LIGHTNING PROTECTION KIT

The antenna lightning protection kit affords additional protection through the use of an impulse suppressor installed in the antenna lead-in coax cable. In the event of a lightning-derived high voltage surge occurring on the coaxial cable, the impulse suppressor activates, short-circuiting the cable directly to the protection ground. Kit contents (all components required to install lightning protection are included): – Impulse Suppressor – Self-amalgamating tape – 2 x N-type Male crimp style connectors to match antenna cable – Crimp Tool to match the above connectors (RG59).
