I did a scan for Freeview TV channels from the central tower in Hamilton and received 23 channels. In January 2023 without altering the UHF aerial I rescanned and received the full 28 channels. However, those 5 channels, which includes Al Jazeera, Hope and 3 other channels,disappeared in February or March 2023 without any alteration to the UHF aerial. What's the status of those channels at present? Have they completed making alterations to the transmission there yet?
