GROUNDING THE MAST
Remember the metal pole grounding procedure is slightly dif-
ferent. See “Grounding Procedure for Metal Pole Mount” on
page 32.
Note: if you do not use RG6 quad shielded cable (CommScope 5781
or equivalent) you must run a ground wire from the mast base plate to
the ground block and install it and the ground block ground wire onto
a split bolt and clamp nut. Do not install the ground wire on the LNB.
GROUNDING PROCEDURE FOR UNIVERSAL MOUNT MAST
1. Insert the 1/4-20 x 1/2-inch hex-head grounding bolt
through the grounding hole on the mast base plate (see
Figure 39).
2. Install the 1/4-inch star washer, 1/4-inch washer, and 1/4-
inch Nylock nut onto the bolt.
3. Wrap the 8 AWG aluminum ground wire (or 14 AWG cop-
per wire if you pass within 12 inches of masonry) around
the bolt between the start washer and 1/4-inch washer, then
use a wrench to tighten the Nylock nut.
4. If necessary, secure the ground wire using the cable ties
or insulated U-shaped tacks.
5. Route the grounding wire to the radio ground screw.
6. Bend the ground wire with the needle nose pliers clockwise
around the ground screw.
7. Tighten the radio ground screw.

DANGER
• Failure to properly ground the satellite system may
result in severe personal injury or death.
• Do not attempt to ground the satellite system unless
you have the skills to do so in accordance with NEC
code.
CAUTION
• The National Electric Code (NEC) and local codes
require the satellite system to be grounded to the alter-
nating current main earth ground point.
• Grounding the system helps protect against damage
caused by static voltage buildup, nearby lightning
strikes, and power line crossings.
• Failure to ground the satellite system will void your
warranty.
