I have Immersion RC 25MW tx and Flysight 7" Blackpearl monitor. I am planning to get better antennas for these.. Please help me to find one. Can you please post the link.
You probably want 5.8 GHzCircularly polarized antennas. Search for this and you will find many. On the copter use and omnidirectional and on the BP use a Omni on one input and a helical directional on the other input. Make sure the BP is in diversity mode.
