EXTERNAL ANTENNA SOCKETS

On the right side of the radio are the 50 Ohm BNC sockets for FM
and Shortwave. 50 or 75 Ohm coaxial cable can be used to feed the
properly designed antenna. To find antennas we recommend that
you perform a web search by typing 'FM antennas' or 'shortwave
antennas' into an Internet search engine.
There is also a black and red socket, labeled 500 Ohms, designed to
work with a high impedance Shortwave antenna, 300-600 Ohms,
such as a long wire antenna. Plug a long piece of wire, 10 to 35
meters or 30 to 100 feet, into the red socket and position it above
ground, running in as much a straight line as possible, not touching
any other metal objects. If you do this indoors, position the wire
as close to windows as possible. Plug a 10 to 20 meter or 30 to 60
foot wire into the black socket and let it run on the floor or ground.
Or attach the black socket to a cold water pipe with as short a piece
of wire as possible.
On the rotateable AM antenna, at the top of the radio, is a socket
for 50 or 75 Ohm plug-in AM antennas.
When using external sockets select EXTERNAL with the selector
switch on the right side of the radio. When using the internal
antennas of the radio, switch it to ANTENNA.
NOTE: always unplug all antennas that are mounted outside when
a lightning storm is predicted.
