For those that haven't yet looked up the Ultrabeam antenna it's a variation on the SteppIR. It is continuiosly variable across the bands. They are made in Italy and the cost is in step with the SteppIR which isn't cheap. There is one review on Eham so it's not an overly popular antenna just yet.
Have fun folks
