Electricity has been restored to a transmitter that was deliberately set on fire affecting the television and radio broadcasts to thousands of homes.
The fire service were called to the blaze at the site in Bathampton, near Bath just before 6am.
Crews extinguished the fire in three sheds at the site, but the damage caused a power cut resulting in a loss of broadcast services to around 80,000 homes in the area.
The transmitter - which also provides a mobile network service - is owned by Arqiva.
Engineers from the company had to switch off the power supply to the transmitter to assess the damage to the structure.
A spokesman said there was fire damage to multiple feeders, which carry the digital signals between the antenna and transmitter.
