Ok, so I've gotten myself a little confused here and would like some recommendations. We are ordering new COWs (Computer On Wheels) for the hospital and they will be using an Intel 6205 Wireless Chip which is a/b/g/n 2x2. The two new floors these devices will be going on will be our first internal hospital entry into 802.11n which I force the clients to run in the 5ghz range for N. Previous to this, all of my cows are G clients and use a 2.2dbi rubber duck for 2.4ghz. I will be using 1142 AP's, if not 3502 and no I have not performed a survey yet as the floor is still in early construction, but equipment is required to be ordered now. I can tell you that I will be surveying for a voice grade. I suppose my confusion comes from what is the best antenna (obvious open ended question) for this card, being it has two connectors for the 2x2. Again, typically I would use a 2.2 dbi rubber duck for either 2 GHz or dual band 2/5 GHz. Is dual rubber ducks at 6inch spacing (half wavelength met on 2.4 GHz fall back) suffecient or are there other factors involved with the N.
BTW, what is the real term for the Rubber Duckie antenna?
I used these term from my experience with UHF/VHF radios. So "rubber ducks" are the standard omni-directional, articulated (bendable) or not, AIR-AT2422DB/AIR-ANT4941. I don't know what the old model is called but they're the same.
Rubber duckies are examples like AIR-ANT2422DG.
Rubber ducklings (aka thumb antennas) are AIR-ANT2422SDW.
So the real term of the rubber duckie? Rubber duckie.
So you think jus two dual band rubber ducks would work for n?
I don't know. You'll have to tell us what they are because we don't know either.
For dual-band antennas, refer to the last page of the link Antenna Product Portfolio for Cisco Aironet 802.11n Access Points, under the heading Dual-Band Antennas or Table 5.
Usually they just call then dipole antennas.

Thanks Scott. Sorry, Raun, I interpreted the e-mail as for the access points.
Coming from a Helathcare background and having ran into similar issues I can tell you this will be no easy task. We modified Lionville carts because of a similar issue. I also worked for a company that resold Jaco carts and we worked with them on where to mount the antennas. In fact you will see they have their (thumb) antennas on the work top (right corner) or mounted in back of the monitor arm. This was prior to 802.11n and in both cases with went with 1 antenna approach (non diversity).
I have not modified any carts since 802.11n and your question is a great one. Here is whats rambling around in my brain at the moment.
1 - Do the cows really need 802.11n speed. In almost all situations on the healthcare floor the answers is usually no. If this is the case consider turning of 802.11n speeds off on the cows and go with normal protocol. This could mean no diversityingle antenna approach. But what lead would be the single antenna coming out of the card we would have to find that out. If that can even be done with that card ... Never played with it
2 - I am assuming there are 4 antenna leads coming out of the card (2x2) ? Do you know or have a pic of it ? Now Im curious. Without knowing what end connectors we are limited on our antenna options. Ideally, we would want something off the shelf meeting your parttern requirements.
