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

[Bruce Richardson]

Hi Donn, 

Good point and a tiny bit of data I failed to include.  My notes here say
that on the beefy one that I think is the "wind profiler", the first
director (D1) in front of the DE is 33.5".

On the other antenna that I think is 222 (10-ele), the D1=24" and the
D8=19.25"

I don't expect that to be enough info. I will collect more data the next
time I'm in the barn.
Thanks for your thoughts.

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.
