Does coax cable need to be grounded
The National Electrical Code (NEC) requires that the antenna mast and the coaxial cable be bonded to the home’s ground electrode system (GES), which is usually the ground rod installed at the power meter and breaker box.
A separate ground rod is not required, and is not recommended..
How long should a ground rod be
eight feet longGround Rod Length Ground rods come in both 8-foot and 10-foot lengths, with 8-foot being the most common size used in residential installations. As a rule, ground rods must be a minimum of eight feet long and should not be cut down.
How do you run wire through floor joists
To run cable through a floor that contains a cross joist, cut a hole in the cross joist in the cavity closest to the cable`s entry point. Then, run the cable through the hole in the cross joist and through 1/2-inch holes in each joist between the entry point and the communications outlet.

What is a grounding block for an antenna
Coax Grounding Block Next, you’ll need a grounding block. It’s a little device used solely to ground the antenna coaxial cable. You can find this properly indicated in the NEC diagram above (the NEC also refers to the grounding block as an “antenna discharge unit”).
How long can you run coax cable without loss
Using coaxial cable increases this distance to 500m (1640.4 feet). For LANs, coaxial cable offers several advantages. It can be run with fewer boosts from repeaters for longer distances between network nodes than either STP or UTP cable.
How far can a Yagi antenna reach
10 milesDue to this more focused beam, a yagi antenna also reaches farther than an omni antenna. As a general rule, the more directional antenna, the farther it can go, with extremely directional antennas able to reach nearly 10 miles. Your typical yagi antenna has a radius of 45⁰.
