That is a TV Electronic News Gathering (ENG) antenna.  Most likely a NSI or 
Nurad Super Quad model.  They have been around for a long time and there are

lots of them around.  Inside the radome is a fiberglass cosecant squared 
antenna that is about 4 feet tall with a CP antenna feed mounted out the 
front.  It for sure is for receiving 1990 to 2110 MHz and may also be 
equipped for 2.5 GHz, 6.7 to 7.3 GHz or even 12.7 to 13.2 GHz.  There were 
receiving converters available for the higher bands over the years.  Now 
they are using Analog FM but in the next 2 years Nextel will be paying to 
convert everything to COFDM Digital.  The analog systems are pretty site 
friendly, the digital is something different but being this is a receive 
site you should be OK.  The analog transmitters generally run 10 to 15 watts

into a 24 Db gain antenna which is a decent ERP, the Digital transmitters 
are more like 2 to 7 watts into the same gain.

Like Bob Dylan said "times they are a changing".
