wiring
cut two pieces of thin wire (1mm)
solder one end into the SMA connector on the ground ring
then solder the second one into the central pin
bend both of them into opposite directions
cut precisely the tip so that they will be 86 mm length measured from the outside of the sma connector
antenna cover
insert the tips of the wires into the frame
gently slide them so that the connector fits in place
epoxy glue the cover (don't put too much glue if you want to be able to reuse the connector)
