I would not do this plan ....
1. 1.5 kw split equally (good question itself) FOUR ways is 375 watts for
each antenna. Someone with more data can compute the ERP and directions.
2. Most useful, simple, is to point fourth ant to SA, and swing the stack
only from 330 for JA to 35 for EU, only 95 degrees...AND switch to the SA
instead of joining it to the three others.
3. Prior to Force 12 entries, there was a very good plan for three TH-7...
one at 40, second at 75 and third at 100 or 120 or something like that on
one rotating tower.
4. This plan locks your station into a single operator with limited
I did not mention other of the many variables. GL, 73 Charly
