Surge Voltage Protection Adapter
for Mobile Phone and Radio Link Systems
COAXTRAB
Sta y on the air with COAXTRAB . For the connection
of antennae in transceiver systems with F or N
connectors, COAXTRAB offers ideal surge voltage
protection. Thanks to the good impedance matching,
high transmission capacities of frequencies up to 3
GHz are no problem.
As coarse protection, there is a replaceable gas-
filled surge voltage arrester in the CN-UB-280DC...
adapter housing. In the case of a fault the surge voltage
arrester can be remov ed b y unscrewíng a scre w in the
housing and inserting the replacement CN-UB-G1 gas
arrester.
The protective adapter can be mounted permanently ,
in the switch cabinet, for example, with the CN-UB as-
sembly board.
