How to Ground a Ham Radio

How to Ground a Ham Radio. To ground an antenna is to proactively divert and drain the build-up of static electricity during a storm, which can not only create electrical surges, but also attract a lightning strike. To ground your ham radio, specifically, involves using ground radio frequencies (RF) to improve your signal. The key is to the concept is understanding that the air is one part of your power source, and the ground is the other.

Things You'll Need

Basic understanding of AC and DC currents
Grounding rods
Ground bus bar, if needed
Quality grounding wire such as copper wire
Connectors needed based on your particular design

Instructions

Ground Your Ham Radio
- 1
  Understand that the physical ground at your ham radio site must conduct the electricity. If your soil is always dry, be prepared to keep it somewhat moist.
- 2
  Measure the distance from your receiver to the physical ground. Due to the RF wavelength, your ground wire should be no more than 9 feet long for the simple solution.
- 3
  Be prepared for a more complex ground install if you're ham radio rig is far away from the ground.
- 4
  Consult the ARRL Antenna Book (see Resources below) for the proper design of the optimal ground design for your particular situation. A variety of factors will determine its configuration, whether or not you need a ground bus bar, etc.
- 5
  Count on spending money for copper wire materials, as these will provide the conduction you're looking for.
- 6
  Prepare your yard for running wire from your rig's location to the ground spot you choose. It should be clear of a high foot-traffic area, as well as lawn furniture and other impediments. Depending on your situation, you may need to dig a hole for ground rod installation or bury radial wires at a shallow depth for a length as long as your antenna itself.
