What boom length is "compromised?"  All of the yagi studies 
show a regular increase in gain with increasing with boom 
length.  As long as there are enough elements to "fill" the 
boom and the elements can be properly "tuned" the Yagi will 
produce gain.  Feed impedance (bandwidth) and F/R are much 
more critical than gain ... here the tunability of the SteppIR 
design overcomes several issues.
