Circular polarized antenna's aka "clover leaf antennas" are a great way to increase the performance of your FPV system. Proven to increase range and video clarity, circular polarized antennas have become the standard after-market 'essential' upgrade for modern FPV systems. This is a matched 3 leaf Tx to 4 leaf RX set with no cable length for a nice clean direct install with RP-SMA connectors.
Frequency Range: 1080~1380mhz
Cable Length: 0mm
Good antenna i test my FPV more than 10 km.have been using I B C R A Z Y 's but the antennas were for 900 and I was sending on 1.2 so bought these. my range was cut from a few hundred yards to 30 feet.
yes I used them correctly just swapped them out turned it on and just awe full.
an 11 dollar lesson, you get what you pay for on these.
