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?
