The message
from The Natural Philosopher contains these words:

Plug a TV in and wiggle the aerial until you get acceptable signals on
all available channels.

You can get a good start by taking a map reading to the nearest transmitter
http://www.bbc.co.uk/reception/trans...ns/index.shtml
and use that to get an initial aim. In my experience this is often enough.

While you're up there, check the connections in the aerial terminal box
- they're often rather narsty.
