COMMON INTERFERENCE PROBLEMS & POSSIBLE REMEDIES
1. Weak TV Signal
This produces a ‘Snowy’ picture which can be caused if you are too far away from the TV
transmitter, such as in a remote area, positioned in a valley, or if there is a building, hill or other
obstruction blocking the signal.
Each TV transmitter has a defined service area where reception will be good. Beyond that
boundary is a ‘fringe’ area where the TV signal will be weaker and the reception quality poorer.
Remedy
Firstly determine whether you are in a poor reception area. Secondly check the points covered in
Fault Finding .
2. TV Signal too strong
This can produce severe picture distortion like a zig-zag style pattern. This can be caused when
you are too close to a transmitter or picking up strong radio transmissions from another source
such as CB radio. Also electrical interference can cause similar effects (see Interference 4 below).
Remedy
Turn the gain control switch on the Power Pack to ‘LO’. Secondly check the points covered in Fault
Finding.
3. Ghosting
This is the type of picture you will see when the TV signal is reflected from something in your
locality. The ‘something’ may be a local building or landmark. Your antenna is receiving both the
direct signal and the reflected signal from the same transmitter.
Remedy
Try to move to a better position away from the obstruction. Unfortunately it may not always be
possible to isolate Omni-Directional antennas from the cause of the problem.
4. Electrical Interference
The above pictures demonstrate a typical example of electrical interference. This type of interfer-
ence is commonly caused by electrical appliances, such as fans, electric shavers, fluorescent lights.
Other forms of interference can produce a zig-zag pattern similar to that described in Interference
2 which may be caused by inverters, charging units etc.
Remedy
Check the points covered in Fault Finding. In some instances, this type of interference can be
overcome by switching off the relevant appliances.

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 Plugs
It is critical that all coaxial plugs in the system are
fitted correctly. Using the diagram and procedure
described over the page, please check each individual
plug, ensuring it is 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. An
inspection of the cable routing is recommended to
ensure all is correct. 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.
Pinnacle
The pinnacle is essential for the optimum performance of
the antenna and therefore should be in place when
the antenna is in use.
Gain Switch
Situated below the LED light on the Power Pack, this
switch should be set to the normal ‘NML’ (switch
UP) position for general use. The Low setting may be
used when situated close to TV transmitters where
strong signals may be affecting the quality of the
picture. (see Interference2 below)
Red LED Light
Should the red LED on the Power Pack not light, first
try unplugging the cable connected to the Antenna
Dome from the ‘ANT-IN’ socket. If the LED then

illuminates the fault lies with either the coaxial plug or

earlier.
If the LED is still not lit, please contact our office for
further assistance.
Short Hook Up Test
This test isolates parts of your system leaving only the
TV and the Status antenna linked directly together.
Firstly, unplug the coaxial plugs from the ‘TV-FM’
sockets of the Power Pack which will be connected to
a TV outlet socket.
With your TV fly lead, connect your TV direct to the
Power Pack, plugging into one of the ‘TV-FM’ sockets.
Ensure the antenna dome is plugged directly into the
‘ANT-IN’ socket of the Power Pack and switch on.
Tune in your TV for the strongest signal.
If the picture quality is improved the fault lies with
the wiring of the system between the Power Pack and
the TV outlet socket.
Antenna Dome Coaxial Cable
Check the routing of the coaxial cable from the
Antenna Dome to the Power Pack. Check to ensure
there are no kinks or trapped cable or if there are
loops of surplus cable which could be affecting
performance.
When the Antenna Dome was originally fitted and
lowered onto the Mounting Foot, cable may have
been trapped or kinked under the Mounting Foot. To
check, remove the Antenna Dome as described over
the page to see if this has occurred.
