The Williams Sound ANT 025 is a 39-inch telescoping whip antenna designed for compatible Williams Sound and Williams AV 72–76 MHz FM assistive listening transmitters. It provides a convenient replacement antenna for large-area FM listening systems used in houses of worship, theaters, schools, conference facilities, and other public venues.
Featuring an adjustable telescoping design, the ANT 025 attaches directly to the compatible transmitter's threaded antenna mounting stud. Its 39-inch extended length provides an antenna solution for installations where direct transmitter mounting is appropriate.
The ANT 025 is compatible with several Williams AV Personal PA transmitters, including the PPA T45, T55, T55C, and T27. Older Williams Sound documentation also identifies compatibility with the PPA T35.

Designed for FM Assistive Listening Systems
The ANT 025 is intended for large-area Williams Sound FM transmitter systems that distribute audio wirelessly to compatible personal listening receivers.
These systems are commonly installed in houses of worship, auditoriums, classrooms, theaters, and meeting facilities to help listeners hear speech and program audio more clearly.
The ANT 025 provides a direct-mounted antenna option for supported transmitters. Antenna placement, transmitter location, building construction, and RF conditions can affect overall system coverage.

Installation Considerations
The ANT 025 is intended for direct attachment to a compatible transmitter rather than use as a remote-mounted antenna.
Proper installation and antenna positioning are important for reliable FM system operation.
Important: Williams AV states that FCC regulations require professional installation of this antenna. Follow the manufacturer's instructions and applicable transmitter-specific antenna length restrictions.
For installations requiring an antenna located away from the transmitter, a compatible remote antenna system may be more appropriate.
