Product Information on Private Labeled FM Antennas
Electronics Research, Inc. is the designer and supplier of the most popular FM antennas in use today. ERI FM Antennas have been supplied to the major producers of FM broadcast transmitters as private labeled products. The private labeled antennas were marketed by initially by Collins Radio, then a division of Rockwell International, and later the Gates Radio Company, owned by Harris Intertype Corporation. Collins was acquired by Continental Electronics and continues to offer ERI manufactured FM antennas as does Harris Corporation's, Broadcast Communications Division (formerly Gates Radio). ERI has also private branded antennas for many years for Broadcast Electronics.
