lightning protection.

by

Item arrived quickly in good condition. Purchased for tv antenna lightning protection. There are much more expensive alternatives, but TII is a well known brand and I use various products from this company and trust this item over a 2 or 3 dollar grounding block. This should be the most minimal component in your lightning arrest and suppression system.

This is the one you want!

TII makes the only UL listed protectors I've ever found. When I worked for the phone company, we installed TII's telephone protectors. The ONLY time I ever saw surge damage was when they weren't grounded properly.

it seems well made

Feels rugged and looks corrosion resistant. I dont detect any insertion loss. The screw lug easily accepts 8AWG stranded wire. I dont think the antenna has been hit by lightening yet so theres not much to say. If I see a hit and the TV still works Ill update this review.
