1.3.6 Antenna Connector
The standard Viper has a 50-ohm TNC female antenna connector. This connection functions
for both transmit and receive.
The Dual-Port Viper 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 Viper. 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.
WARNING – EXPLOSION HAZARD – Do not disconnect equipment unless power has
been removed or the area is known to be non-hazardous.
WARNING -EXPLOSION HAZARD-Substitution of components may impair suitability for
Class I, Division 2.
The antenna connector is for connection to antennas housed inside of a suitable enclosure.
