This lightning surge protector can help to prevent damage to your cell phone signal booster system from a lightning strike to the external antenna. The surge protector is installed in-line between the external antenna and the amplifier, and then the 2 ft cable is used to connect the protector to the 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.
