Nick Paulin, ERI Product Engineering Manager, presented an expanded version of his NAB Broadcast Engineering and Information Technology Conference (BEITC) paper at ERI’s 26th Annual NAB Broadcaster’s Breakfast held on April 11, 2018 during NABSHOW2018 in Las Vegas. This presentation provides an overview of the design process and considerations for designing an FM channel combining system that can allow 19 FM Radio stations operating with -10 dBc IBOC simultaneously from a master FM antenna and combiner system. The antenna, transmission line, and combiner design criteria are discussed and the Empire State Building Auxiliary Master FM Antenna and Combiner system are highlighted.

President and CEO of ERI, Tom Silliman, presented ‘Signs of End of Life: FM Antennas and Transmission Line Systems’ at the 2018 Public Radio Engineering Conference. His paper and presentation explored the indications and symptoms of FM antenna and transmission line systems that require replacement as they are at or near end of life. The paper included a discussion of symptoms of system impairment, recommended inspection procedures and methods, system test and measurement procedures and interpreting their results, and environmental and structural support circumstances that impact antenna and transmission line system life.

Chandler, Indiana USA – April 3, 2018 – Electronics Research, Inc. (ERI) will show a new series of adjustable directional couplers that feature external terminations. This family of coaxial directional couplers that are adjustable and externally terminated. The orientation of any sampling port can easily be changed from forward to reflected by reposition the external termination load on the coupler.
These couplers are available in 3-1/8-inch, 4-1/16-inch, and 6-1/8-inch, 50-ohm, models, with flanged input and output connections. The 3-1/8-inch and 4-1/16-inch models are also available with an unflanged male connection at the coupler input. Models available with one to five adjustable couplers with Type N sample ports. One external termination load is supplied for each sample port. Directivity and coupling level are dependent on operating frequency. The design of this new product family is complete, and all items mentioned in this release are in current production.
