Checking you post code for digital reception in the Luton area is a hit and missa afair. Most of the population of Luton live on and around the surrounding hills and as long as you can 'hit' a main transmitter you will recieve digital reception,ie. Sandy or CP.If you are on CP you will not have to change your aerial unless it very old (before the intro' of ch5). If you are on Sandy you will need to upgrade to a new wide band aerial if you have not done so already.
These comments do not take into account poor cabling and in the case of multi dwelling,poor distribution.
You can amplify or, boost, a low but clean signal, but you can not boost a low and dirty signal. Doing so will only increase the poor signal quality.Likewise too much signal power will effectively shut down a digital tuner - the recieving threshold is very narrow.
Most aerials on the luton relay at Farley Hill are wideband and should not need replacing unless faulty. Also remember -there is no such thing as a digital aerial.
Aerials are configured to recieve certain frequencies and it's these frequencies that carry the analogue or digital signal
Hope this helps
