I, too, recently purchased a 102". I screwed it in and got 2.5+ to 1 across the 11m band. No spring. Got a spring, same thing. This mount was inches from the cab of my truck. So I moved it out on the corner of my bed and got 2 to 1, with or with out spring. My Firestik wouldn't tune down below 1.9 to 1 here either. I grounded and strapped almost what you did. Made a couple of 8" jumpers and still the same. Found a spare 18' Ratshack coax in the garage and hooked it up. I got a tunable 1.2 on the Stik and 1.5-1.7 to 1 with the 102". That's with an 18', 3', and 3' sections of rg59. I can get some marine grade rg8 at work. I'll try to make and run some of that to see what happens.

As far as you jumping between bands, I don't think you can so much with the whips. Take off the spring and try it on 10m to see how the swr does. You may have to run multiple antennas to switch bands if you keep the whip.

The varying lengths of coax to change swr is just tricking the meter. Or so I've been told. But from what I've read this is ground dependent. Poor ground is effected more by this than a solid ground.
