[Antennas] Chicken band antenna for 10M

Hi All,

I've been offered the base antenna and push-up pole from the estate of a 
CBer here in the mobile home park (free).  I won't even have to take it down 
as the "Park handyman" is going to do that.

It appears to be similar to the "Ringo" line of antennas, a tall (5/8ths 
wave?) stick of aluminum with a small circular ring of aluminum tubing at 
the base or feed-point, perhaps 12 inches in diameter.  I figured that I 
would disassemble it, thoroughly clean and polish the aluminum elements and 
install it to augment my "antenna farm". (roof mounted Butternut HF-2V 
vertical for 75/40M, Alpha Delta DX-EE fan dipole for 40-10M and inverted 
Vee's for 20 & 15 M).  It might be very handy when 10M finally opens up 
again.

QUESTIONS:
1.  How hard will it be to "retune" this for 10M?  It appears that I could 
telescope the aluminum tubing down some to shorten it, but what about that 
aluminum ring?  How do you tune that?

2.  It would be placed roughly 30-36 feet from the Butternut HF-2V and 
perhaps 15 feet from the push-up pole that supports one end of the DX-EE and 
the center of the Inverted Vee's.  I suspect that this will affect it's 
tuning/pattern somewhat, but is it likely to cause problems to the HF-2V?

3.  Apparently this antenna requires no groundplane, the roof is sheet-metal 
and I figured on mounting the antenna just 1-2 feet above the roof-line.  Is 
that likely to cause a problem with this "Ringo style" antenna?

4.  I call it a "Ringo Style" since I really don't know who made it.  I 
haven't been able to get close enough to it to examine it yet, but is this 
style of antenna worth putting up?  I figured on using it when the 10M band 
opens up (come-on spots :) and perhaps even put up a 10M beacon if I can 
find an old CB radio to convert.
