Mast attachment for automatic antenna boresight

A non-boresight mast converter system configured to convert a non-boresight mast configuration system to a boresight mast configuration for automatic angular adjustment of a boresight of an antenna, the mast converter system comprising:

• an automatic boresight attachment configured to cause angular rotation of a boresight of an antenna mounted to the automatic boresight attachment, the automatic boresight attachment being removably affixed to a mounting structure of the non-boresight mast configuration, the mounting structure configured to move up and down on a mast of the non-boresight mast configuration, the boresight device assembly configured to include:
• an input boom configured to removably affix the automatic boresight attachment to the mounting structure of the non-boresight mast configuration;
• an output boom configured to removably affix the automatic boresight attachment to the antenna;
• and
• a device drive train that includes a motor and is configurable to convert an angular rotation of the motor to the angular rotation of the antenna boresight, the angular rotation of the antenna being in a plane containing the mast of the non-boresight mast configuration.
