...we have lots of rock right below the surface. You plant small trees
with a pick and shovel. Most of the backyard was built by bringing
dirt in.
toroid windings.......
c---- A

c winding #1
c
c---- B
c---- C
c
c winding #2

c---- D
c---- E
c
c winding #3

c---- F
Connect B to C, D to E ... 50-ohm coax to F, shield/ground to D/E ..
450-ohm balanced line to A and F.
Voila!
....I don't think that is balanced because one side is two windings
from ground and the other is one winding away. The turns ratio is
right (3x) for 9:1.
