Thanks Master Chief for that good info. :!:

I didn't know A/S bought Avanti, fascinating.

Do you also have the original length spec for the two versions?

:arrow: I don't see why adding a correctly tuned coil would require shortening the radiator, in fact adding inductance should, if anything, require increased capacitance, adding length to the radiator...

- Possibly it was shortened for the new center of the 40 channel band...??? Straighten me out here if I'm
looking at this bass-ackwards.

The new ring made from some 20-year-old American made C0PPER tubing (with a much thicker wall than the crap currently available at Home Despot) is working out great.

The previous owner didn't use the three bolts which hold the bottom hub and, as you can guess, the weight of the coax jerked out the base, tearing out the feedline and unwinding the coil.

I got the S-5/8 because he decided the antenna was junk and gave it away!

I rewound the coil to fit, interesting challenge - resoldering that 6" feed wire, had to retap for a new SO-239 which it needed anyway.

Thanks for sharing the knowledge!
