This is an easy project that's fun to play with. With 5mW Gunn sources and some dish antennas it should be possible to send video several miles.
The transmitter. The video and power inputs are to the left and the horn is to the right.
The receive pre-amp. This circuit is mounted on the side of a Gunn source. Descending from the top one can see the detector diode connection, a 0.1uF capacitor, the MAR-6 MMIC, the bias resistor, another 0.1uF cap, and the output coax.
