Lightning Protection

RadioLabs' lightning arrestor surge suppressors are strongly recommended for all outdoor WiFi antenna installations. A small investment in these protectors and an extra WiFi cable will protect your expensive wireless devices.

These lightning arrestors are gas discharge type surge suppressors for a quick response to electrical surges. When the voltage exceeds the discharge voltage, the surge suppressor instantly dumps the voltage safely to ground. They can withstand multiple lightning strikes.

Our lightning protectors are very high quality. The surge suppressors are constructed of an anodized aluminum housing. The connectors have bright nickel plated brass housings with gold plated pins and sockets for long life. These lightning arrestors come with an included wire lug for connecting a copper ground wire between the surge suppressor housing and a solid ground (pole, tower, etc.)

There are two styles available: A bulkhead mount style and an inline style. The bulkhead style is designed to be mounted to a solid surface, the inline style is designed to be mounted inline between two cable connections. If you need an extension cable please see our WiFi cables and connectors
