Hi all,
I am planning to erect a 20 meters high tower. I'd like to put the
following antennas on top of it:
- Cushcraft A3WS 3 Element - for 12 & 17 Meters
- Cushcraft XM240 2 ele - for 40 Meters
- 80 meters inverted V
Alternatively, I may use:
- Cushcraft XM240
- Cushcraft X7
- a 5 element yagi for 6 meters
- 80 meters inverted V
I've already built/installed the 3 (very heavy) guy anchors on the ground,
each at 16 meters from the base of the tower. As we don't have any
Philystran distributor here, I am going to use EHS guy wire. So interaction
may be an issue.
Considering that wind is not a real concern in our area, my questions are:
1 - how many EHS guy sections are recommended for this tower and at what
heights?
2 - where can I find somebody to make the modeling of this system, so I can
find the correct lenghts to break the guy wires in order to avoid interaction?
