DIGITAL SIGNAL
Digital Signal
Are you experiencing break up on your tv maybe its pixelating(littles blocky squares on your picture)this is all due to your digital signal that you have coming in from the main aerial either on your roof or in the loft,their are a number of causes which will not help your digital signal one being location,if your picture is breaking up and your aerial is in the loft its more than likely needs to be put outside either on the chimney or fixed to a gable end or apex.
If it is already on the roof it maybe that the aerial is well past its sell by date and needs to be replaced it may have been up there for several years and quite worn,the digital signal that you have comning in to your tv (flat screen )should be atleast 45db and no mre than 60db if it is higher this also causes break up of the picture and can cross modulate the signal being processed a proper meter test will determine this for you,have a look at this video here to see what the digital signal looks like on an aerial installation in birmingham click here the digital signal needs to be at the correct levels to get the optimal picture quality for your tv,with out the proper equipment it is just hit and miss to be able to get all the muxes correct for digital.
