Williams AV ANT 024 – Wall-Mount Dipole Antenna for FM Systems

Product Overview

The Williams AV ANT 024 is a 75-ohm wall-mount dipole antenna for 72–76 MHz large-area FM assistive listening transmitters, including the PPA T45, PPA T55, PPA T55C, and PPA T27. With both whips extended, the dipole measures 40 inches and provides stronger, more predictable FM coverage than a chassis-mounted whip, making it the preferred remote antenna for auditoriums, houses of worship, and other large venues. A 20-foot RG-59 coaxial cable is included for connection back to the transmitter, and the FCC requires this antenna to be professionally installed.

Product Description

When an FM assistive listening transmitter sits in an equipment rack or control booth, its onboard antenna is often blocked by metal racks, walls, and other equipment — a common cause of dropouts and weak reception on FM receivers in the seating area. The ANT 024 wall-mount dipole antenna addresses this by moving the radiating element out of the rack and onto a wall with clear exposure to the listening area. Its balanced dipole design delivers more efficient radiation than a simple whip, improving signal strength and coverage uniformity across large rooms.

Installation is straightforward for a qualified AV integrator: mount the dipole to the wall, extend both whips to the full 40-inch length, and run the included 20-foot RG-59 coax back to the transmitter F-connector. Because the FCC requires professional installation of this antenna, plan it as part of the overall assistive listening system design rather than as a user-serviceable accessory. The ANT 024 pairs naturally with large-area FM platforms in our Williams AV assistive listening collection, including current FM+ systems such as the Williams AV FM 557-12 dual FM and Wi-Fi system, helping facilities meet ADA hearing assistance requirements with dependable coverage.

Frequently Asked Questions

Which Williams AV transmitters work with the ANT 024?

The ANT 024 is specified for the PPA T45, PPA T55, PPA T55C, and PPA T27 large-area FM transmitters, all operating in the 72–76 MHz assistive listening band. It connects via a standard F-connector using the included RG-59 coax.

Why use a remote dipole instead of the transmitter's built-in antenna?

Transmitters installed in racks or control booths are often surrounded by metal and structural obstructions that attenuate the FM signal. Mounting the ANT 024 on a wall with clear exposure to the seating area improves signal strength and reduces dead spots for listeners on FM receivers.

Does the ANT 024 require professional installation?

Yes. The FCC requires this antenna to be professionally installed. A qualified AV integrator should select the mounting location, route the coax, and verify coverage as part of the assistive listening system commissioning.

Can I extend the cable run beyond 20 feet?

The ANT 024 ships with a 20-foot RG-59 cable. If your transmitter location requires a longer run, consult your integrator about acceptable coax extension practices, since added cable length introduces signal loss that should be accounted for in the system design.

What warranty and support apply?

The ANT 024 carries a 90-day manufacturer warranty. Creation Networks can assist with compatibility questions and with specifying the complete Williams AV FM assistive listening system around it.
