I strongly suggest that you buy and study N0AX's recent ARRL book on Grounding and Bonding. What you seem to be describing is also a violation of the National Electric Code. And while you're at it, buy and study the ARRL Antenna Book.73, Jim K9YC______________________________________________________________Elecraft mailing listHome: http://mailman.qth.net/mailman/listinfo/elecraftHelp: http://mailman.qth.net/mmfaq.htmPost: mailto:[email protected] list hosted by: http://www.qsl.netPlease help support this email list: http://www.qsl.net/donate.htmlMessage delivered to [email protected] ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[email protected]
