All of my hamshack equipment is on a single outlet.  This has me 
wondering whether a good quality connection between the entry panel SPG 
and the neutral *at the outlet* (it is less than two feet from the entry 
panel) would approach or achieve the objective of helping everything to 
rise and fall together.

Yet other knowledgeable people say that using MOVs in this way is apt to 
*cause* damage.  I realize that this discussion should probably move to 
Towertalk now, but don't want these questions to go unraised, and we 
have a bunch of the right people here.
