1.3.6 Antenna Connector

The standard Guardian has a 50-ohm TNC female antenna connector. This connection
functions for both transmit and receive.
The Dual-Port Guardian has a 50-ohm TNC female antenna connector functioning for
transmit (only) and a 50-ohm SMA female antenna connector functioning for receive (only).
The separate receive antenna connector allows for unique customer applications that require
additional receive filtering, external PA(s) and other options.
Warning: The transmit antenna port must not be connected directly to the receive
antenna port of the Dual-Port Guardian. Excessive power into the receive antenna
port will damage the radio. Input power to the receiver should not exceed 17 dBm
(50mW).
To reduce potential interference, the antenna type and its gain should be chosen to ensure
the effective isotropic radiated power (EIRP) is not more than required for successful
communication.
