Hi, I am trying to work on 160m (also on 80m) from a city lot. I have been reading about half slopers in the ARRL Wire antenna classics B (chapter 7). I have a 50 ft grounded tower available and can run an sloping wire 60 ft (1/4 wl on 80m) then add an 80m trap and more wire to work 160m. Any thoughts about this kind of antenna?... Thanks, Doug, CO8DM
