This antenna has just come to my attention. Like all things ICOM it is expensive. It is meant to cover all HF bands (maybe with a tuner on some frequencies). I have no idea how it performs.
It looks like a Rybakov style antenna, but I have no idea.
There are other, similar commercial antennas around which are far less expensive.
Of course, you can roll your own and save a packet!
