SG-211 User’s Manual

When operated away from the design frequency, these

antennas need a tuner such as the SG-211 to match the

coaxial line from the transceiver. The SG-211 can be used

with either coaxial cable on output to the balun or direct

connected to the ladder line section with the balun

removed.

3.4.4 Long Wires & Inverted Ls

Long wire and inverted L antennas are unbalanced

antennas. They are fed from the right RF Out connection

directly with a single wire. The RF Ground system is

connected to the Chassis Ground and that is jumpered to

the left RF Out connector.

CAUTION: Unbalanced antennas are radiating from the

line as soon as they leave the SG-211. Minimize the

amount of wire inside the radio room to prevent

interference with electronic equipment. Minimizing
