The SG-230 is merely connected to the transceiver via a piece of coaxial cable with a PL-259 connector on the
end. Just plug it in and screw on the sleeve and you're ready to go!
In most cases, the SG-230 will be connected to a simple wire antenna or to a vertical whip antenna. The single
"hot" wire must be plugged into the antenna jack of the coupler. No coaxial cable should ever be installed to the
antenna output jack of the SG-230. Always mount the antenna as high and far away from potentially interfering
objects (a truck cab, a steel building, under a steel bridge, etc.) as possible. Otherwise, the signal from the antenna
will be absorbed (to an extent) by the surrounding object and by the ground.
