Hairspray-can EH Antennas for shortwave and online programs. Small magnetic (H) antennas (Loops) have a good efficiency for the upper bands (20/15/10 meter band) and also in contrast to E-antenna a defined radiation direction.
The build was an experiment to see if a tube receiver could be stable enough to receive digital shortwave radio broadcasts. The tube acts as both an oscillator and mixer, so the receiver is a type of direct conversion receiver.
