the lunar orbit is ~ 5.5 degrees to the ecliptic, which is 23.5 degrees
to the equator, so the extreme lunar declination would be about 29 degrees.
so if the beamwidth of the "fence" is wide enough, it may be possible for
the Moon to brush up against it.

but it does seem hard to believe;  can someone comment on how long a
typical LEO object spends inside the "fence"?

is that the ERP or the actual power fed into the array?

the obvious guess is that the dipoles are end-to-end, as in:

	---   ---   ---   ---   ---   ---   ---   ---   ---

but it would be interesting to see this picture.
