Homer, I just checked on the other forum and the guys over there are still ooin' and awin' about this old boy's new Vector. I doubt seriously I'll get any good measurements from him. The last measurement he sent me he referred to it as being in the ball park. That was reassuring.

Your figures for the radials @ about 102" + may be right. I estimated the length @ 106.8" based on the two elements being 2800 mm long with 3.5" of overlap only.

It might not make much difference, but I also notice that the Vector shown---indicates the hoop is located at the very tip of the radials and not .5" or more below the tip.

I think the natural progression for the taper of your tubing starting at 1.5" and ending with .5" is fine, but it may be the length of each segment that is also critically important to your getting a good match. My Sigma 4 has similar diameter tubing with 9 segments for the main radiator. I think the New Vector starts with a little smaller diameter tubing and has only 8 segments. How does this compare with what you have?

Just like Bob suggested, the mix and length of each section is also likely important to this setup. Here are the segment measurements for my Sigma 4 and not shown is the 88" bottom element. Sorry you can't read the dimensions, I had to resize the image too much. If you really need the info on this image, go to CB Tricks under antennas. It is listed with the Avanti antennas, even though it is from Antenna Specialists.

Good luck.
