Hi:
. . . teflon rod, fiberglass rod - tongue depressors cooked in paraffin,
PVC tubing or pipe, wooden dowel(also paraffined) - even no insulators, just
two wires
under tension for 20-50 ft. >>
Some of the insulators that we see at hamfests, lots of them with very
flat ends and no ridges, round square and rectangular cross section (up
to 12 or 14 inches long (some 3 or 4 inches long) although they look like
dipole insulators, were designed to be open wire feed line `spreaders'.
The conductor went along the edge and a 2 or 3 inch wire went through
the hole in the spreader then wrapped around the conductor on each
side of the spreader.
MW stations use these porcelain insulators and very heavy wire to feed
50 or more kw to curtain arrays etc.
