FOIF RTK Base Unit (Parts). Working GPS antenna. Working Modem. Working Battery charger. I have not had a controller connected to it. No Controller / No Tribrach / No UHF antenna / No Tripod / No battery supply. I have connected the modem to my own 12v 17a battery supply and had the modem working. I was expecting to purchase the Rover version with the built in UHF antenna. However I discovered this was the base unit. With a controller and a power supply it could be setup as a base station.
