Rick,

With both ants being fairly equal on DX transmit, the advantage of quieter receive
would put the dipole ahead in my situation I believe.
Not really bad but I do have local noise from power lines that come and go.

thanks for the info,
Bob

I have an 80M vertical with 4 elevated radials now.  What is your
opinion on the 80M rotatable dipole
at 105 feet versus my 80M vertical.... (for DX)     105 feet would be

I A/B'ed an inverted vee with 120 degree apex angle
with apex at 130 feet with a ground mounted 1/4
wave vertical with a very extensive ground plane.
On DX signals, it was a toss up.  On NVIS signals,
the vee was about an S-unit better, but a lower
vee was even better than that.  This was for
transmit.

On receive, my experience is that dipoles are
usually better than verticals.  I've never
seen a case where a vertical was better.
