Yes. It is also important to remember that a SAFE installation (from a lightning and power safety point of view) requires that ALL grounds be bonded together, prefereably outside the building. In other words, while we must consider the behavior of our ground systems at radio frequencies, we must also take into account how they behave at power frequencies, and how they will respond to lightning (think radio frequencies). There is a discussion of safe grounding in the Power and Grounding tutorial that is on my website. All pdf files, no cookies required, free download. While it is specifically written for pro audio systems, the same laws of physics apply equally to our ham stations. :) http://audiosystemsgroup.com/publish BTW -- sorry to have missed seeing you at Dayton -- I just completed a cross country move from Chicago to Santa Cruz, and am totally burned out on traveling for at least a month or two. So I stayed home. The good news that I'm now about 20 miles from Elecraft world headquarters! 73, Jim Brown K9YC _______________________________________________ Elecraft mailing list Post to: [email protected] You must be a subscriber to post to the list.
