Hi, I am on the bottom of Churton Park. 

Firstly, which aerial do I need?  23 or 43 or something better?

If we want to keep VHF.  VHF is our backup aerial.  Our main TV is on std Sky dish.  We don't plan on getting a Freeview deck just of yet.  So how do I exactly bridge VHF with UHF?  *Read, first tv aerial person here :)

At preset we have two VHF outlets - the lounge and the master bedroom.  Is that still ok with UHF?  If in fact we want to put an extra lead to anothe bedroom - do I need to do anything more?
