High-quality Japanese antenna. It has a good feel to it, seems sturdy and well-engineered. I can pick up repeaters about 50 miles away on 70cm and I am surrounded by buildings. My antenna is mounted about at my 2 story roof line. I am using less than ideal coax so I bet the range could improve with a different line run. Everyone I have talked to through the local repeaters says I have excellent signal and audio.

5.0 out of 5 stars Amazing quality for the money!
Reviewed in the United States on January 27, 2020
This is my second Comet antenna and I am always impressed with the quality of the packaging and product of this brand. This antenna is very easy to assemble and install. Once up on my roof the performance was awesome compared to my old attic setup. I was able to hit the Mt Greylock MA repeater from New Britain CT (75 miles) with some background noise but fully intelligible.

I did not use the short bottom tube that comes with the antenna because I wanted to connect the bottom tube directly to the chimney mount instead of having two sets of mounts as the instructions show (cleaner looking - see pic). I took a 4 foot length of galvanized pipe that was the same diameter as the supplied tube and used that. I did have to seal that at the junction of the tube and antenna and drill the screw hole in the top but that was pretty easy.

Overall I would highly recommend this antenna to anyone looking for a stealthy and well made dual band base antenna.

5.0 out of 5 stars Great Antenna for its Size
Reviewed in the United States on June 26, 2021
I needed a dual band FM antenna that would go in the attic (HOA restrictions). I've been very pleased with the results, especially on the 2M band. My "installation" isn't totally complete as right now it's mounted on a Christmas tree stand sitting on the rafters just above the fluff. I will soon being moving it about 7-8 feet higher above the air handling units and most of the ducting. I think this is affecting the 70cm band's results. On my in-line SWR meter I never see much above 1:1.5 on 70cm, though the nano VNA results (attached) show much worse.

My only regret is that I wish I'd bought the GP-2; there's plenty of room up there and the extra gain would have been nice. I probably will and keep this nice little antenna for camping.

UPDATE:

Got the GP-1 antenna on a platform above the air handling units now and above most of the ducting now (6-7" higher). Reran the analysis: The 2M band is a lot smoother now. The 70cm band isn't all that much different. I have a MFJ dual band tuner on backorder and I'm sure it will have no issue getting them both tuned 1:1 at any of the frequencies on either band. Raising it did improve some of the more distant repeaters I can hit though, some 40-50 miles away (haven't tried further yet) on the 2M band. 30 miles seems to be a limit on 70cm, but that's pretty good for that band, though there is one at 39 miles I can key. (no signal reports on it yet)
