I thought and found in several cases it was up in F with up in height
until last week when an A4S being tuned to CW for FD went the other
way. Perhaps the equipment hoisting the antenna (a boom lift) had
substantial interaction with the beam. A while ago with another
antenna we did find significant interaction with a tram wire support.

Lowering the height of an antenna above ground, such as a beam, will cause the
resonant freq to decrease, increase?
