5/8 wave 6m vertical
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. de KJ4UO |
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 -- Caveat Lector (Reader Beware) Help The New Hams Someone Helped You Or did You Forget That ? wrote in message oups.com...

BINGO! And, because it is essentually an end fed dipole, it
does not require radials for a counter-poise. As info, Jim NN7K Caveat Lector wrote: 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 |
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 -- Caveat Lector (Reader Beware) Help The New Hams Someone Helped You Or did You Forget That ?

Ringos are *notorious* for feedline radiation. w3rv -- Caveat Lector (Reader Beware) Help The New Hams Someone Helped You Or did You Forget That ? wrote in message oups.com...

Sounds like a Ringo Ranger

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!
