Dave: As far as running two receivers from one antenna, do what I have done: Just use a TV 2-way splitter; even though you might have 50 ohm co-ax from the antenna and the splitter is designed for 72 ohm, it will not make any difference as far as reception is concerned. 73 Gene, WØQFC Spring Hill, Florida WEB SITE: http://www.w0qfc.com
