K1VR: This is exactly what I do. Cable TV coax is cheap when purchased
by the roll. Use F connectors. This idea appears as "Six Antennas from
Three Wires, by K1VR and N1RC, 73 Magazine, October 1983, page 10.
Another alternative is to fashion a two wire Beverage out of 450 ohm
brown plastic ladder line, which is what N2NU and WW2Y do. -- Fred
