[1000mp] Braid or strap for ground wire...big question.

Wed, 1 May 2002 23:42:32 -0400

Easy question to answer.
Run cooper strap from a buss bar mounted near equipment to grounding
system (ground rod(s)).  Use mechanical attachments.  Run a separate
#10, or larger, wire from a crimped lug bolted to each "box" to a clamp
on the buss bar.  AES, for instance, sells a good buss bar unit that is
easy to mount and sells cooper strap.
    Better yet, include a cooper plate outside strapped to ground system
that holds protectors for each coax.

    Avoid braid.  Do not "daisy chain" grounding wires from "box" to
box.  Unless the grounding system is part of the antenna system,
resonances are likely to be unimportant.  (I have a pin prick size scar
on a finger where I received an RF zap due to a resonant (second story)
ground system that became part of the antenna.  No blood only a very bad
smell.)
