Hi John,
Make the antenna feed with 450 ohm flat line. You will have a great
all-band antenna. (use the stranded kind for flexibility). I had one
a few years ago and it always tuned to almost 1:1. Now I have an 80m
one, and it's not as good and doesn't want to tune 160. Next spring
it goes back to 160 m length. You have to use a tuner.
BTW, my tuner has a BIG transformer to go from 50 to 450-600 ohms
out. You have time to look for a good balanced tuner, or make
one. Start reading up.
Do you need an antenna manual?
73, John
