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.
