Can someone please let me know which externally mounted antenna is the correct part to use with a AIR-AP1252 N-Series, (6dBm gain or more, its to cover a playing field)
I've been scouring the Cisco web site for days to find a definative answer and am getting confused.
Ideally it needs to cover both radio bands but if it only does 2.4Ghz, I'll settle for that as my life is ticking away.
Any idea on the wall mounts too.
All help appreciated
Keep in mind that you can use any 2.4GHz antenna on the 1252. Some antennas have three cables for convenience, but in reality there are three individual antennas inside the casing. You can attain the same effect by purchasing three of the same kind of antenna and connecting them to the 1252.
The AIR-ANT2506 is a good outdoor antenna and would be fine for use with clients as long as it's installed close to the ground. Omnidirectional antennas are quite deceptive in how they work - they actually form a donut-type coverage that gets "squashed" as gain is increased. A 5.2dBm isn't too bad, but if you install it too high then the signal will go right over the heads of the users. I guess I mention all that to say that you shouldn't install it on a 20-foot pole on top of a roof. :)
To take full advantage of 802.11n, you'll need three antennas. Otherwise, one or two would suffice fine if you're in an 802.11g environment.
