The Digital Antenna System
The Status 550 Digital Antenna System
Operating The System
Firstly determine the approximate location of
the nearest transmitter and whether the signals
are horizontally or vertically polarised. For
assistance ask your site operator or check other
antennas in the vicinity.
1. Loosen the mast locking collar and raise
the antenna.
2. Determine whether the TV transmissions
are horizontal or vertical and position
accordingly.
3. Switch ON the amplifier and the LED will
illuminate and check the gain is set to MIN
by rotating the button anti-clockwise.
4. Rotate the antenna:
• RED - poor signal - keep turning.
• YELLOW - getting better - slow down.
• GREEN - signals located, ready to go.
5. If there is no GREEN increase the gain and
repeat the 360 degree rotation.
6. Once the transmitter has been located,
increase the gain to MAX.
7. Turn on your TV set and tune in. This will be
necessary at all new locations.
Fault Finding
The following are some of the key areas we
suggest you check which generally solve the
most common problems encountered with the
operation of the Status antenna.
Coaxial connections
It is critical that all connections in the system
are fitted correctly. Using the diagrams
and procedures described, please check all
connectors ensuring they are wired correctly.
Secondly please ensure only quality plugs have
been used.
Coaxial Cable
Sharp bends, kinks and hot surfaces can easily
damage coaxial cable and should be avoided.
Coaxial cable, if placed in close proximity
to electrical cables, transformers or other
pieces of electrical equipment, may pick up
electrical interference causing picture quality
to deteriorate, especially in poor reception
areas. Excess cable should be removed and NOT
coiled as this may cause picture distortion. An
inspection of the routing of the cable is highly
recommended to ensure all is correct.
Gain Control
In normal use the button should be rotated
clockwise to maximum. In strong signal areas
the amplification may need to be reduced. To
reduce amplification, rotate the button anti-
clockwise until picture quality improves. The
button rotates through 270° from MAX to MIN.
