Altoids Dummy Antenna

Altoids Dummy Antenna Box

Here’s a quick one. In order to tune the shortwave, I need to provide something between the frequency generator and the radio inputs which loads up the line to “look” like an antenna, electrically. 

But the path needs to shielded from RF interference. So how about a conductive box…Altoids box.

Inside is a standardized “RMA dummy antenna” made up of a couple capacitors a resister and a 20microHenry inductor.
