CB attena mounting question for the experts

["Eppinger.Michael" <Eppinger.Michael@domain.elided>]

IH all,
I know there are some CB guru's out there, so here is a question about
the attena mounting.  I have a Terra with a fiberglass top on it.  I
have a magentic mount attena, that I am using with my cb.  I was
thinking of adding a metal "pole" to the rear bulkhead, so the attena
would stick to the top of this pole.  I figure that I would make the
"pole" about the height of the cab top, so the attena would be above the
terra top.  Will this work well, or does this affect the infamous
"ground plane" effect that you want?  Anyone have some input on this.
Is this worrying over a gnat's @ss? or is this a poor performing idea?
