Stuart: Yes.

Unfortunately "common sense" with respect to all multiplexes going vertical has not prevailed. Thus, vertical polarisation is only best where reception of COM4 to 6 is not good and where COM7 (and 8 in the future) is to be forfeited or is otherwise not good anyway.

I live in Arundel West Sussex and cannot receive channel/SNWS">Sky news channel 132 on freeview on my Panasonic smart tv or my Alba ordinary tv. Why is this please?

Alan Beale: Freeview services are transmitted in groups each of which is a single signal known as a multiplex or "mux". For this reason it's best if we talk about each mux.

So, from Digital UK, Sky News is on COM5. The full list is here:

http://www.digitaluk.co.uk/industry/Channels/channel_listings

If this is a reception issue then you must be missing Pick and all other COM5 services.

The six main multiplexes are, along with the first service on each:

PSB1 - BBC One
PSB2 - ITV
PSB3 - BBC One HD
COM4 - ITV3
COM5 - Pick
COM6 - 4Music

There are differences in the signals of the COMs vs the PSBs. The coverage of the COMs isn't as good so you may have to go further in order achieve stable reception.

Do you have COM4 and COM6? Also, try a manual tune for COM5 which is on UHF channel 22 (482MHz). Go to the manual tune screen and enter/select this channel/frequency but don't press the button to scan/add services, rather wait and see what sort of quality and strength readings you get and whether they are stable. Having observed for a minute or so try scanning.

Rowridge is unique. Since switchover in 2011 it's been broadcasting horizontally and vertically. PSB channels radiate at a power of 200kW horizontally and vertically, whereas COM4-6 are 50kW horizontally and 200kW vertically.

So turning the aerial for vertical polarisation might solve the problem were it not for the fact that the new quasi-national COM7 HD multiplex broadcasts only horizontally and it's only 24kW.

This, of course, complicates matters. The preference must be to achieve reception of all channels horizontally. If COM7 is out of the question then without question switch the aerial to vertical.

Looking at satellite images and StreetView I would suggest that the trees may be the main cause of any difficulty. The terrain plot suggests you may have clear line-of-sight at 37 miles, were it not for objects on the ground and this assumes increase in the terrain close to you which the plotter hasn't sampled:

If you have no satellite signal, see Sky Digibox says 'No Signal' or 'Technical fault'

If you have other problems, please provide a full (not partial) postcode (or preferably enter it in box at the top right) and indicate where if aerial is on the roof, in the loft or elsewhere.
