Quick question on this: Doesn't the Rev. F have the internal antenna soldered to one of the radio connections like the Rev. D and older have?
I just opened up an old Rev F.
There is only one antenna lead, connected to the external antenna. The wireless controller/chip is soldered to the top of the main circuit board. The antenna lead attaches to a "Chain 0" connector, also on the top of the main circuit board. There is also a place on the board for a "Chain 1" antenna connector, but there is no connector present.
So.... definitely no second antenna, and no second stream. Max speed is 65 mbps.
