Functionally this is not split mode, it's an omnidirectional array.
Do omni's cause issues? We have a bunch of omni sites, so if we're
already hurting ourselves that would be good to know....I mean hurting
ourselves in ways other than the obvious problems intrinsic to omnis.

Well the main issue is that in order to do the current split there was
a lot of coding to make sure that the RF didn’t cause any issues. The
setup you describe would likely break any of the internal algorithms
and run pretty horribly.

Subject: [Telrad] splitters
We know we can put two sector antennas back to back. What if we had 4
90 degree sectors in an array and used a set of hybrid
splitter/combiners to connect all 4 antennas to one compact?
Omni coverage without farting around with omnis. To expand capacity
you remove splitters and put in a second BTS.
You would lose 3db from splitting, and probably another db to insertion
loss and extra cable, but you can make that up on the Tx side by
turning up the Tx power. You'd be a little weaker on the Rx at the BTS
and you couldn't fix that, but download is more important than upload
so maybe I don't have to care.
Is this a bad idea for any other reasons?
