I'm not necessarily taking issue with Dr R. I'm suggesting an
alternative way to fix the problem. Getting rid of the coax
shielding doesn't get rid of the transmission line, but it certainly
does change it and this may be enough to "fix the problem".
BTW, RG8 is 50 ohm cable and the dialectric is PE not foam. 75 ohm
cable typically uses foam to get the higher Zo.

gain. The networks you spoke about would need to take the ~ 300 amp
at 2 X voltage and sink it.
I'm not sure I believe this. If terminated correctly, the coax can
not reflect and there is no voltage doubling at the terminated
end. The frequencies are much higher than the Fo of the coil and
only the initial HF energy coming down the coax to the terminated pig
end needs to be dissapated in the termination resister. If you allow
run away to occur than maybe the high levels you speak can happen.
