via HACKADAY: An Antenna to Throw You for a Loop

It is one of Murphy’s laws, we think, that you can’t get great things when you need them. Back in the heyday of shortwave broadcasting, any of us would have given a week’s pay for even a low-end receiver today. Digital display? Memory? Digital filtering? These days, you have radios, and they aren’t terribly expensive, but there isn’t much to listen to. Making matters worse, it isn’t easy these days to string wires around in your neighborhood for a variety of reasons. Maybe you don’t have a yard, or you have deed restrictions, or your yard lacks suitable space or locations. This problem is so common that there are a crop of indoor antennas that seem attractive. Since I don’t often tune in shortwave and I don’t want to have to reset my antenna after every storm, I decided to look at the Tecsun AN-48X along with a YouLoop clone from China. Let’s start with the Tecsun.

In the Box

The antenna is not terribly cheap at about $50 or so, but there’s a lot in the box. The business end looks like something you’d wear around your neck. A small box has a switch for three bands — LW, AM, and SW. the two wires coming out of that box form a loop. You can stick the loop to something using a suction cup or a hook. There’s also a little bar that looks like a standard telescoping antenna but it has two plastic clips on the end. You use this to form the loop into a diamond shape with the telescoping rod about halfway.
