Just as a point of information, stainless steel has a significantly
higher resistivity vs copper: roughly 43 times as much. I one time
lived in a garden apartment and put up a stealth random wire. I used SS
squidding line for strength, and since it was #26, it was practically
invisible from the ground. It worked pretty well for years. However, I
recommended the same stuff to a friend and he put up a very long random
wire with the same line, and he didn't get out at all. I subsequently
learned that SS was substantially less conductive than copper.
Consequently, much of his power was consumed in resistive losses. Of
course, the same is true for thermal conductivity. That's why many
cooks prefer cast iron frying pans and other cookware to SS.

Jon,
I had never heard of Muletape and Googled it, and discovered the
Detectible version with embedded wire. I have built <100W antennas
with the cattle control version in 1/2" size. It has fine stainless
steel wire rather than tinned copper. There are a lot of accessories
for the farm tape such as clamps that connect all the wires at once
and have an eye for rigging.
I think 4 paralleled 22ga conductors would handle 100W with ease, and
the insulated wire would lessen the worry of running over tree limbs.
Agree with twisting 1 twist per foot to reduce sailing in wind, just
as is often done with window line.

Not sure how much power it could handle, I would also twist it so it
doesn't flap around in the wind as much.

Has anyone ever used the Muletape Quad Detectible as antenna wire?
Has 4 22 ga tinned copper insulated wires embedded, so much like
electric control fencing but insulated. 4 parallel wires in a 1/2”
tape with 1250# breaking strength with the 4 wires bonded seems like a
strong lightweight self-supporting conductor for a long dipole or
end-fed. Cheap at $80 for a 3000’ roll.
Polyester has excellent UV resistance. No idea what the abrasion
resistance would be like, but it is designed to be tied in knots and
to be dragged through ductwork and conduit.
