9800 Access Point Antenna Configuration

[jeustace]

On the older WLCs (pre-9800), if you had an AP with multiple external antenna connections you could choose to disable some to match a particular antenna setup.  e.g. in a lift previously I have installed an AIR-AP3802E-E-K9 AP on the lift car, disabled antennae B, C, and D and run a co-ax from antenna A to a small dipole inside the lift car to get enough coverage in it which worked fine.

Is that same configuration possible with a 9800 controller and C9115AXE-E APs?

Have you reviewed the install and setup guides @jeustace ?

That's useful info thanks. Looks like I may have to connect a minimum of two.

[Rich R]

Agreed it looks like you need to use at least 2.

why you need to disable antenna ports?

[jeustace]

I'm only connecting one antenna. In my experience, single stream transmissions are sent through the four radios on a round robin basis so you have to disable any RP-TNCs which don't have an antenna connected.
