Some time ago, I posted information about using a spectrum display for
RFI tracking. One issue that arose was how to use a short vertical
antenna (~48 inches) as a broad band antenna. In order to do this, a
high impedance, broadband amplifier is needed. Larry Benko, W0QE, has
developed such an amplifier. He describes the amplifier and its use on
his web page:

Check it out.
