If You Have Done Every Thing Right And TV Still Does Not Work
If you are sure everything has been done properly and you are still getting problems then a booster/amplifier may be the only away to go.There are more misconceptions about amplifiers than any other area in this trade. The crucial point to understand is the difference between signal strength and signal quality.
The only way to improve signal quality is at the antenna, either by changing its location/direction or by using a higher gain antenna. If one has a good quality signal but it is of small amplitude (hence the term amplifier) then an appropriate amp (particularly a Mast head amp) can work wonders for picture quality.
On the other hand, if the signal is of poor quality and one adds an amplifier it will give no improvement all you will get is a large poor quality signal, as opposed to a small poor quality signal! The best example of a poor quality signal is ghosting, but a low “signal to noise ratio” can also give symptoms of low gain (i.e. A grainy picture) or digital picture break-up. The noise referred to is background rf (radio frequency) noise which is around us all the time.
Still Got TV Problems?
If a booster does not solve your problem and you are still getting pixilation and digital skipping of the picture the only options left are:
Try a different antenna something different pick-up or with higher gain
Try the large Hills Spectromax – Try an antenna more specific only to the channels you want to receive (Digital LOG antenna) as you may be getting impulse noise from the unneeded bigger elements on the antenna which are no longer needed for digital.Higher, higher, higher
The Higher the better or relocate the antenna to a different position on the roof. Your antenna may be in an area of convergence radio waves thus canceling out the TV signal. Or the antenna may simply be not getting the signal due to large trees, powerlines or other buildings in the line of site.Remember that too much signal can cause the pictures & sound to break up just as much as too little signal. So make sure your not right next to the transmitter AlsoTry and keep the antenna as far as possible away from TVs, computers and other electrical appliances and fluorescent lights including the compact types.
