Default LADDER LINE SPREADERS

Hi, Folks.

I need ideas for CHEAP and uv stable, strong, light weight, waterproof
ladder line spreaders of about 4 or 5 inches wide. Wood in any
configuration will not do. PVC pipe will not do. Welding rod would
do but it is expensive.

I was thinking of Fiberglas tape, twisted and put in place and then
resin applied but that is very cumbersome.


These might not be regarded as cheap, but they are designed for purpose:

inches wide, the seller claims about 450 ohms using 2mm diameter bare wire.

If you used insulated wire, Zo would be a little higher (eg 1mm conductor
would give somewhere between 500 and 600 ohms).
