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.
