Amateur station rf grounding

Even if you could put an antenna that is feet long, feet above the ground, it would still be only. The earth rods I used were four feet long and made of copper-coated steel. Ground at the antenna end will be whatever the antenna thinks it is, while ground at the receiver end will be whatever the receiver thinks it is. For obvious reasons, the 8-foot buried pole won't work. Lets break down these dimensions in terms of wavelength, and even look at them as they may appear to form a "current loop"! Running ten watts on top band, I've taken regular RF current readings.

How to Ground Power and Radio-Wave Frequency in Your Ham Radio Shack

In figure 3, the antenna, transmatch, and ground system are represented by a simple voltage divider. For decades, amateurs have been advised to bond all equipment cabinets to an RF ground located near the station. RF grounding is as mis-understood and as difficult to understand as "impedance. Note the severity of the problem in some quantitative way so you can tell if the counterpoise makes a difference. The potential is about 50 volts. Avoid solid conductors as they tend to break. Thus the more conductive surface area the larger the path for electrons to earth ground.

Also note that an RF ground may be necessary even if you have a balanced antenna system with a balun for example , because equipment can fail and then RF is driven back to the shack. Based on experience with other peak sensing systems, I estimate that the meter probably reads noise power too high by about 3 dB, relative to the carrier power in the test waveform. All perfectly up to code and okay at 60 Hz, but lousy at RF: They do not buy miles of expensive copper wire and then bury it and pretend that they've scrapped it as some sort of tax loss. Considering all of the uncertainties, the numbers hold together remarkably well, better than the likely accuracies in this case just dumb luck. Statistically however, most lightening damage comes from the AC power and telephone lines running into your home. Actual ground connections to real soil may exhibit resistive impedances in the tens of ohms.

The high current point of maximum signal radiation is at the center of a half wavelength antenna. If you really want to get elaborate, use two or more wires routed in different directions to make up your counterpoise. The station ground must provide both effective DC and RF grounding. My numbers are only representative, but they do serve as an illustration. I would also assume that the antenna is grounded when it is connected to the receiver as the outer braid of the coax is in continuity with the receiver chassis.
