I recently purchased two 23cm WA5VJB PCB yagi antennas without SMA connectors, that was a deliberate decision as I wasn’t sure how I would use or mount the PCB antenna. For a recent SOTA activation I quickly soldered a short length of RG174 to the PCB pads which served its purpose for two activations, Mt Taylor and Booroomba Rocks. My improvised RG174 solution was not meant to be permanent, so it’s time to fix a SMA socket to the board.

Female SMA socket. The width of the socket base fits neatly onto the PCB pad 🙂
One edge of the SMA socket is soldered to the board’s ‘braid’ solder pad. The SMA center pin is sitting 3 mm above the board. I made up a short 8 mm length of 1.5 mm copper wire to extend the SMA center pin to the strip line folded dipole. I will leave the outer pins in place, their presence will help to protect the center pin.

To help protect the strip line I sprayed the board with a light cover of PCB lacquer.
Finished and ready for portable use
Good luck with your 23cm SOTA activations. 😉
