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.
