2 layer board of 1.47x3.17 inches (37.24x80.47 mm).
Shared on February 22nd, 2016 13:23.

Boscam RX5808 based 5.8GHz Diversity Receiver

v0.2: Pattern fixed, SMA can be soldered on same side.

Schematics and code by JReise http://jreise.de/2fachVideoDiversity/Daten/Schaltplan.jpg

Upgraded with auto scan an spectrum analyser using an Arduino Pro Mini with RX5808-pro Software https://code.google.com/p/rx5808-pro/wiki/Overview?tm=6
Note that you have to change one pin assignment in the code before compiling: #define rssiPinA from A6 to A5!

It is designed for the cheap ebay clone boards with this kind of pin-out (you can also use its tactile switch for S1)
