A decent aerial and a decent 2 way splitter is more than likely all is needed - id be surprised if any amplification is needed unless your utterly surrounded by a forest in a deep depression - amplifiers are a thing of the past - apart from larger distribution systems but aerial to 2 points is really really unlikely to need any amplification with the strength of the currant switch over
just looked at google streetview of your road - there are no excessive sized aerials installed which leads me to think your in an reasonable reception area before switchover - now signal is more than likely booming in - although I don't know the area at all so I could be wrong - if the aerials were on 20" masts then id be more concerned

try attenuating the signal while the bt box tunes in an attenuator can be purchased from any aerial installers shop or Maplin electronics
Problem with doing this though is that you could attenuate sutton coldfield too much that it wont pick the correct transmitter up and its a fruitless experience
I can understand your frustration as you can't (in my experience of bt vision) manually tune the boxes you have to let it do a full channel scan - SO BLOODY FRUSTRATING - i had a similar problem where a customers was picking up Billsdale as well as emley moor and it refused to rule out billsdale as a weaker transmitter - the aerial in this situation was pointing at emley moor but Billsdale was on virtually the same angle - at least by sounds of it you have 90 degrees of separation
I tried attenuating the signal there but by the time I had put a big enough attenuator to rule out Billlsdale it destroyed emley moors signal too - so unfortunately that process failed
I solved this customers problem by taking the box home tuning it in on my aerial then taking it back
do you have a friend or relative that receives sutton coldfield with no interference from Waltham
nip over - tune it in then bring it back home
this may solve your problem - its a long shot but sounds like your willing to try anything

Ivan Dilks and JB38
if you google the model number 46xf355d it comes up with a TOSHIBA tv that IS full HD
The confusion is that you state its an Hitachi so part of your info seems to be incorrect
So im confused with that
ANY how - Ivan - read my post I have put on several times about too strong a signal (click to the right where it says how many posts ive added - )

I know this is dragging you away from terrestrial reception ---- BUT
if you want to change something consider a HUMAX freeSAT recorder (yes satellite ) they are HD and absolutely FAB
trouble is they're not cheap (about £250 ) and you need a sat dish installing if you haven't already got one

JB38 --- and other people obviously just done a bit of googling andf came across the meaning of
LNA
Some TV's have a built in aerial booster, this feature is called LNA (Low Noise Amplifier) depending on the strength of the transmission signal in your area this feature can be switched on or off within the TV menu. For example, if your signal is strong or that you have an external aerial booster, LNA should be switched off as if left on it may cause tuning problems.
