ERI said it is now taking orders for its dual-input side-mounted FM antenna designed for FM IBOC applications. The product won a Radio World “Cool Stuff” Award at last week’s NAB show, where it was unveiled.
The antenna can transmit the analog and digital FM signals without requiring a high-loss hybrid combiner or a circulator to attain the required isolation between the digital and analog transmitters.
ERI says the design meets the FCC requirement for informal notification of IBOC implementation that all the elements in an FM antenna array be excited by both the digital and analog FM signals.
