Phil Alcock.Pleased that the problem that you had has now been alleviated by switching aerial polarity from horizontal to vertical especially concerning the commercial SDN,ArqA and ArqB multiplexes on Rowridge.

Jenny.London,NW2 7DW.Sounds like the fault comes from your end if your neighbours still receive their reception.You may have to perform a reset procedure,either that or check your aerial connection if this has possibly become loose or disconnected itself by accident.Do you have a direct aerial connection or indirectly via a connection lead from your TV to a wall socket linked to a communal aerial as such ?

Is your aerial polarised vertically meaning you receive transmissions from the Bath relay mast or is it polarised horizontally which implies you receive your transmissions directly from the main Mendip mast.Have you actually tried the resetting procedure beforehand prior to you retuning with and without your aerial in,as it is possible that without this the current programme memory still in your appliance could be corrupting the BBCA multiplex or the BBC channels you implied as such.From the Bath relay if your aerial is vertically mounted the BBCA multiplex is on frequency 25,while from the Mendip transmitter if your aerial is horizontally mounted BBCA mux is on frequency 61.One final possibility could be single frequency interference either on frequency 25 from the Bath relay or possibly but unlikely on frequency 61 from Mendip mast both at your location.

Tom.A difficult one for me to answer to,im not a proper professional myself just an amateur but if manufacturers created two aerial sockets at the back of everyones TV instead of one,then the simple answer would have been one aerial socket for your current sky-plus box and the second aerial socket to connect your Freeview HD with a terrestrial aerial.One other possibility i may suggest if this is feasible is some kind of aerial splitter of some sorts.
Im sure the true pros on here will offer possibly different but equally valuable advice to you,the more the better !

Andrew Healy,Ashford.Too much signal is most likely the cause,either that or single frequency interference at your location in receiving the D3+4 multiplex from Crystal Palace transmitter.Try a set top aerial or a piece of wire or coat hanger,then ascertain the result whether the D3+4 multiplex is playing games or settled as such !

Dave in Southampton.
Is your main aerial polarised horizontally or vertically loft or externally mounted,and is it also a group A aerial (tipped red) or a group W wideband aerial (tipped black).
One possibility could be that the aerial co-ax cable needs replacing if it is rather old as HD broadcasts do give somewhat poor performance on old co-ax aerial cable.
