I may have screwed up!

(edit)... go to wal mart and buy a rake or some tool with a F. Glass handle!...

Walmart on Black Friday weekend?^^ ab v c^^^^ ab v c^^^^ ab v c^^

Lowes/Home Depot carries a telescoping fiberglass paint roller extension handle that should work.

Thanks mike. Yes I know the lower loss cable should go to the higher loss freq antenna but, it wouldn't reach. LOL This whole conglomeration is completely temporary for experimental purposes and because I can't shell out the $ for the mast I want at the moment. I think I'm gonna have to go to wal mart and buy a rake or some tool with a F. Glass handle! My problem is I knew that damn metal mast was gonna present issues and I still did it anyways! Ain't it fun being a man?!!

Try a heavy wooden piece inside a piece of ABS pipe.

The UHF antenna should be OK since it is mounted ahead of the metal mast. Regarding the 2-Meter beam, you can mount it with the antenna about 20 degrees off of vertical to minimize any reaction. The antenna does not need to be perfectly vertical to work as a vertically polarized antenna. That's an old trick used on CB for vertically polarized beams.

The mast will only affect the 2-Meter antenna if it is a multiple of the 2-Meter frequency in length. Non-resonant lengths are basically invisible (RF wise) to the antenna. Just think about non-resonant guy wire sections used to support an AM broadcast tower. Same concern; same solution.

True about the end mount antenna however having a large chunk of metal in the same plane as the elements in the 2m antenna is bound to affect the tuning of said antenna and skew the pattern somewhat. Having that same mast in an 11m antenna is quite different than in a 2m antenna. The effects are much more noticeable on 2m. If the antenna had a longer boom and the driver element was further away from the mast then the effect would be less. I tried that with a Cushcraft A147-11 which I had vertical for a few years and then flipped it horizontal. The tuning changed slightly on it however it changed a lot more on a buddies M-squared 2M7 antenna.
