     Two suggestions:

1.    Just put up the vertical (and appropriate radials?), connect your RG-6 
extension and try it.  Worst that could happen is low antenna efficiency due to 
mismatch - nothing llikely to burn up; or
2.    Put up a dipole, better yet, a couple/three dipoles for several bands and 
feed them with that same RG-6 you planned on using for the vertical.  Better 
match to your 75 Ohm cable and you get several bands for real cheap.  

BOTTOM LINE:  Don't fret over what to do, just do it and get on the air and 
have fun.
