[TenTec] Re: grounding, station plug in protection

[Stuart Rohre]

Rich,
Depending on where you are in the lightning belt, and how long you had those
surge protectors, it is highly likely their operating voltage threshold had
changed over time from other surges, and could not protect at the original
design voltage level.  Particularly, MOV type devices are subject to this
deterioration.

Gas tube devices using helium will have the helium leak out over time,
through the glass itself, and this likely will happen to neon or other
gaseous charges in essentially spark gap devices.  Then you are left with
only a spark plug albeit some types such as the DALE breaker panel gaps also
include a magnetic coil to suppress the arc by back emf once a discharge arc
commences.  This is known as arch quenching, and is good to have.

Bottom line however is as Scott mentioned, have everything as a plug in that
can be unplugged when not in use.

A single panel for antennas, and phone lines could have a pluggable module
designed, and use of a heavy duty outlet strip makes quick work of
unplugging AC to computer, peripherals, 100 watt rig, and accessories.

The single point disconnect plug module would be a great T Kit project!  It
ideally would include AC power to the shack.  But even a single plug in box
that would make up all coax, balanced line and phone connections would speed
"Safing" a station after operating hours.  I think patch panel companies
already have the basic patent on this, but if not, it was my idea! :-)
