[NLRS] Those wind profiler 222 beams that were available backwhen...

[WA2VOI, Donn]

Hi Bruce.

Measurements would help: first three elements (reflector, driven el & 1st director) and 
spacing of same.

I don't know of a "wind profiler" in the 220 region but it  possible.  There is (was ?) 
one in SW MN at 449 MHz (in the Mil band).  Allocation table says "Government - Fixed and 
Mobil" between 225 and 328 MHz and "Non-government" with no classifier.  A note says "FAA 
provides air traffic control communications to the military services on selected 
frequencies in this band."  I suppose that could mean wind shear data.  Also, isn't 243 
MHz a military airborne Emergency channel ?

They look like nice antennas, especially the 10 el.
