There have been some changes made in the Traveler. The automatic controller is
no longer available. What they now have is a controller with a knob on the side
of it that you set for the band you want to work.
If you want to use the 20-10m on 40 or 80m you can sort of do so but you have to
replace the center unit of the antenna so it would involve being able to go out
and do this.
They tell me that the antenna is designed to work best at 24 inches off the
ground. The next spot where it works well is at 20ft off the ground.
