Hi, I like the article. One question about feed lines. If coax is 50
ohms and twin lead has 300 ohms. Why is the twin lead consideres less
lossy than coax? I had thought that higher ohms meant higher impedance
and I thought higher impedance means higher loss. Obviously I have not
read the chapter on transmission lines yet ;-), so I may have that all
wrong.

Also, in the article, I liked the part about before 1950, no one even
heard about swr, and that antennas with high swr were working just
fine. But I make 2 assumptions: 1) I'm thinking, even if they didn't
know or care about swr, they still had to cut their dipoles for the
band they were transmitting on. 2) I still would not want to use a 10m
dipole and transmit 100 watts on 80 without at least using a tuner. Am
I correct in these assumptions?
