Default Mounting Stainless Steel to Aluminum

I will be installing several stainless steel brackets on a newly installed aluminum radar arch. Should I install my stainless VHF antenna brackets with a piece of thin rubber between the bracket and aluminum arch. I intend to use stainless steel screws that will be taped and threaded into the aluminum arch. I want to do it right the first time! Thanks

Midnight, they are two unlike metals,the aluminum will react and oxidize. Whenever the two will be in contact with each other(such as threads) you should dip the screw threads into zinc chromate before assy.
The bubber is also a good idea,but I would use something stiffer, like plastic or teflon or polyurethane. I think the rubber won't allow a good rigid mount.

Put a little teflon type on the threads plus a little never sieze. Anything you can think of will help.

Ditto ! I've also used heat shrink tubing and nylon washers with excellent results.
