Hi Group,

I have a older 5/8 wave 6m vertical base antenna. It has a tuning ring
down at the bottom for SWR adjustment and it does not have any radials.

Anyone know who the manufacturer and model number?

Also, the fact that it does not have radials an issue? Should I add
them?

The SWR is pretty good.

I suspect you have a Cushcraft 6M 1/2 wave AR-6 Ringo

If so the manual is on their site
http://www.cushcraft.com/support/pdf/951285.pdf

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

BINGO! And, because it is essentually an end fed dipole, it
does not require radials for a counter-poise. As info, Jim NN7K

Very good -- neat antenna -- I have worked 48 states with it -- have Alaska
and Hawaii still need AR and KY (:-)
Some caribbean DX also
Some F-Layer skip but mostly sporadic E

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

Sounds like a Ringo Ranger

If it is 10.1' long, it is probably the Cushcraft 6m 1/2 wave FM
Ringo, rated at 3 db & 1000 watts.

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
