  • Page 41: Pointing The Satellite Dish And Connecting The Transmitter

    Satellite antenna alignment is accomplished by first “receive pointing” the dish then “transmit pointing.” When receive pointing the dish is adjusted for the best receive signal. Transmit pointing fine tunes the antenna alignment for the strongest possible signal received by the DIRECWAY National Operations Center (NOC). Transmit pointing is done by certified professional satellite install- ers.
