Chris, K8CRM, brought my attention to this antenna. It seems to be very compact and is getting rave reviews on e-ham. As with all compact antennas, it is probably somewhat of a compromise and I would have liked to see radiation patterns and F/B ratio to know if it is worthwhile to mount it on a rotor.

As we all know, if you want a no-compromise HF antenna and have a checkbook and real estate to match, get a SteppIr.
