Close the case. Reconnect the battery or power. 8. Connect the two free (and bare) ends of your coil and a bare end of the long wire in a simple twist. The long wire is your antenna. You now have a shortwave radio. Things to Remember: If you are unfamiliar with shortwave, know that it works best at night in the range typically covered by this ...

The length of the antenna needs to agree with the length of the longest radio waves that you want to receive. Shortwave broadcasters use frequencies that are from about 50 to about 400 feet long, and an effective antenna needs to be at least one-fourth of that length — and one-half is much better.
