EMR Corporation was founded in 1980 by William Lieske, Sr. as an OEM supplier of ferrite and hybrid devices to the land mobile communications and broadcast industries. Until his passing in 2007, Bill was involved in radio communications for more than 70 years. Beginning with a radio amateur license at the age of 13, he went on to work in military radar, public safety, radio communication manufacturing and commercial corporate sales. As the chief engineer, Bill's approach to R.F. systems component design was without parallel in the industry. Bill's work has helped set standards in the U.S. and international land mobile communications and antenna site management industries.
Soon after founding EMR Bill expanded his scope of activities to include the design and manufacturing of ferrite and cavity resonant devices and complex combinations of R.F. filtering products, such as antenna duplexers, hybrid and cavity resonant combining networks and receiver multicoupling.
In early 1992, EMR began manufacturing amplifiers for land mobile and broadcast receiver applications. EMR's product line now includes a line of receiver pre-amplifiers, hybrid dividers and amplifiers in various bands for up to 250 watts output power. as well as advanced product for in-building signal enhancement applications and web based antenna site monitoring.
