A separate split nut can be used to bond the coaxial cable ground to the GES.ĭepending upon the physical constraints, our Splitters (CM-3212HD, CM-3213HD) can be utilized instead of a separate grounding block. The ground block then is connected to the GES using 14 AWG or larger with as short of a run as possible, and again with minimal bends. This is accomplished by using a ground block located as close as possible to where the coaxial cable enters the building. ![]() The coaxial cable that comes from the antenna also needs to be connected to the GES. It can be connected to the GES using a split bolt connector available at most hardware and home centers. The ground for the mast should be as direct and short as possible, with minimal bends, using a minimum of 10 AWG copper wire (or 17 AWG copper-clad steel or bronze wire). If a separate ground rod is used, it must be connected to the GES with a minimum 6 AWG copper conductor. There are other options listed in Section 250 of the NEC, but the GES is preferred.Ī separate ground rod is not required, and is not recommended. ![]() As we move toward 64 radials, diminishing returns kick in and the improvement gets progressively smaller. As we increase to 32 radials, improvement continues. You might consider 65-foot radials if you use the low HF bands. The National Electrical Code (NEC) in section 810 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. If you need a number to start, twenty 32-foot radials will give you a workable system with most vertical antennas.
