Do Attic Antennas Need To Be Grounded

I can tell you that as of the 2004 nec and nfpa 101 which covers life safety codes there is no requirement to ground a receive only internal antenna system.

Do attic antennas need to be grounded. If it needs grounding it can t go in the attic because code requires that grounded antennae be on the edge of the roof and that the wire from the antenna to the ground follow a straight line path or something like that i m not the electrician. But this wouldn t apply to most attic antennas i would think. The antenna is essentially designed to capture that electricity. There is an nec requirement to ground metallic objects in a structure likely to become energized such as metal water pipes appliances gas lines etc.

For electrical saftey the antenna should be connected to a lightening arrestor and that connected to ground. Antennas mine are receive only for fm tv and public safety bands will be generally restricted to the attic. Note that the coax is going to be grounded at the receiver anyway. In the case of an attic installation your tv antenna will be sheltered from the environment so there s no need to ground it for that reason.

Furthermore tv signals are made of electricity. Will their location in the attic reduce their tendency to build a charge and attract lightning. If it is just for reception e g. Even if you have a newer plastic antenna there is metal inside.

Yes all outdoor tv antennas should be grounded. A tv antenna then there is no need for an rf ground. There is no requirement to do this for indoor antennas. If it is important should i just tap the coax or is a separate grounding wire needed.

The copper wire at the base of the antenna mast attaches to the copper vent tube that runs to the roof through the attic in a 55 year old house. Transmission antennas and cables i d have to pull the code books and check but i m fairly certain they do not require grounding as well. How important is it to ground them.
