Are you looking to buy Matek 1.2/1.3Ghz VTX-1G3-SE Video Transmitters in Australia?
The VTX-1G3-SE is a revision to the previous Matek 1.3ghz Video Transmitter for Fatshark or other compatible goggles/ground station docks. It is a 9CH 1.2GHz - 1.3GHz Long Range Video Transmitter from Matek. It's designed to match their 1G3 Video Transmitter.
NOTE: If you are using FrSky R9 / TBS Crossfire these radio control systems can interference with the Matek 1G3 video link as they operate on adjoining frequencies. To help reduce interference we recommend fitting a notch filter or using a 5.8Ghz relay station so that the 1G3 VRX can be positioned away from your radio control.
