It is VERY possible that the original Avanti is shorter and I got the two mixed up. Now I'm going to have to pull it down and measure it. I posted pictures of the two coils a while ago right on this site!

Avanti Sigma 5/8

Pay attention to the feedpoint with the coil; it is LONGER than the original. Also, the longer base tube is for the antenna with the coil as is the fiberglass insulator.

Note that the ground radials can only ONLY mount in ONE location on the A/S version (above the three bolts)! This is a BIG mistake I see people make with the original versions of the Sigma 5/8; they mount the ground radials BELOW the single bolt.
