Alternatively Freeview HD postcode checker facility: http://www.freeview.co.uk/freeview/Services/Freeview-HD2
While the Postcode checkers help us to ascertain if a dwelling/ site is with a digital coverage area it is import to note that these systems are based on theoretical coverage mapping which is generally based upon spot measurements within a postcode area.
The final availability of digital services (Freeview) is governed by the local transmitter coverage, availability of services (MUX’s) and a clear line of sight to a suitable digital transmitter in your area.
In most cases only a physical signal assessment / system inspection carried out by an Aerial Engineers can verify if a dwelling/ site is able to receive adequate digital signal levels from a local digital transmitter.
Note: Clients/ Viewers should be aware that signal reception can be affected by local obstacles such as tall buildings, tall trees and the local topography (hills/ dales etc)
