This is something you do if you have a TV aerial accessible to your home, isn't it?

My flat doesn't have one, or at least no obvious connector for one. The best suggestion I've so far heard is that I could mount an aerial inside the loft and run a cable from there to the TV, which sounds like a lot of money and effort with no guarantee of success so I haven't tried it yet.

I can watch telly quite successfully dangling a coat-hanger out of the back of my telly upstairs.

I have an external TV aerial hanging from my bedroom ceiling, and it provides perfectly acceptable reception. Ceefax goes a bit wibbly in certain weather, but otherwise it's fine.

If you try it, you might be able to return the aerial if it doesn't work, so you'd only have wasted the money on a few metres of aerial cable. Plus, you can hang small items of cutlery from the aerial, as I do.
