Shortwave radios brought the world together long before the Internet, and now the Tecsun AN05 antenna helps maximize your shortwave listening experience. Ideally suited for today"s compact shortwave receiver and fully portable inside its convenient, compact case, the AN05 extends to a full 23 feet and enhances the performance and reception of your shortwave radio beyond that of a typical built-in telescoping antenna. It"s easy to set up and operate, all you need to do is clip it onto your radio"s existing telescopic rod antenna.
