Urgent- No Signal issue

My mum’s TV is not receiving any &/or intermittent signal. She has freeview box not picking up any signal & when switched to TV the signal picks up from time to time. She has a Sky dish on the roof but no UHF antenna. Cable runs from dish through the wall, there is a black cable which is not connected to anywhere. Need someone to look at it urgently. Job is safe to do contactless as it is a big house & occupants can go into another part of the house to keep separate from lounge to outside where job requires access too. Thanks.
