The radio side is SWIT's own: a KUWI 2.0 Pro chip driven by a closed protocol, not Wi-Fi. Licence-free spectrum at 5.17–5.69 GHz and 5.75–5.83 GHz is used, DFS compliant, with OFDM modulation from BPSK up to 64QAM at 23 dBm. Set to Auto, the system scans the band and hops to a clearer frequency without dropping the image. An RF coordinator at a stadium or trade fair can lock one of 22 manual channels instead; set on the transmitter, it is mirrored by both receivers.

Two menus shape the behaviour. The transmitter switches image quality between HQ and Auto, and that change asks for a restart, best done during setup. Each receiver offers Low Latency or Stable: the second accepts extra delay in exchange for firmer resistance to interference, a sensible pick for a client monitor at the back of a venue packed with networks.

Range comes down to antennas. SWIT quotes roughly 900 m for the stock 3 dBi soft-base antennas. Swapping to the 5 dBi high-gain antennas supplied, a pair for each of the three units, lifts the figure to 1.2 km and steadies the link through partitions. The manual's field advice is simple: antennas upright, receiver raised and facing the transmitter, no walls, trees or water in the path. Add SWIT's CREW MAX panel receiver to the group and the same transmitter serves that position at up to 3 km.

Two receivers are a starting point. One transmitter drives up to four in multicast without giving up distance, latency or picture, and every CREW-family unit, whether NP-F, V-mount or panel type, links to any other. Large sites can run up to eight pairs at once, provided each transmitter has a valid source; white and yellow tags on the antennas show which receiver belongs to which camera.

Cinema crews get the data too. Embedded SDI metadata crosses the link for DIT live grading, alongside embedded timecode and the REC start/stop command, so a recorder at the far end rolls with the camera; the manual cites ARRI bodies here. Protection works on two levels, SWIT's proprietary radio protocol first and AES-256 encryption of the content second, which keeps an embargoed launch or a closed set off unauthorised screens.

Day to day, paired units find each other at power-on. Receivers are paired one at a time, after which the transmitter's bright OLED shows how many are connected, and each receiver displays signal strength, or "unlink" if the path breaks. Every screen also shows the power source and a four-bar battery gauge. Cooling follows internal temperature or can be switched off for silent takes. Updates come from a USB flash drive on the OTG adapter, after which the units are paired again.

All three units share the same power options: an NP-F plate (SWIT suggests NP-F770/970-class packs), a 2-pin LEMO input taking 7–17 V, or USB-C (transmitter 9 V/2 A, receivers 5 V/2 A). Power draw is 16 W at the transmitter and 6 W per receiver, with an operating range between −10 and 40 °C, and a 1/4"-20 thread takes standard mounting hardware. In the case: a D-Tap to 2-pin LEMO lead and a USB-C cable for each unit, the OTG adapter and twelve antenna tags in white and yellow. The transmitter sits in an all-metal housing, made for daily life on a camera rig.
