Getting an amplifier for your digital TV set is a relatively inexpensive and uncomplicated way to increase the quality of your picture. However you should remember that an amplifier will only help the cause when the TV trouble is related to poor signal quality. In case the local TV stations are far away from your home an amplifier may amplify the signal strength. However if interference is the issue then an amplifier will only “amplify” your troubles and make things worse. Your first step in this case should be to devise ways to reduce interference.
If it’s important to use a splitter then use a powered one and avoid using a passive splitter. Any type of amplifier you use now should have the capacity to adjust the gain. Remember that an extra strong signal will also cause the picture quality to shatter.
Inspect your wiring
Look at the visual evidence of bad picture quality. If there are lots of speckles but the picture is relatively unbroken then your wiring could be faulty. Your T.V needs to be plugged in again and the other audio visual equipment you have should be fitted into a separate power board so that there is very less interference from other electric objects like air conditioner and refrigerators. In case you are unable to solve your digital T.V trouble by these simple steps you can consider logging into the DTV forum which is maintained by the Australian government. If all fails then call in Digital TV Antennas in Melbourne.
