    Repurposing rubber duck antennas for projects

    Wanting to see what was inside, I used a utility knife to cut off the insulation on the rubber duck antenna that came with my BC125AT. Can this antenna be repurposed to build a multiband scanner antenna: a standard "ground plane" type or half-wave dipole?

    I have installed a Discone antenna on my roof. Am I supposed to earth ground the mount frame on the antenna? The mount is a TV antenna mount if that matters.
