Do radio antennas need to be grounded?
Your antenna mount needs to be properly grounded for your antenna to function correctly. Without a solid ground, you’re bound to get high SWR levels and extremely poor performance.
How do you ground a radio antenna?
RF ground. One wire of the feedline connects to the base of the antenna, and the other connects to ground. The connection to ground has to have a low RF resistance, or you’ll expend too much of your power heating the ground. A few radial wires will provide a moderately low loss connection.
What is a good RF ground?
Use buried radials: An effective RF earth or ground system can be created by burying radials. The more radials buried, generally the better. One approach suggested by Les Moxon is to bury between 50 and 100 wires of length up to 3λ/2.
Why do antennas need a ground?
Grounding will eliminate static electricity, as well as protect against energy to the mast if the antenna comes in contact with live electrical wires.
How long can an RF ground wire be?
If you expect your “good RF ground” to eliminate the second harmonic of a 10-meter signal (56 MHz), you need a wire much shorter than 8 feet long. (No, four feet is not much shorter, and would not work.
What happens if car stereo is not grounded?
You cannot operate a car stereo without having a proper ground wire installed in your vehicle’s dashboard. The ground wire will allow your stereo to operate properly and without any malfunctioning problems when your vehicle is on, and the stereo system is activated.
How far can you run a ground wire?
There is a limit on the length of the wire connecting a cable TV co-ax shield to your house’s grounding system. It must be no more than 20 ft long, unless there is an additional ground rod (see NEC 220.100 for details), though I’m not sure if this would be the distance to your main panel, or to your ground rod.

What size ground wire do I need for an antenna?
Ensure the antenna ground wire is bigger than 10 AWG but not as big as the house ground wire. You need a clamp to secure this connection. Ideally, the house ground wire should be around 2 AWG. So, get a clamp that can conveniently connect a 2 AWG wire with the size of antenna ground wire you eventually settle for (8 and 6 AWG are great choices).
