ABSTRACT:
A low cost, highly efficient multiband feedhorn mount assembly for co-locating first and second feedhorns on a ground satellite receiving antenna comprises a first mounting bracket adapted to be secured to an antenna bridge for adjustably supporting the first feedhorn. A second mounting bracket carrying the second feedhorn is adjustably attached to the first mounting bracket such that the first and second feedhorns, when attached respectively to the first and second mounting brackets, may be individually oriented relative to the antenna reflector. Co-located transmissions in different frequency bands from one or more satellites may thus be received without the need for a costly hybrid multiband feedhorn. Methods for installing the assembly are disclosed.
