I was thinking about the radiation from the coax, myself, but
unless you run very high power, not that much of a concern
Reason would be more to prevent stray rf into power supplies,
ect. (rf in voltage regulator circuits can have some very
undesired effects), but the change in the pattern should be
minimal. What DOES concern me, however (I ran one in beacon
service for many years) is that they dont seem to like EXTREME
WEATHER! If you are in a normal location, then it is no problem.
If, like where my 6 meter beacon was located, is at 8,000 feet,
surrounded with winds up to 125 M.P.H., and heavy iceing, then this
antenna will be a stub in a few weeks, at most! Lost 2 of them in 6
weeks , finally brought it down to reasonable location, useing
stealth antenna to hide it. Not the coverage but not replaceing
antennas all the time , either! For what it is, (a vertical dipole),
I'll give the devil its due-- it actually does work pretty well, with-
out excessive claims as to its capabilities! Jim NN7K

If so the manual is on their site

And NO don't add radials for this model -- it is self contained


Except for the beads on the feedline. Ringos are *notorious* for
feedline radiation.
