The National Telecommunications and Information Administration (NTIA) requires 12 folding antennas with the following specifications. Antennas shall operate over a frequency range of 0.1 -- 1.0 GHz minimum. Antennas shall have a nominal impedance of 50 ohms. Antennas shall have a minimum power gain of 4.8 dBi. Antennas shall be unipolarized. Antennas shall have operating temperature ranges at a minimum of -30 degrees C to at least a maximum of 60 degrees C while maintaining calibration and data integrity. Antennas shall operate in rain or snow without degradation of the electrical specifications. Antennas shall be individually calibrated over .1 -- 1 GHz in the far field to produce electric antenna factors. Antennas shall be mountable on a flat horizontal plate or mountable on a vertical pipe. The antenna mount shall swivel over a 90 degree range to orient the antenna for both vertical and horizontal polarizations. Antennas shall not exceed 54 inches x 8 inches when completely collapsed for storage. Antennas shall be made of durable and light weight material and have a maximum weight of 25 lbs. The radio frequency connector shall be a type N female. Antennas shall have a minimum wind load of 120 mph. The elements shall fold along the boom for storage and shall be able to be hinged-locked in place. Removing antenna elements shall not be required for storage. The elements shall remain attached to the boom at all times. The antenna's mounting point shall be within 6 inches of the antenna's center of gravity. The antennas shall have a carrying case. It is not the intent of the Government to issue a separate solicitation for this requirement. Interested sources proposing to supply equivalent items must submit a written qualification statement by fax, clearly establishing capability to meet the above requirements within 15 days from the date of this synopsis. Any qualified bids will be evaluated on technical merit, past performance and cost. In the absence of other qualified sources, it is the intent of the Government to negotiate a sole source contract under the authority of 41 U.S.C. 253 (c)(1) with Tracor Aerospace Electronic Systems, Inc., 305 Richardson Road, Lansdale, PA 19446-1429.
