Circular polarized antenna's aka "clover leaf antennas" are a great way to increase the performance of your FPV system. The circular polarization helps reject “multipath interference”, a problem that plagues standard dipole stock antennas. Proven to increase range and video clarity circular polarized antennas have become the standard aftermarket 'essential' upgrade for modern FPV systems. This is the 3-Lobe transmitter side antenna with a 60mm shaft/cable for a nice clean, direct install with a RP-SMA connector.
Frequency Range: 5725~5875ghz
Cable Length: 60mm
Model: 3 lobe Transmitter
Kinda good quality but for the many you can't go wrong so far they work grate got reception through 3 walls & a few cars doing a test run with scx10 out side well I was warm in side solid signal & just a good deal for the price a must have for the budget minded begener or park flyer / driver ??good for the price if you want super long range gt the immersionrc they work better although cost 3 times as much you might get 3 times the range but for the price these cant be beat.I've purchased several of these antennas, they used to come packaged in a little cardboard box and arrived in perfect condition but the last 2 have arrived completely flattened and bent. It is obvious they were sent like that because the box was well packed with no travel damage. thanks for the Chinese crap hobbyking!!!
