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...

Are you sure these cover 2.4 GHz. There are multiple
versions of the
CELLMAX-EXT and e.g. the CELLMAX-EXT-CPU seems to not cover 2.4 GHz while
the CELLMAX-EXT-CPUSE does cover 2.4 GHz:

if we're sure they cover 2.4 GHz then we'd love to get them! I'd pay up to
$100 in that case

Fitz says they can probably be won for $25 and i think he's willing to
bid on them for sudomesh
so if sudomesh wants them, they should tell Fitz how much Sudomesh will
pay for the lot. 140 pounds of antennas.
Fitz, did you have a datasheet on these antennas? I believe i recall
they were wideband in the 900MHz and 2.4GHz bands?
