[Antennas] Mosley Classic 33 Balun?

[Don Boyer]

I recently obtained a Mosley Classic 33 antenna that appears to be in
excellent shape.  It has an SO-239 coax connector to the antenna's "Classic
Match".  The Mosley website indicates that for The Classic System:  "To
isolate the outer coax conductor from ground, the coax line is coiled for a
few turns near the antenna end.  This is designed to prevent the very
unlikely effect of Feed Line Radiation".  I have also heard that with the
Classic 33, you can connect your coax directly to the SO-239.

Is this coiled coax actually needed and if so, how many turns, what diameter
is the coil and where is the coil located? (I typically use RG-8 coax)  Any
comments regarding this interface would be greatly appreciated.  The coiled
coax may not even be required. This is unclear to me.

Also, any repair / maintenance pointers would be helpful before I put the
antenna on my tower.  Thank you.
