[TowerTalk] Multiple Tower Layout Application

[Byron Tatum]

 Hello-   Does anyone know of computer applications to assist in the layout of multiple guyed towers?   I am wanting to lay out 3 of 45G guyed towers (per Rohn 130 MPH spec) in the most logical format based on these criteria:1. A 100' tower for HF antennas.2. A pair of 120' towers for VHF, UHF and SHF.3. A building housing the hamshack will be located close to center, between the pair of 120' towers, in order to reduce feedline (1-5/8") lengths and attempt to equalize lengths to each tower.4. The 100' tower can be somewhat further away as feedline (1/2", 7/8") losses will not be as serious.5. The property available for towers is close to square being 380' per side. I am attempting to try and keep as much as possible toward the west property side. This square is close to having edges running N-S and E-W.
I have drawn out several plans on graph paper whereby there are no "interweaving" guy wires. I was hoping to be able to capitalize on having clear stretches between towers to run dipoles or loops but it is very difficult to try and use the minimum of space and accomplish such. I am faced with this task at a new QTH that I am starting work at and wanted to try and get the best possible layout. I plan to put up a metal shop building/hamshack in an appropriate place between towers. I have been planning for this and have enough guy wire insulators/hardware to break up guy wires every 27' to try and minimize HF interaction.  I would consider "interweaving" the guy wires to be able to get towers a little closer and minimize feedline runs.Thanks,   Byron W5FH
