My favorite all around travelling/hiking KX3 antenna is a 20 mtr endfed
half wave (EFHW) wire fed with an electrical quarter wave of TV
twinlead. See
http://w0vlz.blogspot.com/2012/06/another-portable-antenna.html With the
KX3/KXAT3 it will load up on 40, 30, 20, 17 and 10.
My 20 meter zepp is light weight and it only needs one support,
especially when deployed as an inverted V. I've made use a large bush
for a support before but usaully I'm familiar enough with the location
that I know whether I'll find a tree or not. If not, I carry along a 16'
crappie pole (cheap, light and collapses to less than 4') and some extra
nylon cord for guy lines.

A wide-range ATU (such as the KXAT3) can turn a narrow-banded antenna into one that covers a full band or even multiple bands, within limits. One general approach is to coarse-tune the antenna's own inductance, then let the ATU do cleanup.
