Step 4 how to ground your coax cable.
Grounding antenna in attic.
This antenna has all the reception power of an outdoor antenna but features a curved metal frame of reflectors that are designed for fitting easily into smaller attic spaces.
Here are some photos of my roof top antenna with a grounding wire in the attic.
Clearstream 4v hdtv antenna.
The ge 33692 attic mount hd antenna is a notable example of an antenna specially designed for placement in the attic.
There are very specific requirements for grounding an antenna both via mast ground and a shield ground.
The coax cable itself can build up a static electric charge and in order to properly dissipate that charge an antenna discharge unit or grounding block can be used again check you local code rules.
To bond a grounding wire to the antenna mast you can use either a ground strap or pipe clamp.
Air movement in your attic should not pose a problem.
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.
It might not but there is going to be a whole bunch of electrical wiring in the attic as well for the lightning to follow.
Most people use a galvanized steel ground strap such as this one.
An alternative is a pipe clamp which is heavy duty and made of steel with serrated adapters.
Check to ensure that the vent tube is firmly grounded before connecting the wire.
Grounding a tv antenna isn t just for safety.
Exterior antennas must have their mounting rod grounded to provide electric discharge in the event of a lightning strike or static accumulation from other causes.
The layer of plywood would tend to block those.
Neither apply to an antenna in the attic.
Now it s time to ground your tv antenna s coax cable.
The mounting rod is insulated from any of the active reception parts.
