...nothing.

Whatever is received by the antenna is what is received by the antenna. That goes into the electronics on the radio which do the magic.

This is supposed to be a built-in feature of some 802.11n chipsets.

So how does the connector distinguish between these antennas and relay information to chip set to "phase differently"? I am assuming these antennas are passive with no smarts.

Phase. Yes, it's built into the chipset. 450 does it too. At least the 3.65.

Wondering what the 3x price difference between antennas gains you.

Supposedly it makes up for the loss by using the desired signal component from both antennas. I remember reading the original white paper, and I remember thinking I understood it for about 5 minutes or so.

So you have a Dual slant AP and a V/H SM? Isn't that just losing signal
for no reason?

They've apparently got some electronic magic that can take the received signal on V/H and calculate what the transmitted dual slant signal was. It's been explained here, but I don't remember the details. They assert that you can mix and match safely. In fact they started out selling slant pol sector antennas and V+H SM's, so they are/were confident enough in this to make it the "default" setup.

It's a feature of their 802.11n chipset, so the computation is done in hardware.

I'm looking at the Cambium 2.4 antenna C024900D004A, and it lists it as being DualSlant +/-45 degrees. Does this mean that the Force 200 2.4 radios are also Dual Slant to talk to this antenna? I didn't find anything on the Force200 spec sheet talking about slant. If you use a V/H Antenna as the AP, can you not use the Force 200 as the SM?
