Are you sure about the modules having a built-in antenna?
All the devices I've found that use them have an external antenna.

P.S. So the RF12 fans don't feel envious of all the IM-ME hacking


It's called an ETEK's RF12, but looks like it's based on the same
Integration/Silicon Labs IP as HopeRF's RFM12

The datasheet is an appendex to the 'Technical Description'
