Understanding External Antenna Deployments

All Cisco antenna connectors are labeled; "A," "B," "C," and so on. "A" has a higher priority than "B"
or "C/D" so, if the AP supports say 3 or 4 antennas and you only have 2 antennas, you can use them on
ports "A" and "B" for a short term until you install the additional antennas.
