So i ordered some rp-sma bulkhead connectors, and I see 6 antenna connections inside this router. I was wondering if you guys knew which ones did what. The only one i need to use are the 2.4ghz G and N, I don't need the 5ghz antenna. On the picture below does anyone know which ones are for the 2.4ghz chips?

You can flip of the cover of the amplifiers, the two SiGe 2528L 2.4 GHz power amps are for 2.4 GHz.
I guess anyway that the longer, folded antenna's with gray wire are 2.4 GHz and the shorter ones with black wire for 5 GHz.

sorry i didn't really understand your post, which ones are the 2.4ghz antennas? theres 3 black on the left and 3 gray on the right, the black wire lengths are actually longer than the grey ones, they go under and one goes to the center and the other goes all the way to the other side

3 antennas with gray wire are 2.4 GHz.
3 antennas with black wire are 5 GHz.

What about v2 of this router? On mine, the circuit board has labels, and I'd love to know what they mean. I assume the 2's are 2.4GHz, and the 5's are 5GHz but I'm just guessing.

2A - antenna 3 - black wire
2B - antenna 1 - grey wire
2C - antenna 6, black/grey wire
5? - antenna 2 - black/grey wire
5? - antenna 4 - black wire
5? - antenna 5 - grey wire

I already started fiddling with the three 5's and I forgot which wire went to which Sad

I'm building a custom road case, and I only have room for 2 external antennas. I don't care about 2.4GHz, but how should I determine which two of the three 5GHz connections are most important?
You can see the two external connectors I already added, I'm just trying to figure out where to plug them in.

The 3 antennas with wires connected to the upper left chip is 2.4GHz. The upper right area is the 5GHz chip.

Thanks, that's good to confirm what I suspected. But what is the difference between A, B, and C? If I only use 2 antennas with this, where should I plug them in? I did some non-scientific testing watching the RSSI on a connected computer while I changed the antennas, and it didn't seem to matter much.
