Apparatus and method for reusing satellite broadcast spectrum for terrestrially broadcast signals

The user position (14) satellite receiving antenna (16) and first frequency receiving a satellite (12) satellite signal. Satellite signal of the satellite signal path (42) and broadcast antenna (16) is line (28) angle of view. Ground transmitter (20) and first frequency of a transmitter to user position (14) directly groove (40) sends signal. To user position (14) placing the transmitter (20), wherein displacement groove (40) and antenna (16) is line (28) is a angle. The wireless groove (40) is big with a satellite antenna central line (28) enough angle; the ground signal of the position (14) is capable of the ground input signal of the antenna, a satellite input signal of the antenna generating, wherein the input signal is less than interference layer. Therefore, and a ground the signal and satellite signal of the common frequency transmission solution, it interference.
