2.1.2 Antenna and RF Ground

Connections

A wide variety of antennas can be connected to the SG-

211. A set of wing nuts for connecting balanced or

unbalanced antennas is provided on the back.

Optimum use of the SG-211 Smartuner is to put it directly

at the antenna feed point. This may require enclosing it in

a waterproof enclosure to protect it from the weather.

Either a balanced or an unbalanced antenna can be

connected directly to the wing nuts provided on the back

of the coupler.

If the Smartuner must be away from the antenna feed

point, it is best to connect to the antenna with balanced

feed line. The feed line can be connected to the balanced

terminals on the back of the coupler. When it is not

possible to use balanced feedline, then the antenna may be

connected with coax.
