Thanks for the reply and sorry if I hijacked your thread a little to show you a point. Explains everything but the potential problem for the mast beside the radiator. Example of a similar problem mount I had with a homemade 1/4 wave antenna not allowing me to tune the antenna even though it was a small infraction.

When I tried to use this setup and keep the ground plane close to the feed point, the approximate 4" of swaged lenght on the end of the support mast that you see next to the base receiver for the 1/4 wave whip was too long by about an inch and prevented a tune with the antenna. See the simple solution in the bottom image where I cut off about an inch. This allowed me to get an immediate tune with just a simple cut using a hacksaw.
