- Following the implementation of full digital TV broadcast in Hong Kong, the free TV programme channels operating in the 600/700 MHz bands were migrated to the 500 MHz band on 1 December 2021, thereby freeing up relevant spectrum for provision of high value-added mobile telecommunications services, such as 5G service. As the spectrum in the 700 MHz band was used for television broadcast in the past, the common antenna broadcast distribution system of a building / self-provided antenna of individual households (collectively known as antenna system) may still be able to receive signals in that particular band.
Methods to avoid receiving mobile network signals operating in the 700 MHz band
- Adding a suitable filter (see the diagram below);
- Using a television receiving antenna with suitable frequency band (e.g. receiving frequencies of television receiving antenna ranged from 470 to 694 MHz); or
- Using a television receiving antenna with a suitable built-in filter, etc.
Other Tips for Reception
- Adjust the location and orientation of receiving antenna for stronger reception of TV signal; or
- In some areas with weak signals, install TV signal amplifier to help improve TV reception.
