Sound Devices A20-2.4 Ant+Mount

Antenna and Mount Kit for Bag-Based A20-Nexus Operation
The Sound Devices A20-2.4 Ant+Mount is a purpose-built antenna and mounting solution for users running the A20-Nexus in a portable bag setup. This kit enables external mounting of the 2.4 GHz NexLink antenna to the side panel of the A20-Nexus, allowing the antenna to extend cleanly out of the top of the bag for optimal RF positioning and NexLink control reliability. It's the ideal accessory for sound mixers and location recordists who require stable wireless control in dynamic, on-the-go environments.

Designed for NexLink Wireless Communication in Portable Rigs
This kit supports Sound Devices’ proprietary NexLink protocol by providing a reliable 2.4 GHz signal path when traditional rear-mounted antennas would be obstructed. By repositioning the antenna to the top of the bag, the A20-2.4 Ant+Mount helps maintain strong bi-directional communication between A20-Nexus and compatible transmitters like the A20-TX and A20-Mini.

Flexible Mounting for Left or Right Side Installation
The included adjustable bracket is engineered to attach securely to either side panel of the A20-Nexus, giving users flexibility based on bag layout and access preferences. It brings the antenna forward and upward, extending it above other gear in the bag for maximum exposure and better RF line of sight—especially useful in crowded or reflective RF environments.

Includes High-Quality RF Cable and Mounting Hardware
Along with the tilt-adjustable bracket, the kit includes a 45 cm (18-inch) RG58 SMA-M to SMA-M RF cable for reliable signal transfer, as well as an SMA-F coupler to bridge the receiver's rear panel port to the bracket. The included mounting hardware and Allen keys make installation straightforward, allowing for secure and professional assembly without additional tools.

Space-Saving Antenna Mounting Without Compromising Performance
This solution is ideal for field setups where space is limited and RF performance must remain consistent. Rather than bending or repositioning fixed antennas inside the bag, this mount allows for stable, repeatable positioning every time the kit is deployed. The tilt function also lets users fine-tune antenna orientation to suit real-world interference and bag layouts.

Engineered for Durable Field Use and Long-Term Reliability
All components in the A20-2.4 Ant+Mount kit are built to withstand regular use in mobile recording environments. The bracket is solid, the cable is shielded and flexible, and the connectors are matched for secure RF contact. It’s a professional-grade upgrade for any A20-Nexus system configured for portable production workflows.

A Complete Solution for External NexLink Antenna Mounting
With everything included to route and reposition a single NexLink antenna, this kit delivers an essential piece of gear for wireless audio professionals who rely on remote transmitter control in mobile production environments.
