Installation

Protector must be placed within five feet of the equipment to be protected and at a point in the coax line where the VSWR does not exceed 2:1 to prevent high RF voltages from triggering the unit. If outdoor use is planned, it is necessary to coat thoroughly all surfaces (after attaching coax and ground wire) with a good sealer/protector. It is absolutely necessary to attach a direct earth ground wire to the nut and washers on the cartridge. A short, Building Approved ground connection is essential for proper operation of the protector.
