Can someone please describe the physical structure of a J-pole? Wondering
if it's something I can create?
Thanks.

:i know the 300 ohm twin lead is hard to work with, but give it your best

: The reason being that the twin lead keeps the pair of wires an exact

: your using is perfectly straight and without kinks, then you might be able
: to make a j poll with just straight copper wire.
: 300 ohm twin lead is such that the wires are also the perfect distance
apart
: for a particular j poll design.
: If you alter this spacing, you'll end up with allot of headache, even more
: then working with the twin lead.
: I found a very new utility knife works quite well with the plastic of the
: 300 ohm twin lead...a bit tricky to to strip it sometimes, but once you
: experiment on a spare piece, you'll get the hang of it.
