Frequency Devices was founded in 1968 by Bob Steer and Charles Wing. The company’s first products were signal conditioning and filtering instruments for use on board ships. We continue to make similar products for industry and marine usage. In 2007 Frequency Devices was purchased by Bill Franklin Jr., K9EIF, and his son Bill Franklin III and relocated to Ottawa, Illinois. We are now branching out to Ham Radio products starting with wire antennas. We will be adding more products over time so check back often to see what is new.
