- thinking more about a bluetooth TeleDongle variant.  the basic idea is to 
  use a cc2540 soc to provide usb and/or bluetooth interfaces, and a cc1101 
  transceiver on one SPI port for our RF modes.  Thus the code runs on the 
  bluetooth part unlike all our other designs.

  swrr072 is a USB dongle design that shows use of a Johanson integrated balun
  that's 0.68 at q100 with a pcb trace antenna on 2.4ghz .. pcb is 4 layers
  and 1.616 x 0.632" .. looks like I could take the RF end of the design as is
  for the 2.4gzh end.  Maybe make the board wider to fit some hammond box?

  using a Hammond 1591XXMTBU or 1591XXLTBU, could put the 2.4ghz antenna on 
  one of the long sides, and UHF SMA and USB+power switch on opposite small 
  sides?  Can I find a suitable lipo to mount on the non-2.4ghz side?

- after much online discussion, the new plan is to use a cc1111 and a Rayson
  BTM-182 bluetooth module .. the latter should be budgeted at about $15 each
  in quantity 100 .. uses async serial, less dev effort, no regulatory issues
