True on the wire length. I agree about the traps. A very popular antenna
is the zep, which turns out to be a total length of 178 feet. Fed with
balenced line and tuned. Now did you mean 230 feet at the center? Did I
get that right? Anything will work!!! If you can put up a full halfwave
on 160, go for it. Put a counter poize a quarter wave under it, and you
will work the world!!! That will have gain on 80 as well.
