Television service was restored to homes throughout Oxfordshire after 9pm tonight.
A statement from communications firm Arqiva, the operator of the Beckley mast, said: "All services from the Oxford transmitter were restored by 9.30 pm Thursday following an earlier fire at the top of the mast.
"An evening inspection revealed only limited damage to the structure itself and television services have resumed from the reserve antenna, initially at reduced power.
"Investigations will continue to determine the cause of the fire and assess damage to the new main antenna " Some short daytime interruptions to services may be required to enable this.
"Arqiva apologises for the inconvenience caused to viewers in this area.
