When measured with a spectrum analyzer, the SWR was found to be 1.5:1 at 978Mhz and 1.2:1 at 1090MHz which is quite good considering the manufacture and frequency. I'd consider transmitting on this antenna with figures that decent (though at very low power).
The antenna is supplied with a decent N to SMA cable which claims to be RG-58/U which should translate to a signal loss of ~2dB in the 10' of cable versus ~4dB for RG178B/U which is common with whip antenna types; you get 66% more signal for the same length of coax!
With a little bit of coax sealing tape, this antenna will be going into service to replace my temporary (portable) magnetic whip antenna.
After installing this antenna at the exact same location as the (compromise magnetic) temporary antenna I saw an immediate increase in maximum reception range on the order of 50km. I also noticed a significant increase in the number of aircraft being received in intermediate ranges (100-150km).
