BKR9000 Antenna Comparison

In this video I test the transmit capability of 4 different antennas that can be used on a BKR9000 VHF radio. By using a fixed, distant receive spectrum analyzer with a max-hold function, I did a practical signal strength comparison. Transmitting from the same spot and holding the HT in a similar manner for 3 different frequencies, for each antenna type. Main findings were that the 1/4 wave rangemax antenna BKR0813 did provide slightly better performance, but not enough in my opinion to use over the BKR0810GPS-E or the old KAA0818 with an sma barrel. All 3 of these antennas help improve gps signal levels above the internal gps antenna. The BKR0892-180 was an overall disappointment for the vhf and gps, with measurable performance differences in both.
