A simple cost-effective method of feeding 100 Ohm antennas such as
Delta loops is to use an odd number of 1/4 wavelengths of 75 Ohm
coax or a single 1/4 WL of 75 ohm coax followed by any length of 50
ohm coax. For 1/4 WL transformers, Rin X Rout = Zo X Zo.
(Several friends are using RG-59 at 1200W with no problems.)
