I made one of these sleeve antennas for 10M with the folded back shield,
put a KW on it and it arced through the black vinyl.


It's a standing wave antenna. The voltage at the end
of the shield is approximately 20 times the voltage
at the feedpoint. For a KW, that's more than 5 kV,
too much for ordinary coax.
