I think it was an article on a DB-224e or something like that... 73 Mike - N7ZEF

Several years ago, I found an article on the internet about converting the typical 150-174 MHz folded-dipole VHF antennas to 2-Meters. The article had each folded dipole element electrically "lengthened" by drilling a hole at the bottom and the top of each aluminum tubing element, and mounting a small bolt and nut - thus lengthening the overall electrical length of the element and lowering the resonant frequency. Possibly the coax harness was also rebuilt. The article I'm thinking of had nice color pictures and was a very well done web page article. I haven't been able to find this article, using Google and using the terms that I thought would be a good match. Does anyone remember this article and know what the url might be? These antennas often pop up surplus for cheap (often free), and they're very stout. I see in the catalogs that some versions are rated at 120 MPH wind velocity, and have a 6-year warranty! I've just been given one, too, and it appears to be almost brand-new. It would be a shame to just send it to the metal recyclers when I know there have been good conversion articles.
