Circular polarized antenna's also known as "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. These antenna have 3 lobes which are protected by a 2 piece plastic molded cover that clips together.
Frequency Range: 5725~5875ghz
Cable Length: 60mm
Polarization: Right hand
First off it is very inexpensive while giving me better performance than my stock ducks. I did get a dud once as in I opened it and it looked like it was smashed down purposely. Other than that have always been happy except that one time.Better than stock Antenna, as it eliminates blind spots. Range wise, it does not improve on much, also cheaper than branded versions that have same performance. Hard to compare to other models but it does get the job done.
