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.
