A Salt Lake firm has won a $10 million contract from the Federal Aviation Administration to provide antenna systems for the nation's air-traffic control program.

The contract is expected to add 12 new employees to the company's current 60-member staff.JTP Radiation will provide 119 TACAN antenna systems under the contract which gives the FAA an option to order 84 more at the contract price.

The TACAN antenna systems are used to provide range and azimuth bearing to aircraft operating within the United States and its territories and possessions. The FAA has more than 700 systems currently in use, most constructed in the late 1960s and early 1970s.

The JTP antennas will be used in the first phase of a replacement effort authorized by the FAA National Airspace Plan.

The JTP 900 TACAN Antenna System is the result of several years of research and development and features major breakthroughs in antenna, motor and composite material technologies. JTP was formed in 1978 by Joseph Jarvis, Dean Thornberg and Sid Pickles to conduct internally funded research and development into a new generation of specialized antennas.

JTP won an FAA contract in 1984 for distance measuring equipment antennas and contracts.

JTP, a division of Airspace Management Group, moved into a new 45,000-square-foot facility near the Salt Lake International Airport this past June.
