External Antenna Sockets - Tecsun S-2000 Owner's Manual

EXTERNAL ANTENNA SOCKETS

The external antenna sockets are used to connect the TECSUN S-2000 to advanced performance
antennas.
FOR MW/LW
On the rotated AM antenna, at the top of radio, is a socket for 50 or 75 Ohm plug-in AM antenna.
A loop antenna or an antenna tuner can be connected to the radio to improve the reception of
MW/LW.
External ring type AM antenna
NOTE: it will cut off the internal AM antenna when an external AM antenna is connected.
FOR FM/SW
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.
There is also a black and red socket, labeled 500 Ohms, designed to work with a high impedance
Shortwave Antenna, 500 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 feet 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.
When using external sockets, select EXT. ANT. with the selector switch on the right side of the radio.
When using the internal antennas of the radio, switch it to INT. ANT.
