Don, Is the "300 ohm ladder line" you mention actually open or like TV twin lead?

Don't get me wrong, the rotator wire will work, but it will not be as lightweight as one constructed of computer flat cable as the NorCal doublet was. If you want an antenna that will perform just like the NorCal doublet, use any kind of wire for the radiator, cut to 22 ft. on each side and feed it with 300 ohm ladder line. I use the #22 teflon wire offered frequently by N2GO on the QRP reflector for the radiating element, and use either lengths of the same N2GO wire twisted for the feedline or I use the 300 ohm ladder line. The teflon insulation is nice because it does not stick to tree limbs and if tangled is easy to untangle because of the 'slippery' nature of teflon. The antenna is the same as the NorCal doublet, but the wire is different. 73, Don W3FPR Frank MacDonell wrote: > Does anyone know where one can purchase the wire for the NorCal > Doublet Antenna (4 strand computer ribbon wire)?
