Dielectric Interleaved FM Antenna Combines HD, Analog

Dielectric Communications is marketing the new HD Plus FM antenna, which the company says offers the level of analog and digital signal isolation necessary for IBOC broadcasts without the isolator required by most separate antenna systems.
HD Plus can be integrated alongside existing analog FM antennas, it said, allowing the station the ability to continue its analog broadcast while also adding a digital broadcast of the same signal at the same frequency.
The company said its design considerations between the analog and digital antenna bays provide for isolation that exceeds 40 dB, while the FCC requires 36 dB.
