Is the 14 foot pole on the roof or ground?  The National Electric Code calls 
for all metal poles pipe systems, , antenna masts to be grounded and bonded 
together to the main electrical grounding electrode. Gas piping is excluded. 
In your case I would envision a coax coming down the exterior wall being 
attached to a lightening arrester outside your window, then the coax would 
feed into the house and radio via the window.  I would sink the 9 foot rod 
directly under the arrester and attach the two together with a number eight 
or six wire if possible.and also run a wire from the arrester into the house 
and fasten it to the cover screw of the closest grounded outlet.  that bonds 
it to the electrical  system.  The coax will be grounded to the antenna mast 
if it is on the roof and fastened to it.  .  If notfastened to the mast but 
using a standoff insulator  then a separate wire can ground the mast and 
follow with the coax down to the lightenen in arrester.
