Description

The Naval Coastal Systems Station (CSS) in Panama City, FL is seeking sources for a Wideband Antenna System for Installation on the Naval Special Warfare (NSW) platforms. This activity is seeking market research information and sources capable of providing design, hardware and services for a VHF/UHF LOS/UHF SATCOM/GPS Antenna System for installation on maritime craft, including small boats and submersible vehicles. The following specification defines the physical and performance requirements for a Global Positioning System (GPS), VHF/UHF Line of Sight (LOS) and UHF DAMA and NON-DAMA Satellite Communications antenna system for installation on NSW maritime platforms. The antenna system will support LOS communications from 225 MHz to 400 MHz. (2.1.2) The antenna system will support 5 KHz and 25 KHz UHF DAMA SATCOM for dual mode high and low angle operations from 243-270 MHz (Receive) and 292-318 MHz (Transmit). UHF antenna gain will be greater than 0 dBic at boresight (>+3dBic desired) at all angles (> 5 degrees elevation angle) when positioned 1meter above the ground plane. The antenna system shall be capable of receiving military GPS signals at 1227 MHz and 1575 MHz simultaneous with VHF/UHF LOS or UHF SATCOM operation. It shall be rated to handle 100-Watts (min.) continuous (CW) power. It shall be SINCGARS and Have Quick capable and shall be omni-directional in azimuth in both transmit and receive modes. The antenna will be ruggedized and certified capable of being transported underwater in both fresh and saltwater to a maximum depth of 120 FSW. It must be constructed of materials suitable for use in the submarine environment. The external surface of the antenna will be designed to disperse rain and other moisture so that their effect upon RF performance is minimized. It shall be capable of being mounted to an existing antenna position by means of a CSS-supplied adapter. (2.2.5) The system shall be no larger than 20 inches in height and 8 inches in diameter. The antenna will weigh no more than 10 pounds in air and shall be neutral, to slightly negatively buoyant in seawater. The antenna system will incorporate a low Radar Cross Section (RCS) outline. Operating voltage (if any) available for the antenna system will be +28.0VDC + 2.0VDC. (2.2.8) Factors of Safety. Structure, greater than 2.0; Fasteners, greater than 5.0. The antenna system will support dual mode high and low elevation angle UHF SATCOM in DAMA and NON-DAMA. It shall support VHF and UHF LOS in simplex and half-duplex modes. High and Low elevation angles will be Operator selectable. The antenna system will receive Military GPS signals while simultaneously conducting normal LOS or SATCOM operations. No steering or change in vehicle pitch/roll will be necessary for the antenna system to perform its functions. The antenna system must be compatible with the AN/PRC-117F and AN/PSC-5C/D radio sets. RF cables and control connectors will be waterproofed to withstand ambient pressures of 300psi. Antenna system RF connectors will be compatible with NAVSEA standard part number 53711-7005536-1. The manufacturer should provide data that demonstrates the proposed system's conformity to both the functional performance and the physical specifications contained in this RFI. The manufacturer should supply test data that demonstrates the performance of the antenna system proposed. This test data should include but not be limited to: VSWR, antenna elevation and azimuth gain patterns measured across the bandwidth (using both RHCP and Linearly Polarized source antennas), system power requirements, environmental test data, and off gassing. Antenna measurements should be made 1 meter above the ground plane. Any antenna system ultimately selected will be hydro-statically tested to 100 psi for 10 cycles in accordance with NAVSEA SYSTEM CERTIFICATION PROCEDURES AND CRITERIA MANUAL FOR DEEP SUBMERGANCE SYSTEMS (P-9290 rev A). This is a sources sought announcement only and is not a solicitation or Broad Agency Announcement. A solicitation will not be issued as a result of this announcement. If a solicitation is developed it will be advertised in the Commerce Business Daily, Responses requested by 30 April 2001. Reply to Michael A Doctor, Code R41,Coastal Systems Station, 6703 W.
