Dang, well I picked up the pallet of antennas and it looks like they're the CELLMAX-EXT-CPU which only cover 806–960 MHz and 1710–2200 MHz :( . Hey but on the plus side, they contain tee couplers that are rated for the full 698–960 MHz and 1710–2700 MHz. I've needed a 2.4Ghz coupler for a while now and that alone was worth the minimum bid for me. With one of those, a noise source and a spectrum analyzer, I can start characterizing Wifi/Bluetooth antennas.
The antenna design is relatively simple and pretty cool looking. It would be interesting to try and simulate the design and see how much would have to change in order to extend the range. Also, if anyone wants to build a phase arrayed radar system...
