Main problem is that to get a 120 degree pattern with 16 db of gain you have to have a razor-thin vertical arpeture (around 6 degrees). So you're probably going to have to use the two-man method you're describing to get optimum results, or use a lower-gain antenna. Tom S. - Original

We have a lot of those sectors out and some of the lessons we learned were: 1) The higher the DB the less downward/upward range it covers, 2) same for 90's versus 120's, the 120's have a lot wider downward coverage than the 90's. Its hard on us because all of our towers are are on steep hills
