Incorporated in your TV receiver are the most
up-to-date devices to eliminate interference.
Local radiation however, can create
disturbances which visibly affect your picture.
Proper installation, a good aerial are your best
safe-guards against these disturbances.
RF INTERFERENCE
Moving ripples across the screen are caused
by nearby transmitting or receiving-short-
wave radio equipment.
DIATHERMY
Herringbone pattern and partial picture loss
can result from the operation of diathermy
equipment from a nearby doctor’s surgery or
hospital.
SNOW
Weak TV signals from long distant stations
result in a poor picture and give the effect of
falling snow. An antenna adjustment or
antenna amplifier may be needed.
GHOST
Multiple image caused by TV signals reflected
back from surrounding buildings, hills, aircraft,
etc. can be minimized by correcting the aerial
positioning.
CAR IGNITION
Nearby cars and electrical motors can cause
small streaks across the picture or make the
picture roll.
