Method and apparatus for receiving dual band signals from an orbital location using an outdoor unit with a subreflector and additional antenna feed
First Claim
1. A system comprising:
- a first satellite at a first orbital slot having a first transponder generating a first downlink signal at a first frequency and a second downlink signal at a second frequency;
an outdoor unit comprising,a support structure;
a reflector coupled to the support structure and reflecting the first downlink signal and the second downlink signal;
a first feed coupled to the support structure receiving the first downlink signal;
a second feed coupled to support structure receiving the second downlink signal; and
a secondary reflector reflecting the second downlink signal to the second feed.

Abstract
A satellite system 10 having a first satellite 14 at a first orbital slot B has a first transponder 32 and a second generating a first downlink signal 44B at a first frequency and a second downlink signal 44C at a second frequency. An outdoor unit is directed toward the first satellite 14 and includes a support structure, a reflector 64 coupled to the support structure and reflecting the first downlink signal and the second downlink signal. A first feed 66B is coupled to the support structure and receives the first downlink signal. A second feed 70A is coupled to the support structure and receives the second downlink signal. A secondary reflector 72 reflects the second downlink signal to the second feed 70.

37. An outdoor unit comprising:
-
a support structure; a first reflector coupled to the support structure and reflecting a first downlink signal from a first satellite along an axis, said first reflector reflecting a second downlink signal from the first satellite along the axis; a first feed coupled to the support structure along the axis receiving the first downlink signal; a second reflector coupled to the support structure not along the axis reflecting spillover from the second downlink signal; and a second feed coupled to support structure receiving spillover from the second downlink signal.
