LEDR “F” Series The rear panel of the LEDR “F” Series radios is shown in Figure 12.
Refer to the descriptions that follow for specific information regarding
rear panel connections.

Ground Stud
The ground stud on the rear panel provides a point to connect the radio’s
chassis to an Earth ground. This connection is very important for
proper operation of the radio. Do not rely on a ground connection
being made through the rack mounting brackets or other radio
cabling.
Antenna/TX—RF Connector
The
ANTENNA/TX connector is an N-type coaxial connector. When an
internal duplexer is installed, it serves as the connection point for the
station antenna. When an external duplexer is used, it acts as the trans-
mitter RF output (TX) connector to the duplexer.
RX—RF Connector
The
RX (receive) connector is an N-type coaxial connector. It is only
installed if the radio is supplied for use with an external duplexer. It car-
ries receive signals (RX) from the duplexer to the LEDR radio’s
receiver.
When an external duplexer is used, ensure that the higher frequency
(transmit or receive) is connected to the duplexer connector marked
HI
and the lower frequency (transmit or receive) is connected to the
duplexer marked
LO.
