After a bit of sleuthing, I've learned a bit more about the antenna 
itself. I'm still awaiting time in my schedule to call Fluid Motion 
(makers of the SteppIR antenna) to learn specifics. However, in all 
likelihood, the rubber seals at the base of the fiberglass radomes that 
seals the joint between the radomes and the stepper motors and tapes, 
have deteriorated. These will all have to be replaced; they then need 
additional protection from the elements using heat-shrink tubing and 
copious application of UV-resistance electrical sealing tape (Scotch 33 
or 88 tape) and UV-resistant ty-wraps.. It's possible that one or both 
of motor/tape units will need replacement at about $300 each. Assuming 
the worst, that's $600 for new parts and probably another $100 for new 
seals. One radome is lost and needs replacement, but I don't know what 
that will cost. These are not simply tubes because they contain a track 
in which the tapes run; I'll guess $150 but will have a more accurate 
figure soon.

If we choose to sell and replace this antenna with something else that 
covers the HF spectrum form 13-30 MHz, it would have to be a log 
periodic design. Tennadyne is a respected name and an antenna close to 
the characteristics of what we have will cost about $1100.
