Malarky! While in some rare cases this transformer action may slightly improve a specific frequency's reception, you can bet the majority of the others will be degraded. You would have better luck simply taking the wire and attaching it to the antenna input jack where your hand held antenna attached! Remember, antennas are tuned circuits! For shortwave reception...(1.6 thru 30Mhz) a long wire of arbitrary lenght will generally provide good results, frequencies in our scanner range are quite fussy where antennas are concerned. In fact, a particular lenght antenna perfect for one band will actually attenuate or trap a frequency in another band! Rubber ducky antennas are equally bad on all bands! They are less than unity gain and unless you are monitoring 400Mhz or above, they are all less than 1/2 wavelenght. Moreover, the lack of altitude contributes to poor reception with these antennas. The handheld scanners work better these days with the shorter uhf antennas because of the porcupine effect...that is, repeater towers popping up every 10 miles or so it looks like the hind parts of a porcupine!
