I'd like to hang a trapped 160/80 inverted vee off my 110' tower as a
temporary solution for the low bands this year. The tower is on a steep hill
and too far from trees for a dipole to be feasible, so it'll have to be an
inverted vee. I have a 40-2CD at the top of the tower, and a 3-stack of 4-el
SteppIRs on Tic rings at 96'/64'/34'. The 14' spacing between the 40-2CD and
top SteppIR make it impossible to hang the vee above the top SteppIR and get
enough clearance for the yagi to turn. I'd like to hang the vee right under
the top SteppIR, say at 94 feet, to get it as high as possible, but I'm
concerned about interaction between the vee and yagi. After all, I went
through a lot of trouble and cost to put Phillystran guys on this tower to
avoid interaction!


Is it likely the vee will interact with the yagi? Would it be better to hang
the vee at 85 feet and put some separation between it and the top SteppIR?


Also, does it matter how far from the tower I hang the vee?
