This shows 600 kv per centimeter:??
The Nov 1996 QST article cites the 1994 ARRL Handbook as stating teflon is good for 1 to 2 kv per mil (thousandth of an inch).
600 kv/cm * 2.54cm/inch / 1000mil/inch? =? 1.524 kv/mil
So I think everybody agrees.

Hello Jerry,

The most conservative dialectic strength I¡¯ve seen for virgin Teflon is around 20KV/mm. ?My 0.1mm Teflon dialectic will be just fine for a qrp loop. ?The upper end I¡¯ve seen on the spec for virgin telling is 70KV/mm...which even means it has a shot at 100w for my 10 foot loop...that would be good fun to try...heh heh. ?;)
