Ground anything you do to the house ground as well.
Experiment: drive in two temporary ground rods (can be short ones) a short distance apart, set your voltmeter on AC, and measure the voltage between them. Most of the time you'll come up with a quarter volt or so, just from stray AC power ground differences. If lighting hits somewhere nearby, it's thousands of volts. So you want one ground system, not two. Otherwise all the current that goes with the voltage difference comes inside your house on its way to wherever it's going, by way of your radios. MFJ has a virtual ground box, that produces an RF ground at the end of a long wire, but you have to tune it for each frequency. I don't know that it matters if you're not transmitting. -- Ron Hardin On the internet, nobody knows you're a jerk. |
