[TowerTalk] 80 M 4 SQUARE MODELING

[cqtestk4xs at aol.com]

Now that I have finished my tower for 40-10 meters I need to start my next project.  I'm limited to the one 90 foot tower I have by county code.  I am planning on running 4 ropes from the last guy point (84ft) to install a wire 4 square for 80 meters.  Wires would be suspended vertically from the ropes in a typical 4 square pattern using Comtek switching.

Before I go through all the work installing the antennas and the radials (yuch) I want to be sure the tower and all the antennas on the tower will have minimal effect on the 4 square.  I'm using Philly for the guy wires so that is not an issue.  I can mess with the HFTA program all day long and feel comfortable working with it.  However, this is not a project for HFTA and my computer antenna modeling skills are sorely lacking.

Is there anyone out there who could model this setup to determine if the tower and antennas will negatively affect the 4 square system.  I would be glad to share the exact details of the antennas, their heights, length of boom etc. off reflector to facilitate the analysis. 

The 4 square is the only high performance system I can use out here due to the restrictions set by the county so any help on this would be appreciated.
