Switch and phase unit details

The switch unit is simple It have to choose 2 antennas in-line and connect them to the output labeled ANT1 and ANT3.
Furthermore it will put up voltage on the coax to feed the RX-amp. There are leds added to see witch relais is active.
I have chosen to put the RF chokes in the same enclosure and solder the RG179 direct to the PCB, but a female F-connector can been solderd on the PCB.
