UPDATE : The power supply that powers this circuit up, is not working, and I have to get it replaced soon.

This is what I for short wave radio station listening with my portable short wave radio. If you know visit this informative page here, you will see why I chose this to be part of my antenna. Another reason is that cable, especially long coaxial cables, can create signal loss, especially cables that have fall off measurements. The 470 uH inductor x 2 is the one way for it help transfer the signal without signal loss. I know this is not an active antenna, but it sure helps with signal losses.
There is a real active antenna called the PA0RDT antenna that uses the same concept as the Long Wire Match circuit.
