This lighting surge protector can help to prevent damage to your cell phone signal booster system from a lighting strike to the external antenna. This surge protector connects to one end of the cable that is attached to the external antenna. The included 2 ft. jumper cable bridges the gap between the surge protector and the signal amplifier. The surge protector has a replaceable gas discharge element which breaks the connection in case of a large power surge. This gas element can be replaced in the event of a surge. To be effective, the surge protector must be grounded. While this surge protector will help against a power surge, including a lightning strike, it does not include a guarantee.
