C.2 Antenna Cables
The 14201, 14203, 14205, 14221, and 16755 antennas require an antenna
cable; either (1) the COAX RPSMA or (2) the COAX NTN with surge
protector. Indoor omnidirectional antennas are either supplied with an
appropriate cable or connect directly to the AVW206.
C.3 Surge Protectors
C.3.1 Electrostatic Issues
Many installations are out of doors and therefore susceptible to lightning
damage, especially via the antenna system. Also, depending on climate and
location, electro-statically charged wind can damage sensitive electronics if
sufficient electric charge is allowed to accumulate on the antenna and cable.
To protect against this CSI offers the Item # 14462 Antenna Surge Protection
Kit.
The COAX NTN-L cable is a low-loss RG8 coaxial cable that requires the
14462 surge protector in order to connect to the AVW206. The RG8 / Antenna
Surge Protector are recommended in preference to the COAX RPSMA in the
following applications:
