Roy and Mr. Sugalski,
	I agree that you should get the information from the application they will
have filed with local authorities.  Nevertheless, I want you to know that I
think these antennas are communications links between cell base stations.  My
expectation is that these links replace the land lines that the telecom.
companies could use to communicate between individual cell base stations - not
between cell phones and base stations.  I don't know the frequency of these
communication links, but the size of the dish indicates either the high
frequency end of the RF band or the low frequency end of the microwave band. 
The wavelength of an electromagnetic wave of 100 Mhz frequency would be 3
meters.  If you assume that the radius of the antenna dish should be
comparable with 1/4 wavelenth, you would have 0.75 meter for the dish radius -
about 2.4 feet.  Thus, I suspect that the antenna is for a link operating at
about 100 Mhz frequency.  Technically speakling, this is RF instead of
microwave.  You also have the advantage that the absorption of this radiation
in human tissues (like gray matter) is about 1/2 the absorption of radiation
with 1 Ghz frequency.  Still, I think you should find out what  the frequency
and power of these sources are by obtaini ng a copy of the application.
