3) High-impedance 500 black and red spring terminals for shortwave (SW) antennas. These sockets
can be used with (for example) a long wire antenna. Take around 10-35 meters (30-100 feet) of wire and
plug it into the red “SW ANT.” socket . Position the wire above ground and make sure that it runs in a
straight line as much as possible. The wire should not touch any other metal objects. If you do this indoors,
position the wire as close to windows as possible. Then, plug a 10-20 meter (30-60 feet) wire into the black
“GND” socket and let it run on the floor/ground. Alternatively, connect the black spring terminal
to a cold water pipe with as short a piece of wire as possible.
