Bushmaster,
You're getting into that 'isolate/insulate' thingy here. Electrical tape will insulate the antenna from the mast, but it won't 'isolate' it. Best 'isolator' would be distance to reduce any capacitive/inductive reactance between antenna and mast. Convert that 'distance' to a longer insulator (non conductive mast?). How long? Whatever you can manage without breaking the bank and is still reasonable/practical electrically and mechanically, sort of. After that, you are 'stuck' with whatever it happens to be. While it ~can~ be, it doesn't necessarily have to be a 'big deal', and you won't know till you try it.
Half the fun of it is in the 'doing', not the results...
