YO7. I am stacking 2 4L SteppIR antennas which allows me to change element 
lengths but the element spacing is fixed. In attempting to optimize I get 
different spacing. I would prefer not to change spacing and now that they 
are up probably won't for sometime. Any ideas?

         Simple!  Go into the Elements menu, and enter an
X for each element you want fixed.  I didn't want to mess
with my KLM log-cell for several mechanical reasons, so I
simply fixed those two element positions and optimized what
remained...I'm sure glad you didn't ask me now to model the
tapes in a SteppIR!
