At this point, I've got two #hamradio #antenna choices:
1) Rebuild the fan #dipole, taking the load coils off the 80m legs and allowing the ends to fold down and hang towards the ground, and making sure I've got a couple of extra feet/inches (based on band) on each end of each band's dipole for tuning "oopses"
2) Put up an #OCFD, which will also have ends which will need to droop towards the ground.

The reason for these choices is this: I don't have room for anything bigger. I've got room for a 100' (50 feet on each side) dipole, at most. The OCFD would give multiband performance, but I'm not sure if it'll out-perform the fan dipole.

I'd love to have room for a set of stacked loops, but that's a pipe dream at this point, I think.

I'm also considering laying out a ground based #receive antenna to try to avoid some of this QRM from broadcast stations which don't seem to care that they're interfering with every other service around them... but that's another thought for another time.
