52 -- S-BAND RACON COVERSION KITS SOL DTCG23-97-R-EC7056 POC Contact: LT Tom Snider, (202)267-2512, Contract Specialist; Ms. Linda H. Ovenden, (202) 267-2527, Contracting Officer The Coast Guard has a requirement to purchase 10 S-Band Racon Conversion Kits containing all parts necessary to convert the Coast Guard's CFAF Racons from single X-band to dual X plus S-Band Racons. All electronic components shall form, fit and function in the Coast Guard Standard CFAF Racon. The conversion kit shall contain all components necessary to meet standards set by the International Association Lighthouse Authority (IALA) and the International Maritime Organization (IMO). The Racon was designed to respond to the Coast Guard AN/SPS-64 (V) Radars and respond to interrogating radars at X-band (9300 to 9500 MHz, 3cm) and S-band (2900 to 3100 MHz, 10 cm) under the following conditions: The pulsewidth must be greater than 50 nanoseconds, and the pulse amplitude must be either greater than the receiver sensitivity threshold, adjustable from -10 dBM to -40 dBm for X-band and -10 dBM to -33 dBm for S-band, or greater than the peak amplitude value stored in SLS (sidelobe suppression) memory for a given radar. The racon can provide line-of-sight transmission well in excess of 15 nautical miles. The S-band characteristics below are limits designed into the Racon. The salient characteristics of the kits include the following: (1) S-BAND ANTENNA (12.5 Inches 4dbi): Horizontally polarized slotted array beamwidth Vertical Divergence 22 degrees, Horizontal Divergence @ 3dB Omnidirectional, Effective Radiated Power 3.0 watts. (2) S-BAND TRANSMITTER: A. Frequencies -- 2905 to 3095 +/- 5 MHz B. Peak power -- 3 W C. Pulse width -- 1.75 usec, D. PRF -- 1kHz +/- 50 Hz. (3) RECEIVER (S-BAND): A. Frequencies -- 2905 to 3099 MHz +/- 1 MHz, the PRF to 1 KHz +/- 50 Hz, the amplitude to -- 40 dBm +/- 2 dBm and the pulse width to 50 nanosec at the antenna connector. (4) RACON HOUSING: A. Cone Shaped Molded made of Lexan material 31 Inches. B. Minimum Reflection maintaining Vertical Divergence 22 degrees, Horizontal Divergence @ 3dB Omnidirectional, Effective Radiated Power 3.0 watts. The period of performance is estimated to be 120 days from the date of contract award. All interested parties must submit a Capabilities Statement that sufficiently describes their qualifications, capabilities, and previous experience relevant to fulfilling the above requirement within 15 days of publication of this notice. This notice is not a solicitation. A formal Request for Proposal is not available. In the absence of responses from firms which believe they have the capability to perform this requirement, the Coast Guard intends to negotiate with Tideland Signal Corporation, Houston, Texas, for the work described pursuant to FAR 6.302-1(b)(2). We believe that Tideland Signal Corporation holds the proprietary rights to the design of this item. No other notice will be published until award is made. All correspondence should be addressed to: Commandant (G-ACS-1B/TS), U.S. Coast Guard Headquarters, 2100 Second Street, SW, Washington, DC 20593-0001.
