The second phase of the $20 million upgrading work for the public rental housing estate communal aerial broadcast distribution system has finished, the Housing Authority says.

Upon the completion of the first and second phases, more than 140 estates are ready to receive digital terrestrial broadcasts.

Lung Tin, Ma Hang and Cheung Kwai Estates are not yet able to receive digital broadcasts due to reception issues, and signal coverage at Lai King Estate and one block of Wan Tsui Estate is being fine-tuned.

The Office of the Telecommunications Authority is working on the problem.
