Installing a DISH 500 Antenna
4. Assemble the satellite dish as shown below, except do not attach the Y-
bracket or LNBF at this time.
5. Loosen both skew bolts and set the skew by rotating the dish mounting
bracket to align the red mark with the required angle on the skew scale
which you wrote down on page 119. Tighten the skew bolts securely to keep
the dish from rotating.
Once the skew is set, do not try to fine-tune this
angle when aiming the dish.
6. Set the elevation by tilting the dish mounting bracket to align the red edge
with the required angle from page 119 on the elevation scale. Tighten the
elevation bolts, but
do not tighten the pivot bolt at this time.
7. Slide the dish assembly down onto the mast. Make sure the pivot bolt rests
on the top of the mast. Turn the dish assembly so that it points in the general
direction of the satellites, using the azimuth angle from page 119.
8. Thread two RG-6 coaxial cables through the mast, support arm, and
the Y-bracket. These cables should be long enough to run from your
receiver to your LNBF.
Note
: See Running Coaxial Cables on page 133 for cable installation
guidance.
