Tilt angle

[kq6qv]

If the horizon (including the tree tops) is a few degrees above horizontal, you will benefit from tilting the antenna up to point at the horizon, although for low-gain antennas this benefit is insignificant.

If your visible horizon is many miles away, this signal might arrive at different elevation angles on different days. Some authors will recommend a tilt motor so that you can always maximize your signal strength. But this author believes that high-angle days are always strong signal days and the minor improvement in tilting the antenna up is not necessary. This author recommends a tilt motor only when a rotor is employed and the horizon angle is different in different directions.
