Although viewers may be enjoying Freeview before switchover, problems could occur when the signal is broadcast at full power and the signal strength increases. Communal aerial systems are likely to need changing when the cable is old and unable to adequately carry the stronger digital TV signals when switchover happens. Cabling deteriorates over time, and the TV signal could be more prone to interference and loss of service, particularly the further away a receiver is from the aerial, and as the number of homes served by the communal system increases. Digital UK recommends that as a general rule, systems with cables over 30 years old should be replaced.
Property managers may also want to consider changing the communal system where residents want access to satellite services as well as freeview services via a communal system. To minimise the potential for ‘satellite rash’ with the proliferation of dishes on the outside of a building, property managers could upgrade the system to an Integrated Reception System (IRS), that will be able to offer the choice of Freeview and subscription digital terrestrial TV services as well as Sky and freesat to all properties.
