I read this article and was amazed at how much I never knew about how important it is to have earths from equipment and antennas in the correct places. I am also a little confused by what constitues an adequate ground. A "current" or "choke" balun is most commonly used for this. Turn off the high voltage switch beforere moving the person from contact with the source. Connect a continuous bonding conductor between the tower ring ground and the station ground. In most cases, the best approach is to drive one or more ground rods into the earth at the point where the conductor from the station ground bus leaves the house.
I stripped the paint from the pipe and re-attached the grounding clamp and I noticed a reduction in noise from my receiver. The safety ground conductor in your wall sockets should be connected to ground according to this code, and your rig's chassis should be connected to the safety ground. Can you comment on this? The receive noice reduction is very well worth the 1 to 7 dB transmit ineffeciency, as simply adding a linear overcomes the Tx reduction. A typical shack earthing arrangement, very suitable for HF, would use a length of 15mm bare copper water pipe mounted on pipe-clips to the back of the operating table as shown in Fig 1. To stop RF getting back into the shack, you will need a common mode choke.

The result was a quick flash from the associated fuse and the immediate realization I screwed up. When that happens, the last thing you want to do is to invite it inside. B The purpose of using a three- wire power cord and plug on amateur radio equipment is to: But the ohmmeter's needle didn't move even on the instrument's X range! Just a point about the RF earth. This run should be made with a heavy conductor copper braid is a good choice again and should be as short and direct as possible. Despite this, a quiet RF ground needs to be within a fraction of a microvolt of the potential of the surrounding soil.
Early on I worked for a strange and jovial guy named Gary Schmidt, who had a small company called Audio Services Incorporated in Detroit. That will probably not work very well. I read this article and was amazed at how much I never knew about how important it is to have earths from equipment and antennas in the correct places. But you can quadruple that amount when it comes to the earth mat beneath the ground. At other higher frequency and shorter "wavelength bands" however, RF grounds are either superfluous, or even harmful to overall communications performance. I believe it has been mentioned that electrical codes require that all grounds be tied together with heavy guage wire. On the other hand, a choke on the mains side probably wouldn't do any harm as well.
