AC1224-240
~240 × 240 cm (8 × 8 ft) walk-in anechoic chamber
The AC1224-240 is the standard-cross-section chamber in the AC1224 family. At roughly eight feet by eight feet, it sits in the practical middle ground for walk-in mmWave test chambers. AC1224-240 is large enough to work inside, and compact enough to fit into office locations.
EXACTLY WHAT YOU NEED. NOTHING MORE.
Right-sized for mmWave
The AC1224-240 is designed from the ground up for mmWave. No legacy overhead, no repurposed low-frequency construction. The result is a chamber that performs where it matters and at a fraction of the cost of a full-metal anechoic chamber.
Most walk-in anechoic chambers on the market from the high-end brands were originally designed for lower-frequency work, and they carry the engineering costs that come with it: welded steel enclosures, heavy shielding, expensive assemblies. They are truly excellent chambers, but if your typical application lives at X-band and above for radar cross-section (RCS) measurements, antenna pattern characterization, 5G FR2 device testing, and beamforming applications, that is performance you are unlikely to need, which makes the AC1224-240 worth a closer look.
AC1224 CHAMBERS – KEY ADVANTAGES
Modular solution for mmWave
User-installable
Every panel and beam can be carried by two people. The heaviest panel weighs 24 kg. Assembly requires only hand tools: no cranes, no contractors, no waiting. A chamber your team has built is a chamber your team understands.
Fits where others cannot
An all-aluminum frame and lightweight panels keep the floor load as low as 60 kg/m². The AC1224-240 installs in attics, basements, raised floors, and older buildings that would never support a conventional chamber.
A CHAMBER FOR EVERY ROOM
Fits where other chambers cannot
The AC1224-240 goes where traditional chambers cannot. An all-aluminum frame and lightweight panels keep the floor load low, making it a practical choice for lofts, raised data center floors, and older buildings that would never support a welded-steel chamber.
One AC1224-240 is running in an attic in Silicon Valley, a location where commercial rent rates make every unused room an expensive liability. That chamber turned otherwise wasted space into a functioning test range.
Another AC1224-CUSTOM is installed in a low-ceiling basement beneath a Scandinavian laboratory, a space that would have ruled out any conventional chamber. Because panels are installed from the inside, the custom chamber could use the room effectively and fit with only 25 mm (1”) distance to each of the walls.
DESIGNED TO BE BUILT BY YOU
User-installable
All AC1224 chambers are designed to be handled by a small team of installers; two people will typically suffice (three makes it easier). The heaviest panel, with 115 mm absorbers fitted, weighs 24 kg. Assembly requires only hand tools, except the panel hoist, which is provided in the shipment.
Having your team install the chamber, or at least participate in the installation process, is a valuable experience: a chamber your team has built is one your team understands. Future reconfiguration, relocation, or expansion becomes something you handle on your own schedule, without dependencies on third-party movers.
The AC1224 family was deliberately designed from the ground up to deliver what we believe is the lowest lifetime cost of ownership of any walk-in chamber on the market.
The image above is from a relocation of an AC1224-240-5 from the original location in the customer’s attic to their new facility in Silicon Valley. It took 2.5 days, and you can read more about it here.
CHOOSE YOUR CHAMBER
AC1224-240 Configurations
Each AC1224-240 chamber is built from door, center, and end modules. If you need access from both ends, you can have door modules in both end of the chamber. The length/depth of the chamber is defined by the number of modules you choose to add.
An overview of external and internal dimensions for different configurations is available below. Contact us for further details.
*Exterior dimensions (height) include ~5 cm (2″) adjustable feet that may be removed if more clearance is needed. Contact us to discuss further.
TOOLS AND EQUIPMENT
AC1224-240 assembly
The chamber comes with complete assembly instructions. To build an AC1224-240 (any length) chamber two people are required, three are preferred.
Hand tools and equipment included in the shipment: Allen/Unbraco bits size 4 mm and 5 mm, adjustable wrench, bit extender 150 mm, carpenter’s square, drywall hoist with correct height for ceiling panel placement.
Extra hand tools required: Electric drill, laser level, inclinometer (if we are leading the assembly we will bring the extra required hand tools).
Extra equipment required: Tall ladder to reach over the chamber (top-step around 3 meter).
EFFORTLESS ADAPTATION
Designed and manufactured by mmWave Test Solutions
All AC1224 chambers are designed and built by mmWave Test Solutions. Production runs in-house or through qualified suppliers, but design authority and manufacturing control always stay with us.
That we have full control over design and manufacturing matters when you need something slightly outside the standard. Cutouts for vent ports, mounting points for cameras or CCTV, concrete-floor-anchored pedestals: smaller modifications like these we can usually accommodate without moving to a full custom project.
We have made numerous tiny and enormous customizations in the past (that are not on our web pages), so if you have questions or ideas, please get in touch and let’s see how we can help you.
