For my purposes it will primarily be for 80m/40m so an 80m full wave is in the works. I wanted to do two wavelengths for a 160m full wave, but hanging it will be problematic due to the density of trees here. 80m regional is most important so lower won't hurt me that much. I'll be doing a delta horizontal due to the supports I have.
Trying to avoid the temptation of an amp, so far I've done well. The guys with the loops have a bigger signal on 75m than the dipole users it seems so if I can pick up a bit more from a loop vs my dipole, it would be useful.
All it takes is a spool of wire and a good arm with a fishing pole to get them in the trees ;-)
Antennas are more fun(educational too!) and a heck of alot cheaper than an amp.
