SL3-17-DWC

Fixed-station, half-loop, NVIS (Near Vertical Incidence Skywave) antenna, 150W PEP. Mounted on 6.58’ x 1.2’

(2m x 0.37m) base plate. Requires radial wires or good ground plane and RAT7000B-SL3-17-DWC antenna tuner.

5. Automatic Antenna Tuners

Tuners are needed whenever a narrowband antenna is used in order to transform the variable complex antenna

impedance of the antenna to 50 ohms at the transmitter output.
