Where do you put a coaxial surge protector?
The surge protector should be installed between the outdoor antenna and the amplifier. Per the National Electrical Code (NEC), surge suppressors should be installed outside your building, close to the point of entry but away from combustible material.
How do I protect my antenna from lightning?
To completely protect your device from lightning, two layers of protection are recommended: installing an in-line lightning surge arrestor and grounding the antenna mast….In this document:

- Summary.
How does a coax lightning arrestor work?
The arrestor provides center conductor protection by introducing a small air gap between the center conductor and the grounded casing. When lighting strikes, a high voltage will be induced on and in the coaxial transmission line.
How do coaxial surge protectors work?
Some surge protectors have connections in and out for coaxial cable to prevent damage that can come from a power surge or a lightning strike overloading your system by sending too much current into your connected electronic equipment, in the same way that the electrical outlets are protected.
Does grounding protect from lightning?
Do grounded weather vanes or antennas protect against lightning? No. A single path to ground is not adequate to conduct the current involved with a lightning discharge.
Why don’t they use lightning rods anymore?
Perhaps it’s because the chance of a lightning strike is, for most houses, quite low. However, most high buildings and other structures do have some kind of lightning protection system incorporated into them.
Is coaxial surge protection necessary?
If you have a coaxial cable line hooked up to expensive equipment, consider a cable surge protector. Surges on these lines can do just as much damage as surges over power lines.
Should you plug coax into surge protector?
Banned. Yes, it is a very bad idea, unless the surge is a part of a whole house system, and uses a Gas Discharge. Surge protectors are very good at causing problems with catv house systems.
What should I look for when buying a surge protector?
A higher joule rating is the best indicator of greater protection. Choose a surge protector with a joule rating at the very least in the 200 to 400 range. Sensitive or costly equipment, such as computers, displays and audio/video equipment, warrants a joule rating of at least 1000.
