I am using a 33" HD DTV offset elliptical dish to transmit a signal with 4 small transmitters (placed where the 5 LNB's used to be). Where on the dish do I aim the 4 transmitters to transmit all 4 on the same beam path? I am having a difficult time finding any information on LNB spacing/aiming to determine the beam angles of the dish/focal points etc. Any suggestions? Thanks in advance
