It is hoped that the temporary replacement will return Freeview TV services to more than 90% of households across the area.
However, some coastal and Dales areas in North Yorkshire and County Durham are likely to be among the places where services are not restored by the temporary mast and where further measures will be required.

It will not be known for certain which households will remain without signal until the temporary mast is operational and additional towers will then be built at identified sites to help fill in the “not spots” of TV coverage.
The mast is expected to go live between October 13 and October 19 after Arqiva announced on Friday, October 1, that switching on of the temporary mast had been delayed due to bad weather.
Arqiva CEO Paul Donovan apologised for the delay and added: "We’re absolutely committed to restoring services as quickly as we can, and to prioritising those in our communities who need help the most.”
People over 65, those with disability, and socially vulnerable groups will receive priority help and a new, online hub offering support and information to those affected will be available later this week at bilsdalemast.co.uk
The areas in red on the map are where services may not be restored by the temporary mast.
