Yes, a piece of wire will do the trick but you have to take a long piece (maybe 5 meters) and start clipping until you get the desired results (I did it with a RS 2032 scanner) problem is it is limited, I made an antenna with a female UHF connectors and 5 radials (made out of hanger wire) and tuned to 118,2 (plans are here somewhere in this site) and works perfectly It does not look PRO but that way people believes you built it (actually I have 2 of those) and plan on another 4 (two more on my roof and 2 for my business for RR freqs)
