We recommend using a lightning surge protector in most cases, but particularly if you are installing your signal booster kit in an area with frequent lightning. The outside antenna is positioned high on your building, made of metal and exposed to the elements - very attractive to lightning! We recommend placing the surge protector between the outside antenna and the amplifier unit to protect the amplifier.
The SureCall lightning protector includes a lifetime warranty replacement gas discharge element. Insert the SC-LP protector to the outside antenna cable. Ground the unit and connect to the 2 ft. jumper cable. Then, connect the cable to the amplifier outside antenna port.
This protector is for 50 ohm signal booster systems. A 75 ohm lightning surge protector is also available.
