Hi all
First of all, many thanks for the extremely helpful advice you have all
offered, both on and off list.
After giving this some thought, I am going down the route of detuning the
towers, and modelling the potential solution. At this point, the actual
towers havn't been installed, although I have permission to install them.
They MUST be in a square formation, but can be between 20 and 50 m apart.
Each tower will support various Yagi's....So.....
I am using MMANA to model a 4 Square on Topband, and need some help.
Although I have a working 4 Square file that MMANA can use, I am puzzled how
to model the effects of the metal supporting towers in MMANA.
Background:
Now then, I plan on running a catenary wire (well rope) from the top of each
tower to the next one. This will support a T aerial, fed against earth (or
elevated radials). The vertical part of the T will be 80 feet, the remaining
top part of the T will be about 40 Feet a side. This seems to work FB in
Freespace in MMANA.
What I need to do is to model the effects of the supporting towers. I am
particularly interested in the effects on the radiation pattern / angle.
The plan is to detune the towers with Gamma Rods with either Capacity or
Inductive loading.
Question is, how far do I detune them, given that an 80 M 4 Square is
planned as well.
Thanks
Any help ?
Thanks
