Do you have to ground an antenna discharge unit?

The antenna discharge unit is not to be located near combustible material and certainly not within a hazardous (classified) location. The antenna discharge unit must be grounded. The grounding conductor is usually copper; however, you can use aluminum or copper-clad aluminum if it’s not in contact with masonry or earth.

Is there an antenna discharge unit for a satellite dish?

There is no antenna discharge unit as required for satellite dish installation. Instead, the shield of the coaxial cable is connected to an insulated grounding conductor that is limited to copper but may be stranded or solid.

How is the grounding conductor connected to the discharge unit?

The grounding conductor can be bare or insulated, stranded or solid, and must be securely fastened in place and run in a straight line from the discharge unit to the grounding electrode (Photo 2). If the building has an intersystem bonding termination, the grounding conductor is to be connected to it or to one of the following:

Mar 07, 2014 . UL standard UL 452 covers antenna discharge units. However, at this time (December 2011) there are only three manufacturers that make listed products according to UL 452, and there are no devices that have specific radio amateur applications.

What is the difference between a coaxial grounding block

"The antenna discharge unit (also called a “lightning arrestor”) is connected to the transmission line at a point close to where the transmission line enters the house" So we should install both the grounding block and lightning arrestor near the place where the coax enters the house....

TV Antenna Grounding

The TV antenna discharge unit (also called a "lightning arrestor") is connected to the transmission line at a point close to where the transmission line enters the house. One end of a ground wire is attached to the discharge unit. The other end of the wire is connected directly to the ground rod.

Second grounding rod? And what coax antanna discharge unit

Use either a listed grounding block, which simply grounds the shield (more than sufficient), or a listed antenna discharge unit (which grounds the shield and also adds a lightning arrester for the center conductor). Secure the grounding block to the structure with screws, then screw on the coax cables to both sides.
