Thomas,
I have no idea what it contains only that it you don't put it on, the fitting
will leak no matter how hard you tighten it. (My brother-in-law had that
experience.)
A limited amount on the threaded part shouldn't interfere with the "electrical'
part. It should have some sort of sealing function. (I still missing some
"spring" function of the PL-256 to ensure a proper outer connection. Maybe that
could be an improved PL-256 (PL-256-S :). Some type of built -in weather seal
would also not hurt.)

Hans,
Both pipe dope and teflon tape are primarily lubricants to enable tightening
the fittings enough to achieve a seal. The thread dope is a mix of lubricant
grease and microscopic metallic particles to help prevent galling. I would be
concerned about putting a conductive grease in a fitting that needs two
distinct conductors.

Hi Jim,
I was thinking about the "gray" thread sealer that doesn't harden. It
would also be out of the UV-radiation being inside the threads. Should be no
problem, more than cleaning the gook off.
I don't like to "tighten with pliers" when you have a knurled surface on
the nut (or screw for that matter). It's needed for the UHF connector but not
on the N (or TNC) for a proper connection.
