I dunno about that. I'd never heard of them before, so I did a quick
Google...it looks like it's just a 31' wire supported by a fiberglass mast.
I would reckon that it would work as well on 40m as any other 31'
wire...add a couple feet of wire and it would be resonant on 40. Yes, a
good ground is required, but that's required of any 1/4 wave vertical. I
think with 30-40 quarter-wave radials it would be a pretty decent DX antenna
for 40m...I know my Butternut HF2 was, and it was even shorter. Of course,
any 1/4-wave wire would be as well - the advantage I see of the S9V is that
it's self-supporting.
