Hi, the plastic TV aerial on the roof (a fairly flat round disk, a bit starship enterprise like) has perished. The TV wiring I inherited seems a bit jumbled, with some lose coax wires in the cupboard to the right of the stove, and a fuse box labelled 'TV amp fuse 2A'. Before I start removing the existing aerial on the roof and leaving a hole; which will be above the middle of the bedroom ceiling, I'd love to know if it's easy to replace the coax so I have options around what replacement aerial to use. Also interested in whether I could run some sort of 4G or MiFi aerial out the same hole.
Any advice or guidance appreciated.
