You're writing the check, right?
But seriously, since the antenna
mount itself is probably made of stainless, and since the rivets will be stainless, then it's probably appropriate. The mast
wall has a lot more mass than a rivet, so if an aluminum rivet is used, the rivet will give way due to electrolysis
long before the hole in the mast will if a stainless rivet was used instead. My intuition - as an electrical engineer
rather than a mechanical engineer
, is that stainless rivets are the lesser of two evils. You'll still have electrolysis
- even using lanolin, as it will eventually be at least partially displaced, but the effects will be less than if aluminum were used.
As evidence, how often have you seen aluminum rivets to fasten stainless tangs or gooseneck fittings to an aluminum mast? I've never noticed any - the ones in my aluminum Selden mast are certainly stainless, not aluminum.
