[TowerTalk] Modelling Stacks

[Howard Klein]

The current discussion has brought to mind a problem that I have had with 
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?

P.S.
Actually in practice they work well but would like to squeeze out the last 
drops. I think you know what I mean.
