from the fiberglass tube but the lower section was far enough into the fiberglass shell that the lower set screw was not accessible. I pull lightly on the couple and it came up easily so I was able to connect the two sections. Finished the assemble and installed it. Frist mistake not check the SWR on the ground. Once up the SWR was horrible 2 to 1 or more on both band. Checked the feed line which was new, no issues. Took the antenna back down SWR still the same but noticed that at times it would dramatically improve then go away. Long story short found that the first solder joint up from the load coil was defect and that all the internals above that where just floating in the fiberglass tube. Clean and repaired the joint. SWR well within specifications. Someone simply didn't completely solder the connection. 73,

very good dual band ant  Time owned: 3 to 6 months
I was very impressed with the quality of the hardware that came with this antenna. Aside from the "where is the other end" problem that others have had with putting it together it was easy to assemble and light to work with. The performance has been good and the swrs respectable.

Very Good  Time owned: more than 12 months
I have found that the GP-6 works very nicely for me. Having assembled a Comet antenna like these before (GP-2?) I knew there was a bit more to it than just screwing everything together. The only 'trick' to it is to read the instructions and don't do anything obviously destructive.
Performance? It's certainly an increase in performance over a couple of previous antennas I've used. A 'hear-able' increase in performance, not just 'numbers'. The matching isn't good over the whole band (either of them) but how can you realistically expect that? The biggest difference between the first one I have and the last one put up was that connector in the middle, changed from metal to plastic. So far, I can tell no mechanical difference. The first GP-6 and the last one I bought are both still in service and doing well.
Would I recommend a GP-6 for average 'home' use? Yes, I would, and do.
How about for a repeater? No, it's just not designed for that, not 'heavy duty' enough.
I'm happy with the GP-6.

Even recieves 800mhz  Time owned: more than 12 months
I've had this antenna right at a year now and its works great! I have it mounted to the eve of my roof which is approximately 15ft high and primarily it with my Icom IC-7000 in the VHF/UHF bands. I recently bought a Uniden HomePatrol police scanner and connected it to it to see how it would receive the local police frequencies in the 800mhz band. Needless to say I was amazed how well it worked! I didn't think a 2m/70cm antenna would pick anything up, boy was I surprised!

poor instructions hurt it!  Time owned: 0 to 3 months
I should have come to Eham before I bought the antenna so that I was aware of the instruction issue. I ended up cutting down the fiberglass sleeve to reach the inner portion of the antenna. Now I have a weak antenna with poor SWR. It looks like I'll be replacing this with another brand antenna.

Not a happy camper  Time owned: 0 to 3 months
I had a Comet GP-15 mounted for 12+ years without any issues. I noticed that the outer coating had taken a beating from the sun/weather. I decided to replace it before I had any issues ( I don't like heights!). Since I don't use this antenna for 6 meters, I decided on the GP-6. Surprisingly, most signal reports, as well as receive seemed a bit lower on the GP-6 than the GP-15.
After it was up for 2 weeks, I noticed erratic SWR. I climbed back on the roof (I hate heights)and took down the GP-6 and emptied about 1/4 cup of water from the antenna.
I made a call to Comet to inquire about this. Apparently it was my fault for using coax seal. There are two weep holes next to the connector that I blocked.
I dried the antenna (as per tech support), put a small, tight wrap of tape around the connector and it back up.
The next rain storm showed high, erratic SWR. Back up on the roof went I (Did I mention I hate heights?) The weep holes weren't blocked, but when I opened the antenna, everything was dripping wet inside!
I took the sections apart and sealed them well. I also added some silicone to the connection and put the antenna back up.
After some rain, the SWR was erratic again. One more trip up to the roof (have I previously mentioned I hate heights?) only to find the same thing. (the inside of the antenna dripping wet!)
I've only had the antenna up for 5 weeks and had it up and down SIX times! (4 up and 3 down).
When weather permits, I will make my final climb (Yes, I don't like heights) to replace this annoying piece of junk with another antenna. The SWR, and we haven't had rain in a week is 1.7:1 on VHF and over 2:1 on UHF.
Hopefully I can get my money back (minus shipping, of course)and mount an antenna that doesn't need weekly service.
