About this project

Scope of the project is to create a 3 antenna video receiver diversity (so triversity ...as new word) based on Arduino RSSI signal management to move a pan/tilt system. The code is based on 3 antenna RSSI signal, one UP and two DOWN. The two Down are Left (SX) and Right (DX), the mean value of DX and SX is taken as DW value. Based on this scheme, a step motor is used to move 360° continuosly the dome. On the dome is fixed the antennas that are tilted by a 90° servo. This to follow a quad (drone) or Airplane in the upper hemisphere above the antenna location.

actually it shall be fixed the triversity code, the pan code for the stepper and the tilt code for the servo, the code for the 128x64 OLED.

to do not complicate the code, the central antenna is taking the video signal to a diversity receiver plus a omnidirectional antenna, then the video to the goggles of FPV user.

But it is also possibile to manage a total of 5 receivers and then create an additional diversity, one with the central directional antenna and one omnidirectional antenna, all this by using two 4066 cip.
