Product Overview
Latest-generation medium RF chamber — ≥70 dB isolation in a desk-top footprint
Latest revision of the medium-sized 70+ dB RF chamber.
The CT820c is the latest revision of our medium-sized affordable RF
enclosure family (CT820a / CT820a-hf / CT822a). Sized to fit most APs,
Wi-Fi devices and instrument tools on a typical bench, with ≥70 dB of
RF isolation across 800 MHz – 8 GHz.
Comes with a full set of filtered interfaces (SMA, 10 GbE, USB, optional
HDMI / coax / fiber) and a universal A/C power strip inside. Engineered
for daily Wi-Fi 6E / Wi-Fi 7 testing where chamber repeatability matters
more than carrier-grade isolation.

/// Software Features
RF & Network Interfaces
- •16+ filtered SMA ports (32 on the larger 'b' chambers).
- •3× filtered 10 GbE Ethernet pass-throughs per chamber.
- •USB-A 3.0, USB-A 2.0 (optional) and USB-C pass-throughs.
- •Optional 4K HDMI, RF Coax (Type-F) and FC fiber filtered ports.
- •Universal A/C power strip inside every chamber.
- •Optional DC-jack pass-through for chamber-internal power.
Frequency & Isolation
- •Designed for 800 MHz – 8 GHz operation, optimised for the 2-6 GHz Wi-Fi range.
- •'a'-series: ≥70 dB RF isolation (most affordable; great for everyday Wi-Fi work).
- •'ss' stack chambers: ≥80 dB RF isolation (mid-tier).
- •'b'-series: ≥90 dB RF isolation (full Wi-Fi isolation even with all RF filters in use).
- •RF-absorbing internal lining: ≥4.5 dB at 2.4 GHz, ≥10 dB at 5 GHz on 'a' models; ≥18 dB across 1.3-18 GHz on 'b' models.
Automation & Integration
- •Programmable 2D turntable (and 3D positioner option) on larger chambers — driven directly from LANforge.
- •API-controlled fan and door / light switches on supported models.
- •Integrated LED lighting and an internal camera on Large and Stack chambers.
- •Antenna mounts and high-gain directional antennas on Large and Stack chambers.
- •Front-loading doors with stack-friendly form factors.
/// Hardware Specifications
- Welded steel construction with conductive RF gaskets and filtered penetrations.
- Forced-air ventilation with filtered intake/exhaust to keep DUTs cool.
- Universal A/C power strip inside the chamber.
- Front-loading door with quick-release latches; stackable with matching chambers.
- Customisable port configurations — tell us your DUT and we'll wire the chamber to match.
- Outside dimensions ≈ 550 × 650 × 535 mm (matches the 'a' generation footprint).
- Inside dimensions ≈ 480 × 490 × 480 mm — fits all common APs and most laptops.
- Approximate weight: 30 kg (66 lb).
