Ok, folks. Went to the local ham radio outlet, and
the dude said that the polyethelene foam RG-8 isn't very good in terms of
breakdown voltage, which is about 600 RMS, i believe.

However, RG-213 is solid polyethelene, with a BV of 3700 volts RMS.

So i went with the RG-213, and reduced the total turns to 4 (originally 6).

Hopefully this will not melt again.
