Hi Jim, Did you get any luck with your 80m loop? I am thinking seriously about making one here in the UK. I dont have much of a back yard though but should manage (just) to get 272ft which should be ok for 80m SSB part of band. Wont be a loop as such but a corner fed rectangle at around 30ft. I will also be using the stranded, plastic coated wire which is military spec. The formula most suggest is 1005/Frq Mhz=Lft. Some say add 6%, some say use 4:1 balun, some say no balun, antennas must be the most complicated, but interesting bit of kit in the ham arsenal. Best of luck. Gordon G1NOR.
