Mal and other Litz users,
Nice to hear from you Bill and glad that you are still alive to tell the
tale!
This could be the final Litz installment for me - for a while anyway.
As I said yesterday I installed all 8 lugs on the four parallel #12 Litz
wires. Last night I found the DC measurement on two of the wires was about
twice reading on the other two. This was a concern because it could have
meant some damage to these wires occured at the sharp bend of the cable over
a tree limb 50ft up. I re-flowed the solder on the four lugs and low and
behold the resistance of all fours wires measured equal!
I'm pleased with the 0.40ohm AC resistance for the 50/50 loop (including
.22ohms of soil loss). Not sure if it was worth some 15 hours of
construction time build this cable, just to get out another db or so, but a
flexible low loss cable was needed to allow a more thorough evaluation of
soil loss (The Cu pipe is slightly lower in Rac but too ridged for these
tests). I had to wrap electrical tape over the 4 wires, plus 4 spacer cords,
to hold it all to a 200ft long 3/8" polyethylene tube. 500ft of tape was
required!
Bill A
