I read the book Steve recommends, and purchased a new-to-me Force12 C-4XL
(40/20/15/10m) yagi for a very good price. Force12 says it works on 17 & 12m
using an ATU. My TS850SAT likes it on 17m w/o the tuner and pulls it in fine
on 12m. 20-10m uses full length elements and 40m uses linear-loading. It has
been replaced by the Delta4-XL that uses lumped element loading on 40.
Even barefoot with 2 elements/band, it's common to bust a pileup on the first
call, and start pileups of my own. My 72' tower might have something to do with
that.
