	Any chance of a really clear telephoto picture of the actual top
of the mast and yagis ?  The existing photo is too compressed and blurry
to get a clear idea of the yagi details, particularly a guess as to the
frequency involved.   And the vertical antenna with the sleeves above
the yagis is also an interesting clue as the sleeve length and spacing
is likely precisely related to the frequency it is cut for.   It would
of course be omni directional vertically polarized with significant gain
toward the horizon.

	It looks superficilally like VHF highband to me, but obviously
anything that would allow a more precise guess would help narrow down
what this is.

	If it is some kind of TV station signal calibration, likely the
yagis are VHF HI tv, but why such an activity would involve two trucks
over an extended period of time seems completely mysterious as TV signal
measurements can mostly be made once at a particular location in a few
minutes and don't take days.

	I suppose such a rig could be used to listen for an FM band
pirate, but it seems unclear why that would take days either.

	The use of such a tall antenna would suggest the signal of
interest is possibly some distance away...
