I haven't looked at the antenna design details or tuning. I have been working on two general purpose MSP430 boards that interface with various peripherals and came across the Chipcon CC2500. I added the reference design (folded dipole) to one of the sensor peripherals that connects to the uC board. I have not gone out for boards yet.
