Hi friends,
While building the switching box for my new receiving array a thought puzzled
me.
I'm trying to be careful with the grounds isolation, i.e. the verticals ground
system not connected to the central box and feedline output through a separate
windings xfmr.
But could be also a good idea to keep the -12VDC of the 14 relays insulated
from the metal box (and the combiner grounds) and thus return only to the shack
through their own multi-wires control cable?
Sorry if this is a trivial question which could let the technicians smile !
Many thanks and best 73
