Well, I never operated from uncomfortable locations like above the tree
line, but my experience with portable antennas has been the same. Short
loaded antennas are not as good as wires. I prefer a dipole that can be
configured as a sloper, V, etc. I have a 33' collapsible fiberglass
pole that has been useful where there aren't enough trees. It's not
really suitable for backpacking, but smaller and lighter ones are available.
