The Summits On The Air crowd, at least one of whom "runs" up mountains,
has had very good luck with end-fed half-waves. The transformer weighs
next to nothing, and the rest is just wire. Requires no counterpoise,
very ground insensitive since it's fed at a voltage node. Also because
of that, you need no coax, just an adapter between rig and transformer.
The higher you can get the middle [current node] the better, but it will
work very well with just about any elevation on the far end.
For 40, it's about 67 ft of wire, and is a full-wave on 20 and will work
well there. My KX1, when I still had it, had no problem finding a
match. My HOA-Stealth here at home is an 80-10 EFHW strung about 6 ft
high along the top of a wooden fence. Works surprisingly well.
