Methods and apparatuses for performing predistortion on transmissions to antennas are disclosed. In some embodiments, a method includes obtaining a type and scan angle of a flat panel antenna of a satellite terminal; selecting, based on the type and the scan angle, predistortion to apply to a signal to be transmitted to the flat panel antenna; applying the predistortion to the signal; and transmitting the signal to the flat panel antenna of the satellite terminal.

Monodirectional antennas may be arranged to radiate in a near omni-directional pattern. By incorporating switches into the antenna arrangement, the antennas can be controlled to selectively radiate from a common radiofrequency feed. These arrangements may be packaged in a housing, which may aid both in antenna performance and in antenna installation. According to another aspect of the disclosure, housings may include a plurality of antennas, and one or more procedures may be implemented to determine a codebook to radiate from the circular arrangement according to various beam constrains.
