- \n
- Warning:<\/strong> It is a poor ground for radio signals because the long wires inside your house act as antennas, picking up noise from LED lights and computers.<\/li>\n<\/ul>\n\n\n\n
2. RF Ground (Performance)<\/h3>\n\n\n\n
This is the system that provides a “counterweight” to your antenna signal.<\/p>\n\n\n\n
- \n
- The Goal:<\/strong> To keep the radio chassis at “zero” RF voltage.<\/li>\n\n\n\n
- The Benefit:<\/strong> It reduces “RF in the shack,” prevents your microphone from biting your lips (RF burns), and significantly lowers the background noise in your receiver.<\/li>\n<\/ul>\n\n\n\n
3. How to improve your RF Ground<\/h3>\n\n\n\n
- \n
- Keep connections short and wide<\/strong>. RF travels on the surface of wires (Skin Effect), so a flat copper braid is much better than a thin round wire.<\/li>\n\n\n\n
- Connect all your equipment (radio, tuner, amplifier) to a single copper bus bar, then lead that bar to an external ground rod.<\/li>\n<\/ul>\n\n\n\n

Pro Tip:<\/strong> If you have high noise (QRM) from your house, try to power your radio from a battery for a moment. If the noise disappears, your Electrical Ground<\/strong> is bringing interference into your radio!<\/p>\n<\/blockquote>\n\n\n\n
