No probs. If you especially need AM. reception for your radio, you will need an AM. Antenna.
Most radio's have an inbuilt AM. Antenna, but you can buy/or make one, up to you what you want most.
AM. Antennas can be just a long wire, but you will need to earth the radio.
NEVER connect an Antenna Earth to the House (High Voltage) Earth.
Use a separate Earth spike, and make sure there is a good contact at the top of the spike.
Use some spray paint to seal/weatherproof the connection, once you have it cleaned and assembled tightly.
You can get an Earth Spike from Middy's or L&H or any other Electrical wholesaler, or pester your local Sparky.
The Sparky may even give you the connector with it.
Or a piece of water pipe 1M. long, driven most of the way into the ground.
Usually steel, because copper won't take the punishment of being driven into place.
