Colin:

I had good luck ordering from W7fg. I got his G5RV and some additional
ladder line, which is 600 ohm impedance.

The ladder line is built from two insulated 16 gauge stranded wires, and
the separators appear to be made from notched half-inch black poly
dripline tubing.
When necessary, it is fairly easy to unclip the wires from the
separators, feed the wires through holes, and snap the wires back on the
separators on the other side of a wall. The notches in the spreaders seem
to be made with some sort of punch, as they are pretty consistent, and do
hold the wire quite well. I'd still use a strain insulator at the top of
the ladder line, though...

Is there a commercial source for 600 ohm open wire line? Not the 450

I boiled dowels in wax years ago and once in a lifeime is enough.

Thanks for the reply, Colin K7FM
