Tips:
1. If the picture is weak and the antenna boost is working, try moving
the motorhome a few feet forward or backwards.
2. If it is weak or has no picture, check the video selector box to make
sure the proper mode button has been selected.
3. If the signal is still weak it may be a shorted or open coax. The
coax cable is made up of two conductors: A center conductor, (usu-
ally copper) and the ground (woven or braided aluminum). There is
insulating material that separates the two conductors known as
the die-electric. The ground and center conductor are to remain
separate from one another. When installing a metal end onto the
coax cable, use care so that none of the woven ground strands come
in contact with the center conductor. A continuity tester is used to test
for a suspected bad coax wire run. Unscrew both ends of the sus-
pected bad coax run, and use the continuity tester to check between
the center conductor and outside threaded ring. If continuity is pres-
ent, the coax is shorted. To test for an open connection of a par-
ticular coax run, touch each end of the coax’s ground or center con-
ductor using the tester leads. Continuity should be present. For
proper operation there should be continuity from one end to the
other of both the ground and center conductor. No continuity
should be between the ground and center conductor. Though dam-
age does not usually occur from a shorted or open coax cable, pic-
ture quality is compromised.
The motorhome may have been prewired for a roof mount DSS system. The
prewire will consist of a ¾” flexible conduit, which will run from the front
overhead to a spot marked on the roof. A telephone hook-up will also be pro-
vided for Pay Per View accessibility.
The satellite system programming is offered by Direct Satellite Services.
The dish raise or stow function is controlled by the Antenna Control Unit.
Turning the Antenna Control Unit (ACU) ON will automatically turn on the
satellite receiver.
