Homer the only dimensions I have for the gamma on the New Vector 4000, does not agree with what you are suggesting here. However I could be wrong, because all the info I have for the New Vector 4000, comes from Bob's posted dimensions noted below.

Where did you get the dimensions that you posted above?

Did you also change the way the gamma mounts at the bottom too? The picture above doesn't show the full gamma. Earlier I posted a question if maybe the cooper fittings at the base of the gamma could be a problem, in case the matching using the 259b didn't work out as expected.

Another point regarding your dog bone idea. I think I've said this before also. If your new antenna has radials 107" inches long, and you're using a hoop that is 30" inches in diameter, then the radials will naturally be set closer to the radiator vs. when using shorter radials. So maybe your shorter dog bone would be the way you have to go with the longer radials. That would be something you would just have to measure, because Bob did not include that dimension in his post above.
