Hello,
I want to implement a MIMO system using USRP2, I just have USRP2s and
MIMO cable.
Do I have to use an external clock source ?
I searched the maillist and found: Each USRP2 can handle 1 antenna
with most daughterboards, or 2 if you
have your own external RF sections connected to the USRP2 at IF.
Does it mean I should buy “external RF sections” to use 2 antennas on 1
USRP2? Or where can I get them?
If I want to build a 2X2 MIMO system,-- 2 USRP2s, 1 MIMO cable, the
“external RF sections” said above, – Is that enough?

No. With the mimo cable, you can share a clock reference between a pair
of devices

You should select a daughterboard based on the desired frequency
coverage. Typically transceiver boards have 1 tx frontend and 1 rx
frontend. The TVRX2, which is RX only, has 2 rx frontends.
