The radio is typically used over a range of 146 - 163 MHz (i.e. Ham, Railroads, & Weather). Years ago, the radio shop I work at would buy replacement antennas from a vendor, which were marketed using a cartoon character, who resembled Daffy Duck. Tuf Duck Antennas by Centurion I believe.

Are they still around, or would it be better advised, to buy a replacement through Motorola Parts? I'm open to suggestions......
Thanks,
