Dear Team
We are using 3 1532e AP’s on 3 buildings to make it a point to multipoint connection. I will be using an external directional antenna (AIR-ANT2588P3M-N=) on each 1532.
My question is, will I need extra coaxial cable to connect between the antenna and the AP or I can fix the external antenna directly on the AP.
I think the (AIR-ANT2588P3M-N=) has 3 antenna ports and the 1532e has 2 dual band ports, each for 2.4ghz and 5ghz. The antenna installation guide only talks about the 1552 and not the 1532 AP.
My questions are.

The antenna is to be used with the Cisco access point. The port-to-port designations are as follows: port A of the antenna must be connected to port 4 of the access point, port B of the antenna must be connected to port 6 of the access point, and port C of the antenna must be connected to port 5 of the access point.
Note Coaxial cable loses efficiency as the frequency increases, resulting in signal loss. The cable should be kept as short as possible, because cable length also determines the amount of signal loss (the longer the run, the greater the loss).
Cisco offers low-loss 5 ft. and 10 ft. coaxial cables, parts AIR-CAB005LL-N and AIR-CAB010LL-N, respectively, for connection from the antenna to the access point. These cables have one straight male type-N connector and one right angle male type-N connector. To use all of the ports on the AIR-ANT2588P3M-N three cables will be needed.
After the cable is attached to the antenna, make sure that the connections are sealed (if outdoors) to prevent moisture and other weathering elements from affecting performance. Cisco recommends using a coax seal (such as CoaxSeal) for outdoor connections. Silicone sealant or electrical tape are not recommended for sealing outdoor connections.

Hi, The 1532E only has 4 ports, 1-2-3-4, no 5 and 6. Did you mean port A to port 1, port B to port 3 and port C to port 4? I just received 3 sets and cannot find any documentation as to which antenna ports connect to which radio ports using the 3 port AIR-ANT2588P3M-N.
THANKS.

There are two terms that are used when referring to Antenna Band Mode Configurations:
Please note that Antenna Band Mode is only available on the 1532E model, with external antennas.
When installing the AIR-ANT2588P3M-N with the Cisco Aironet 1530 Series AP, connect the outermost antenna ports (marked ‘1’ in Figure 2-18) to the AP’s dual band antenna ports.

Thank you, so I take it the middle connection on the antenna would be used for single band? I can't see any other reason for the third port. Thanks, Dave
