CELL PHONE BOOSTER ANTENNA CODE
For a surge protector to work properly, it's critical that it be grounded properly, otherwise any electrical surge won't have anywhere to be redirected to.Īccording to the National Electric Code (NEC), a surge protector should be installed as near as possible to the point where the cable enters the house, but not near combustible materials. Installing a coaxial surge protector in the path from the outdoor donor antenna to the signal booster protects both the booster and the inside of your home by redirecting any large electrical surge to an electrical ground. To completely protect your device from lightning, two layers of protection are recommended: installing an in-line lightning surge arrestor and grounding the antenna mast. Lightning doesn’t have to physically strike the antenna itself to cause damage: nearby lightning strikes and static charge build-up during storms can also create voltage surges which, although smaller, can damage the filters and amplifiers inside the booster or DAS headend.
Lightning can strike the antenna and travel through the coaxial cable to your device, which will not only damage the signal boosting equipment but can cause a fire or shock people in the vicinity. Grounding the antenna protects your signal booster or DAS from damage in case of lightning strikes. While cell phone boosters and distributed antenna system (DAS) have become an increasingly common accessory for businesses and households, many people are overlooking a vital component of their set-up that will protect their investment and ensure the longevity of their equipment: properly grounding the antenna system.
