The Wind Profiler System is a Doppler radar which measures wind speed and direction in a vertical profile. A Wind Profiler Demonstration Network, consisting of 30 profilers installed in the central United States, California, and Alaska, is now in operation. The National Data Buoy Center indends to solicit proposals for five (5) coaxial-collinear antennae to be used with wind profiler systems.

The frequency of operation is 449.0 MHz; power level 1.5 kilowatts minimum average power and 9.0 kilowatts minimum peak power; beams electronically switched with beam-pointing positions at zenith and 4 orthogonal positions at 15 +/- 3.0 degrees off zenith. Copies of the solicitation will be provided only in response to written or faxed requests (fax 601 688 3153). Telephone requests will not be honored. (0083)
