4.7 Lightning Protection
CWT stocks in-line, gas-discharge style lightning surge suppressors as primary
lightning protection for their reliability, ease of installation and low cost to the
customer. In-line protectors mount in series with the coaxial cable or telephone
line which provides an excellent solution for a retrofit application. The protector is
grounded through an external ground screw that is attached to the body of the
surge protector. Be sure to take the other end of this ground circuit into
consideration as well.
4.7.1 Antenna Port Protection
Mount the CWT in-line, gas discharge lightning surge suppressor in parallel with
the coaxial cable between the radio and the antenna. Place the protector as near
the radio as possible in order to limit the amount of cable that will be exposed to
either direct or indirect strikes of lightning or atmospheric static charges. Connect
the largest wire (usually #8 or #10AWG solid) to the ground screw on the body of
the surge protector and terminate it to a proper ground (see above). If you have
any question about the quality of your ground system, stop and remedy the issue
before continuing.
