I live on a hill (850ft) and tried a discone , a dipole and a 3 ele beam . I
made a few contacts into CA. and southwest with the discone this past June
in one of those big openings.It was up about 15 ft. the dipole didn't work
as well,, and the beam worked as a beam should. I painted about half of the
USA on my grid map with the 3 ele beam. I have a 40m loop up 35 ft and a 5/8
11m vertical I use on 10m believe it or not sometimes I get better receive
sig using the vertical even when the contact is horizontal. I am thinking
about putting up a vertical for the hf bands 160-10m I'll bet in some
situations it will perform as good if not better.

Good point. Maybe I WAS overshooting him. I'll have to
keep that in mind. I usually use a dipole on the
mountains anyway.
