First Claim
Patent Images
1. A method for controlling an antenna mast comprising:
- receiving an electromagnetic signal via an antenna mounted on an antenna mast;
determining a signal quality level associated with the received electromagnetic signal;
comparing the signal quality level to a threshold minimum signal quality level;
detecting a current elevational position of the antenna mast;
raising the antenna mast to a greater height than the current elevational position if the compared signal quality level is less than the threshold minimum signal quality level and if the current elevational position is less than a maximum height of the antenna mast.

Abstract
A receiver receives an electromagnetic signal via an antenna mounted on an antenna mast. A signal evaluator determines or measures a signal quality level associated with the received electromagnetic signal. The signal quality compares the determined signal quality level to a threshold minimum signal quality level. A current elevational position of the antenna mast is detected or tracked. The antenna mast is raised to a greater height than the current elevational position if the compared signal quality level is less than the threshold minimum signal quality level and if the current elevational position is less than a maximum height of the antenna mast.
