in reference to station grounding, i have read keep the grounding
strap
as short as possible and not a multiple of a resonant length on the ham
bands. with that in mind, even if i ground pieces of equipment to
individual
ground rods, won't the complete grounding system be long? in my mind i am
looking around the room and seeing a grounding system being at least 12
feet
long, if i go along the perimeter of the desks (which are in a "U" shape
in
the room.

trying to grasp this in a practical sense. sorry if it is basic and i
am
just not understanding it.

Hi Mike. "Single Point ground"...this means *not* daisy-chaining to a bus
bar behind equipment tables if possible, and connecting each piece of
equipment to one (1) point that becomes the station's single point ground.
*Not* several ground rods from "individual" equipment. After you collect all
the station bonding straps at a single point, then you run to a very close
ground rod. After you hit that first single ground rod with the bus from all
station equipment, *then* you can branch out in a wide and plentiful ground
field that bonds to all your antenna, towers, masts, and last but definitely
not least, a direct low impedance and high current capable bond to the main
AC service ground rod of your home. The RF portion of the ground can
accomodate parallel connections to multiple ground rods in close to the
station if necessary. They must be part of the lightning protection ground,
never separate from it. There are tons of resources for this and lots of
experts here in this group. You can also try this website I built just for
those questions...one of the pages addresses RF grounds from the
transmitter.
