Yes.I confirm that it is possible.
 
Unfortunately I haven't seen much interest and have not pursued for 40M. I  
have several fractal designs that would fit in that turning radius, roughly 
5  dBi and better than 20 dB F/B.
 
Someone mentioned a Moxon...too big. Hex's are also too big.
 
If there is enough interest I can write something up. Frankly I haven't  
seen it (with hams).
 
I am using fractal collinears here in form factors of inverted V's at  
moment. Mucho DX. I run EU on 40M most evenings.

Hey  Gang

OK - here is a question - anyone out there doing custom  beams?  I have 
kind of a sticky

Right now I'm running a Force 12  D-140, frankly because that all that will 
FIT - I have a 38ft piece of  property, and it has an 18 ft turning radius

I'd LOVE to have a bit  more gain, but even the smallest shorty 40s I've 
found are SLIGHTLY too  big.

I was wondering if anyone could design a 18.5 ft or less turning  radius 
40m beam...
