The MonstIR is 3 full-sized elements on 40M on a 34' boom.  34' is WAY too 
long for a two element 40M beam.  M2 uses a 19'7" boom for their 2 element 
beam and 29'7" for their three element beam.  Force 12 uses 18 to 24' booms 
for their 2 element beams and 35'7" for their three element beam.  You could 
certainly build a 3 element wide-spaced beam on a 42-48' boom if you wanted 
another 2/3 db gain, but the MonstIR boom length is on par with the other 
commercial 3 element yagis.  And it is full-sized.
