Hi!
Without knowing technology and configuration: Yes, it works.
I've seen two cases in use in GSM:
- BCCH+TCH on one antenna, second antenna only for diversity.
Second antena tilted a bit to minimize uplink interference.
make sure BCCH+TCH is not moved to second ant during some upgrade/maintenance.
Second case, in fact two sectors in hilly area, both with same direction (very simmilar),
one uptilt, one downtilt.
One more case I've seen in the mountains: antenna mounted horizontally.
So, it has 65 degrees vertical lobe (to cover mountain acrooss the valley), and 8 degrees horizontal lobe.
