![]() "tom" wrote in message . .. snip One thing to remember is you generally do not want elements that are electrically connected to the boom. The connection is usually not very good and eventually corrodes. This makes the antenna detune in an unpredictable manner. That said, you can weld elements to the boom, which works. You are better off using insulated elements with inserts in the boom holes such as Delrin. This will change the correction factor, but that is a known. tom K0TAR At the moment, my driven element is 664 mm of half-inch copper pipe, my favorite medium for VHF/UHF antennas. I made some antennas for the RACES station at the local firehouse about fifteen years ago and they're still up there. If I were to continue in that vein, I could weld (torch solder, really) the elements to a longer piece of copper pipe. I have seen the "known" correction factors referenced in vague terms, but nothing that I ever got my arms around. Where should I be looking? "Sal" (KD6VKW) |
