[NLRS] Looking for advice about tower interaction with 902, 1296 and 2304 antennas

Hi Tod, sounds like a great set-up !    Here are my $0.02 worth.    First,
if my trig is right (??), a 26" section at 40' subtends a 3.1 degree arc
..... that is, if that tower causes a blockage, its would be over a bearing
of 3.1 degrees.     Second, my thinking is that since the tower is not
solid, its lattice, that it may not form much of a block.     Even at the
lowest frequency of 902, that second tower is over 40 wavelengths away, so
its in the far field.   I think its a good idea to engineer its position so
that it would have minimum impact (in terms of activity in that direction),
but my feeling is that is should have very little, perhaps no noticeable,
blockage.    I'm interested what others have to say.
