Channel Master TV Antenna Lightning Surge Suppressor – F-Type Coaxial in-Line Protector for Digital HDTV Antennas, Weatherproof, Low Loss, Protects Equipment from Power Surges

well made. I bought it because I did not know that the Channel Master preamp1 has one built in already. Channel Master suggested using this between the power injector / splitter and TV for double protection. Really well made.

Be sure to ground the thing this plugs into.

After having my Antenna port blown on my Visio TV, the will protect my new tuner. Low loss and easy installation make this a recommended product.

High quality item, hope it never has to do what it is meant to do. No one likes a lightening strike.

Figured I would gamble and take a chance to protect my TV from a possible lightning strike through my external antenna 📡

Easy to set up and use, just unscrew the transformer from the antenna and screw this in between it and the coaxial cable. Then in the house put it first coming out of the wall before running the cable to your TV

Easy to install, very low insertion loss and protection from lighting infused surges. Just one part of a antenna system.

I installed it to protect my antenna booster. Everytime we get a little storm, it burns out my booster on my outside antenna. After the install it made my signal weaker and I lost a half dozen channels. So I removed it.
