Question......
Why is it that some people say you need to add a 6" spring to a 102" whip
in
order to match it? Could someone explain this?

I guess it varies according to the mount and vehicle.
In my case, the whip, without spring, was just about perfect at 28.400,
which is exactly where I wanted it to be.
