Do attic antennas need to be grounded.

The antenna is essentially designed to capture that electricity. But this wouldn t apply to most attic antennas i would think. A tv antenna then there is no need for an rf ground. 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. 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. Yes all outdoor tv antennas should be grounded. Furthermore tv signals are made of electricity.

Check to ensure that the vent tube is firmly grounded before connecting the wire. If it is important should i just tap the coax or is a separate grounding wire needed. Antennas mine are receive only for fm tv and public safety bands will be generally restricted to the attic. Even if you have a newer plastic antenna there is metal inside.

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. For electrical saftey the antenna should be connected to a lightening arrestor and that connected to ground. Will their location in the attic reduce their tendency to build a charge and attract lightning. How important is it to ground them.

However the connection of your antenna coax to various ac operated equipment in this case your converter box or tv introduces the potential of electric shock. There is no requirement to do this for indoor antennas. I found that a firm grounding of antenna mast gave a better reception as well.
