These antennas are electronically steered, and will do multiple microwave frequencies as well, (2.4 ghz and 5.8 come to mind) the method I wont belabor, but its quite do-able.
You take a van, a bread truck cube van for example, install steerable panels on all four sides, Aegis style, and youve got a mobile Sigint vehicle. You log readings, direction of best signal, your GPS coordinates and drive around.
This gives wardriving a new meaning.
I'll be the first to admit its a big project, and the antenna design shouldnt be too complicated, seeing you only need the two frequency bands.
