Shure AXT644 Directional Antenna for AD610 ShowLink (2.4 GHz)

$110.00

"Designed for professional applications in which you need reliable wireless sound, the Shure AXT630 is an Antenna Distribution System capable of handling high signals without distortion, even in the most inconvenient RF environments. This unit sports selectable 60 MHz input filters to match with the available bands from Axient transmitters, thus offering protection against out-of-band signals and ensuring a low overall RF noise floor.

The unit sports four pairs of BNC antenna outputs to distribute its filtered signal to receivers. You'll also note the unfiltered RF cascade ports to connect to wideband devices, such as the Axient Spectrum Manager. The AXT630 can also network to other units by means of its Ethernet connections, so that you can control filtering ranges, antenna power, and attenuation over Shure's WWB6 software. Controls are also easily managed via the front-panel interface.

This powerful unit is constructed to fit into an audio rack, taking up only 1 RU of space. Included with the AXT630 are a 2' coaxial antenna cable, an IEC power cable, and IEC extension cable, as well as Ethernet cables, a hardware kit, and shorter coaxial cables."

About the Shure AXT644 Directional Antenna for AD610 ShowLink (2.4 GHz)

The Shure AXT644 is a specialized directional antenna designed to optimize the performance of the ShowLink two-way communication system used with Shure's high-end wireless microphone platforms like Axient Digital. ShowLink operates in the 2.4 GHz ISM band to provide a robust, low-latency control network, enabling remote adjustment of transmitter parameters such as frequency, gain, and power from the receiver or system manager software. The AXT644 antenna's primary function is to increase the range and reliability of this control link by focusing its reception and transmission pattern toward the transmitters on stage, effectively "spotlighting" the ShowLink signal for a more stable connection in large or challenging venues.

This antenna employs a directional design, typically utilizing a panel or patch antenna configuration, which provides significant gain in a forward-facing lobe while rejecting signals from the sides and rear. This focused pattern improves the signal-to-noise ratio of the ShowLink communication, helping to overcome obstacles like distance, physical obstructions, or interference from other common 2.4 GHz devices such as Wi-Fi routers and Bluetooth systems. By ensuring a robust control link, the antenna helps maintain the system's advanced features, including real-time monitoring, remote muting, and coordinated frequency changes, which are critical during live events where physical access to transmitters is impossible.

The antenna is built for professional touring and installation, featuring a durable housing and standard mounting options such as a microphone stand thread. It connects to compatible ShowLink access points, like the AD610, via a RP-SMA connector. Its use is particularly recommended in complex RF environments, very large venues like stadiums or arenas, or installations where the ShowLink access point cannot be placed in close proximity to the performance area. By extending and solidifying the control network, the AXT644 directional antenna enhances overall system manageability and reliability, safeguarding the critical remote control functions of a professional wireless audio system.
