Vertical radiators over the earth are optimally exactly vertical. Were
it not so, broadcasters would use tillted towers.

An excercise I`ve performed countless times is microwave path
establishment and optimization. I`ve bolted the tiny dipole feed into
the dish selecting horizontal polarization over vertical polarization in
most cases.

To establish a path, I set the azimuth using a transit and Coast and
Geodetic Survey maps to aim the dish on path. To aim for the horizon as
needed for a long path, I simply use a bubble level on the feed horn.

As soon as the signal appears, optimizarion begins by refining azimuth,
elevation, and polarization for maximum limiter current in the receiver.
Never have I seen any adjustment other than azimuth make any change in
the signal received. Parallel antennas at both ends of the path are
optimum. The same is true with vertical polarization for what is
essentially free-space propagation except for the grazing near the
middle of the path.

Tilt as Art implies it is a myth.

Richard, You are living in the past. Learn how to use a computor
then use it to learn for yourself so that you can be a worthwhile
contributor instead of a book parrot. First proove it for your self
then share findings that you obtain for yourself.Ofcourse that isn't
going to happen
since you don't want to learn how to use a computor because you hate
change.
If Roy is a friend of yours ask him to check it out on his computor
program or
ask anybody who has a computor to check it for you before mounting
your podium.
with silly statements. Why can't you do that vector trial have you
forgotten
that ol;d electrical stuff? Does old age give you enough license to
live a continual senior moment
for days at a time?
