Great little package!  Time owned: 3 to 6 months
I purchased one of these antennas. I mounted it in the back side of the roof (not to intefere with the sunroof) with a permanent hole, teflon, brass nmo mount. There was hardly any difference compared to a quarterwave on the ham 2m band! (Both on tx and rx) I do not know how it compares on 440, there aren't any repeaters in operation right now. The bandwidth is a lot narrower though than a simple quarterwave whip. A quarterwave whip has about 20Mhz bandwidth, this one covers simply the ham 2m band adequately, say about 4-5Mhz with decent SWR. This antenna is a great antenna for those using only the ham band, but don't expect to transmit MURS, GMRS or high band commercial without high SWR. And if you try to cut it down or adjust it, it ruins the 440 tuning. You kind of have to "balance" it out just right for ham use. I would recommend it for ham use only. If you are looking to cover business and ham, purchase a ham 1/4 wave and cut it down to around 18.5 inches. This should cover 144.8 to 159.0 Mhz with about 1.6:1 SWR on each end.

amazing  Time owned: 0 to 3 months
I have been using this antenna for a month now. Of coarse being only 14" tall, it can have a disadvantage with some installations,example: trunk lip mount. But having said that, there is a very, very small difference in both receive and transmit performance, when comparing it to a much taller antenna. When installed on a vehicle roof, I could not detect any difference in performance. The installation instructions say that it should not be used on a magnet mount. It requires a solid ground installation. It has a look that compares to a cell phone antenna.

Stealthy & Effective!  Time owned: more than 12 months
I've had one of these little gems for over a year now, using it first with a FT-90R and currently with an FT-8800R. Handles up to 50 watts without a hitch. Truly amazing gain (2.15 Dbi)for all of its 14 inches. I work in Boston and the cellular-antenna similarity has apparently deterred theft in some less-than-desirable areas - or I've just been plain lucky all this time! At about $40, you really can't get such a remarkable low-profile dual-band antenna.

Small but powerful!  Time owned: 0 to 3 months
A great antenna for those with overhead clearance problems. I've got mine mounted on a trunk deck; no problems in even the shortest of garage door openings.

Peformance on 2 meters and 70 centimeters has thus far been outstanding! Coverage is a good, if not better, than my Diamond NR770NMO which is twice as long.

Good value for the dollar!

Outstanding!  Time owned: 3 to 6 months
I just recently purchased this duel band antenna to use on a roof mounted NMO mount. This little wonder has a 1/4 wave on 2 meters providing 2.15 db gain and when using 440, it has a 1/2 wave providing 2.15 dB gain. This little antenna will take up to 100 watts and the VSWR is less than 1.5:1. In my local area, it looks alot like a cell phone antenna which decives would-be thieves, and does not stand out. I can hit all the local repeaters just fine, and kicking 50 watts through it, I am able to communicate simplex as if I was standing outside the other vehicle I'm talking to. A very reasonable price, and a small footprint with alot of go!

BEATS ALL SHORT DUALS  Time owned: more than 12 months
FANTASTIC LITTLE ANTENNA!!
JUST OVER A FOOT IN LENGTH!
$39.95 MOST STORES
SLIGHTLY LESS PERFORMANCE THAN A QUARTER WAVE ON 2 METERS.
EXCELLENT PERFORMANCE ON 440MHZ
UNLIKE MOST SMALL DUAL BANDERS, THIS ONE ISN'T JUST A 2 METER QUARTER WAVE MARKETED AS A DUAL BANDER!!
