I'm looking for about 100-200' of rg58u for a series of quarter wave measurement test heads. Old rg58u pulled from service would be idea. It will just be used for rf current sensing in phased array measurement - not for transmission. So anything 50 ohms will work, I guess. If you have a hunk you want to find a new home for, plz contact me off list. Thanks! 73/jeff/ac0c
