It is surprising how much other vertical objects can affect the pattern of
phased verticals. You can get the best answer by modeling your purposed
systems to see what interaction is acceptable to you. I would imagine that
you will need hundreds of feet separation.

Hi everyone,
Iam planning on building a "small contest" station on 20 acres. I plan on
having a 4square array on 80m, and 2 ele yagi @70' for 40m, and eventually a
1/4 wave vertical for 160m. Rigs will be FT-2000 and FTdx-3000. Question is,
how far should the 80m four square and 70' tower (with 40m yagi), and 160m
Towers be separated to not interfere with each other at about the 1000 watt
range?
Thanks and 73
