1. An apparatus, comprising:
- at least one power amplifier;
a plurality of antennas, the plurality of antennas including at least one antenna to receive wireless data signals and to not transmit wireless data signals, wherein the at least one antenna is capable of being connected with said at least one power amplifier; and
a switch to switch a connection with the at least one power amplifier, said switching between the at least one antenna and at least one other of the plurality of antennas, wherein said switching is to occur when the wireless station is sounding a complete channel matrix for a remote device;
wherein said plurality of antennas are three antennas and said at least one power amplifier are two power amplifiers; and
wherein a first of said two power amplifiers is non-switchably connected to a first antenna of said three antennas and a second of said two power amplifiers is switchably connected to a second and third of said three antennas.
