Is there any advantage to tilting a beam antenna up or down to match the
anetnna's elevation angle of maximum gain to the angle of the received
signal?
Ron, I have a 12 element Yagi for TV (Horizontal) at 529 MHz and I find
tilting it down by about 10 degrees improves the reception by a
noticeable amount. The ground also slopes downhill by about 12 degrees
too (in the direction I'm looking). Putting the Yagi up higher is not as
good as having it about two feet off the ground with the downwards tilt.
The station is about 100 km away and the signal has to "bend" over a
range of hills 40 km from my location.
