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

[Mort Arditti]

Joe,

You may want to check the details about braided wire.
The matter is skin effect. As frequency increases, current
flows closer to the surface only, regardless of the wire
diameter. In braided wire, having many wires in the
'bundle' reduces the impedance.
Braid is better than single wire. Flat straps are also very good
because of large surface area and less skin effect problems.
This is the same reason why some RF coils use Litz wire which
is several insulated wires formed into one - just like a rope.

73,
