I'm trying to attached external antennas to BH3BBU mini duplex MMDVM hat I've bought from eBay. I've bought IPX to SMA pigtail from AMAZON and will mount the SMA connector on the box. My question is. Do I have to do anything other than connect the IPXs to the P1 and P2? What is the jumpers TC very close to the IPX connectors? Do I have to disconnect this or can I leave it connected? The board came with both TC jumpers connected (shorted). I believe, but have no prove, that these TC jumpers are the selector between the ceramic antennas and the IPX connectors.
