BOULDER - First RF Corp. has received a contract for up to $24.9 million over a six-year period to make and sell radio-frequency antenna systems to the U.S. military.

Boulder-based First RF Corp. employees are working on the first order of antennas commissioned in the contract, said Jeanne Hill-Jurik, the company's contract manager. Hill-Jurik declined to discuss details of the order because of the nature of the government contract.

The U.S. Air Force Research Laboratory in Rome, New York, is the contractor. The contract was made through the Small Business Innovation Research program to research, develop, test, evaluate and deploy advanced radio frequency systems, according to a press release.

First RF employs about 110 people at two locations in Boulder: a 30,000-square-foot building at 4865 Sterling Drive and another 30,000-square-foot building at 5340 Airport Blvd.

The private company is a woman-owned business founded in 2003, but the company declined to reveal the name of the owner(s). Since then, First RF has delivered more than 165,000 broadband antennas to customers in government and the private sector, according to information on the company's website.
