Currently we have 1231G routers with a single mast mount omni hooked to the primary antenna connector. If we upgraded to 1250 series, would that single antenna still be enough for 802.11n, or would we need 2-3?

You'll need three per radio module for full MIMO.  Take note that the 1250 has TWO radio modules so that totals three 2.4Ghz Antennaes and three 5.0 Ghz antennaes.


Here's a list of recently released antennaes for the 1250.  Look at the PDF files.

Would a single antenna still work (although not at full capacity?)


We currently have AIR-ANT2506 (2.4 Ghz Outdoor Omni) in use and it looks like the only outdoor omni for the 1250 series is in the 5Ghz range (AIR-ANT5160V-R).

Sure it'll work.  But don't expect to enable 802.11n because "n" requires both 2.4Ghz and 5.0Ghz to be active.
