The antenna you describe is 1/4 sloper.  The tower radiates and the
effectiveness is very dependent on the tower, guy cables, mast and beam on
tip. You have to model your installation to see if it a good antenna for
you. Most Caribbean contest stations just use an inverted V 80m and 160m.

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
