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

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.

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.
