The GPS antenna is pre-wired and has a 3 foot cable
running through one of the Heyco
®
connectors.
When deciding where to place GPS antenna, DO
NOT SECURE! After wiring the receiver and initializ-
ing your system, you will need to test the system
(“Initializing and replacing dome” on page8).
Determine location for GPS antenna. It is recom-
mended you place the GPS antenna between unit base
and side edge of vehicle, 90° from rear mounting
bracket, Figure 6.
The recommended location for the GPS antenna is
based on having a level location and a clear view of
the sky. If another location, further from the base, is
desired, loosen the Heyco connector and pull out addi-
tional wire in the base. You must re-wrap and re-tie
the GPS cable inside the dome to prevent interfer-
ence with the LNBF. Failure to do so will result in
malfunction! Tight Heyco connectors when done.
IMPORTANT! The GPS must be located away from
obstructions on roof of vehicle and other obstructions
such as trees, tall buildings, etc. You must have a
clear view of the sky for proper operation.

13. After all base brackets are secured to roof, put
sealant on top of foot and screws. Place base on level-
ing screws located on base feet and install nut and
rubber washer on leveling screw.
14. Leveling the base is done by tightening or loosen-
ing the flange nut under the base, Figure 5.
Use an electronic level to adjust base so there is no
more than +/- 1° off level in all directions. Place
level on base of unit if possible. (If your level will not
fit inside the base plate, place on outside edge.) Level
front to back and side to side. Raise and lower by ad-
justing flange nut under base. After leveling base,
secure inside base with rubber washer, rubber side
down toward base, and lock nut.
