Review on ADSBexchange.com 5.5dBi N-Type Female Antenna (1090/978 MHz) - 24-inch: Boost Your ADS-B Reception! by Maalik Harris

It's hard to compare the performance of this antenna to any other similar antenna because I've gone from an indoor hand held antenna with no resonance to this rooftop thing. Needless to say, it kicks the butt of the indoor antenna pretty thoroughly. Switching to this one went from about 40 messages per second to about 250 using a 50 foot 9913 coax. I have yet to cut the coax and add a filter, but even without these settings I'm more than happy with the performance here. The antenna design seems very nice, on par or better than other Comet and Diamond I have. . I wish the antenna mount was a bit more flexible, but I'm not complaining about the cost. It's certainly solid, and the hardware that comes with it (u-bolts, nuts, washers, lock washers) is of high quality too. I don't know how well it will hold up but so far I'm very satisfied!
