Santa came early... now what do I build the frame mount out of?

Will 1" round (ID) with a 1/4" wall welded to the frame work? (which I have laying around at the garage)

or should I up it to 1.5" square, or even 2" square? (Which I will need to purchase)

Have a look at Breedlove mounts, it what I use and they will hold anything.

I don't know how heavy that thing is but I would suggest a 'heavy duty' mounting method. That also includes the place where you plan to put it. Any screwdriver type antenna builds up quite a bit of momentum when you are moving and that momentum can be a bear to handle.
Best advice I can think of is to look at examples of other installations, see how 'they' did it. Or just think 'big' to start with, you know?

KØBG.COM has lots of pictures of mounts in his gallery and so do Tarheel on their website.

I am planning to weld right to the frame

First plating a section of the unibody rail with 1/4 inch plate steel then welding the mount I build to that
