When comparing between the 2 models of external antennas (AIR-ANT5170P-R and AIR-ANT2460P-R), I noticed that they comes with different number of connectors (RP-TNC). The AIR-ANT5170P-R comes with two connectors, while the AIR-ANT2460P-R comes with one connector.
Assuming I'm using the Cisco 1242 Series Dual Radio AP, how many of the AIR-ANT2460P-R antenna do I connect to the 2.4GHz ports?
I believe I will only need to connect 1 unit of the AIR-ANT5170P-R antenna to the 5GHz port, as it already comes with two connectors.
Well the AIR-ANT5170P-R is a Diversity patch antenna so you will use two connectors. The AIR-ANT2460P-R is not Diversity. For indoor use you do want to run diversity if possible. You should connect both of the connectors to the AIR-ANT5170P-R. For the 2.4ghz side you should of gotten AIR-ANT2465P-R so you can run diversity.
