Abstract
A communications system includes a satellite hub, a remote satellite terminal, and a satellite configured to provide communications therebetween. The remote terminal includes a controller that functions as an enforcement mechanism when adjusting antenna polarization on the remote satellite terminal to facilitate communications with the satellite. The satellite transmits an acquisition signal at a first satellite polarization angle, and a jamming signal at a second satellite polarization angle different from the first satellite polarization angle. If the polarization is not set correctly, then the jamming signal is not filtered by a narrow width null of the receive gain pattern at the remote satellite terminal, and the controller inhibits transmission. This forces an installer to correctly set the polarization of the antenna at the remote satellite terminal.
