[Antennas] CB vertical GP to Ham use

[John]

I had one of those and it worked great on 10M,

   you wont need to add any length,  I think the capacitance hat 
electrically shortens the antenna,  All I did was take my MFJ antenna 
analyzer to the roof,  loosen the top section and slid it down a bit  
till the SWR sweet spot was where I wanted it,  then I just tightened 
the clamp and had fun.   easy peasy
