Can one of you guys who has access to the NEC wires program help me
with a radial question?
Does a "radial" need to be in the radial direction in order to
collect current, or does it still collect on any portion which may be
in the tangential direction?
The reason that I ask is that my tower is very close to the house,
and, although I have some radials on the roof, they are only 10-15m
long. On the other side of the house is the driveway and then the
boundary. I could have one or two radials running along the drive on
either side, but don't want to grind any more slots in it than I have
to.
Suggest the following simulation. Set up a vertical with say 4 X 15m
radials and calculate the current in them. Then add a 20m Tee
section on to the end of each and recalculate.
Would appreciate someone running this for me.
Thanks.
Greg, ZS5K.
