ASSEMBLY AND INSTALLATION
1.2m System (Ref. Fig. 1.6)
Attach Side Feed Legs and Braces to left and right
sides of Reflector using M6 x 20mm Hex Bolts, Lock
Washers and Hex Nuts. (NOTE: Long formed end of
Feed Leg attaches to Reflector. Short formed end of
Brace attaches to inside of Reflector rim.) Attach flat-
ten end of Brace to Extension Plate, using M6 x
22mm Round Head, Square Neck Bolts, Tooth Lock
Washers, Flat Washers and Hex Nuts. Round Head
Square Bolt Fits on the top of Extension Plate. Tooth
Lock Washer fits between the flatten end of Brace
and Extension Plate, then Flat Washer and Hex Nut.
Attach Side Feed Legs to Support Block using M6 x
20mm Hex Nuts and Lock Washers. Leave all hard-
ware loose.
Tighten and torque hardware securing Braces, Side
Legs, and "U" Clip to Reflector and Support Block to 4 ft-
lbs (5.4 N-m). Tighten and torque M6 x 55mm "U" Bolt to
18-22 in-lbs (2-2.5 N-m).
NOTE: All installations to conform to latest issue of
National Electrical Code.
Ground antenna mount assembly and feed cables in
accordance with current National Electrical Code and
local electrical codes. Figure 2.0 and 2.1 illustrates
typical grounding methods for the ground pole and
feed cables.
Clamps that provide a solid connection between ground
wire and ground source should be used.
Tighten and torque all hardware.
IMPORTANT: Sealing RF Coaxial Connector: The
copper-plated center conductor in the RF coaxial cable,
which connects receiver to LNB, can experience
electrolysis corrosion at the LNB connector. Moisture
and DC current causes this type of corrosion. To prevent
corrosion, apply a moderate coat of silicon grease to the
center conductor and wrap the entire connection with
COAX-SEAL
tape to seal.
