I'm using C-COR catv line amplifier boxes that I found at the scrap yard. These aluminum boxes are weatherproof, have rf mesh seals, and threaded connectors at both ends. Last week they still had a couple of dumpsters of them. If anyone is interested in them let me know off the list. blythe.charles at sbcglobal.net 73, Charles Blythe KD5TKR
