This kit gives you the two components you actually need to protect a 50 ohm signal booster system from lightning damage: a wideband coaxial lightning arrestor and a 2 ft ultra low loss jumper cable to connect it to your amplifier.

The lightning arrestor installs on the cable coming in from your outdoor antenna. If lightning strikes nearby or a surge travels down the line, it redirects that energy to ground before it can reach your amplifier. The included jumper cable connects the arrestor directly to your system’s input, which is a required step most people miss when buying a lightning protector on its own.

This kit is designed for any booster system installed in a building that ever experiences thunderstorms — which is nearly all of them. It works with all major 4G carriers and supports 5G frequencies up to 5.8 GHz. The arrestor is built for indoor or outdoor use and includes a replaceable gas discharge tube and grounding screw. You’ll need to supply your own ground wire if grounding is required.

Whether you're setting up a home system or a commercial install, this small add-on helps protect the most vulnerable part of your setup: the coax line coming in from outside.
