It's not always convenient to set up the satellite dish if, like us, you have to aim it manually, and definitely not while you're moving. Anyway if you're setting up the dish for radio then you might just as well have the television on. However, there is a long forgotten waveband - Long Wave. If you have a LW radio then you can get BBC Radio Four as far south as the Algarve. If it's too much of an expense to buy a car radio with Long Wave and just for Long Wave- and the BBC have made noises in the past about ceasing the LW transmissions - then you might be able to pick up a cheap transistor set maybe at a car boot sale or somewhere.
There is a trick the knowledgeable might be able to explain - though I can't. If you clip a wire, a crocodile clip, to the aerial and let the other end rest on the ground,then that seems to make the aerial more efficient. Like I say acceptable LW reception as far south as the Algarve and maybe all over Europe and North Africa for all I know.
Not much good while you're moving but while you're stationary, fine.
