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 antenna's have become the standard after market 'essential' upgrade for modern FPV systems.
Frequency Range: 1080~1380mhz
Cable Length: 100mm
Connector is not compatible with LawMate RX-1260 1.2GHz 8Ch Wireless A/V Receiver and LawMate TM120500 1.2GHz 500mW 6Ch Wireless A/V Transmitter Module. You need the oposite conector with center pin.Set did not work well for me. Had good range on my FOX 1.2 with stock dipole antennas. Ordered and tested this set, and got about 50 meters or range on all channels. Cannot recommend them.I got these as the SMA ones were out of stock. I used some adapters and connected them to my 500mW 1.3GHz Lawmate TX and RX. Terrestrial range so far is 6km . With a helical antenna on the RX I'm getting 12km .
They are not the best quality but they work well.Why do they even stock this connector without the centre pin?
No one uses them and they make a mistake and buy them!
