I use a 3/4" copper pipe and hose clamp my copper straps to it. That gives plenty of surface area for a low impedance ground. _______________________________________________ _________________________

I use a eight foot length of one inch copper water pipe. I drilled holes in it every eight or so inches and installed #8 stainless bolts with inside tooth locks against the copper. Everything in the

Or put a piece of 3/4 inch copper tubing cbross the back of your desk. you can get conduit clamps to hold it in place. 73, Pete N4ZR Check out the Reverse Beacon Network at http://reversebeacon.net,

Agreed. The topic here is "back of the desk grounding", and in that location a massive copper busbar is a big waste of money. Worse still, it may indicate a dangerous lack of understanding. The plac

Thanks so much for posting the Moto site guide. A breath of fresh air. When there is a group grope debating the number of angels dancing on the head of a pin it is good to use a microscope and just c
Patrick, Ham radio "conventional wisdom" is full of misconceptions, and grounding is one of the greatest. These misconceptions lead most hams to do dumb things that are expensive and wrong. They can
I have two fairly large stations, so purchased two Harger bars. They were the only commercially available grounding system that I could find. I did not want to build something. The Harger kit came wi

Sorry I was unclear. Let me put it more simply. First I am in full agreement with your conventional wisdom comment. Much of the conventional wisdom is not wise. My group grope comment and angels on t
Wide flat strips have low AC *resistance* because of skin effect, but the inductance isn't much different from a round wire. AC resistance is *very important* in applications like RF grounds for comm
Okay. I am going to go out on a limb here and expect to take a beating with the hopes that other people in the group might benefit from my example. I do not have any of my equipment connected to a gr
