No problem RC. You're right, you can probably use just about anything non-conductive for the ladder line spacing. I've been toying with the idea of using polycarbonate tubing for something really durable. I use Lexan, a polycarbonate, to build enclosures for some of the Elecraft mini-modules. (In fact, I've been prototyping an enclosure for my HexKey all afternoon). I get the Lexan from Home Depot, but all the other plastic supplies from a place called Tap Plastics ( http://www.tapplastics.com/ ). They sell polycarbonate tubing which I think would make great spacers for open wire feedline.
I would like to build a long doublet with open wire feedline from insulated 14 of 12g wire. I think that using this polycarbonate tubing with a spacing of around 6" would be ideal and very durable (and certainly usable for more than QRP purposes). I just haven't yet figured out how to secure the wire to the tubing yet. The plasti dip would probably be ok, but I need to explore some other methods I think.
