I'm doing something similar on my current project.  The difference is that 
I'm replacing the box cover with an aluminum bulkhead panel.  I intend to 
use Polyphaser bulkhead arrestors and didn't want to worry about Cu/Al 
oxidation.  I'll still have an aluminum/copper junction between the 
bulkhead panel and the ground system, but I'd rather have 1 per system, 
than 1 per coax & rotor cable.

Industrial Communications, offers Al bulkhead 
panels in a variety of sizes.
