I did reboot. Hence the wondering whether the fix was really changing
freqs or rebooting.

Changing anything to do with RF, and many other parts, requires a
reboot
on the eNBs. If you didn't reboot, request reset reset, after
switching
to split2x2, you were prabably not actually operating in split2x2 mode.

The other thing is I had to reboot to change the frequency. I didn't
try just rebooting before hand. I don't want to think that a reboot
was
needed. A mysterious problem that goes away on a reboot is scarier
to
me than a mysterious but deterministic antenna configuration problem.
I guess I'll have to do some experimenting.
