One can also look in the Archives. I believe there have been posts from
people telling of their observations at larger stations of what they were
hearing at particular times, and which antenna setup seemed to be the best
performer. The one that sticks in my mine(although the details don't right
now) were observations posted by George K5TR, who has had the opportunity
to have operated in some of the larger 5 Area Stations.
I personally believe that No Two Locations are the same, what will work at
one place will not necessarily work at another. I usually try encourage
someone who is putting up their first Tower/Antenna to try to get to 70
feet if possible, reason: about 1 wavelength on 20, 1.5 on 15 and 2
wavelengths on 10(which at times maybe to high as mentioned by others).
I know for myself here with a single 20 at 132 feet that I am sure at times
that I am not hearing some of the callers. This year I hope to finally fix
that by adding in a 20 at about the 60 foot level, for me the opposite on
15 and 10 these antennas are at 45 and 35 feet, I am convinced that
certainly towards Europe I would benefit from additional height.
I always enjoy these types of questions and the following discussions, they
help to give insight why one may try one thing as opposed to another.
I hope others will post their observations when having a choice of
antennas at different heights.
