The CW-3 consists of a transmitter with HD-SDI input/output and two RP-SMA antenna connectors, paired with a receiver featuring HD-SDI output only.
A firmware update reduced initial link time from 60 seconds to under 10 seconds after powering on the transmitter.
The unit operates at 5GHz and includes two 90-degree bendable antennas, with RP-SMA connectors allowing external antenna attachment.
Both transmitter and receiver feature indicator lights for link status and video presence, plus 1/4-20 screw holes for mounting on support arms.
The equipment generates moderate heat which can degrade velcro adhesive mounting over time.
Firmware updates are available via Windows PC using a Mini USB connection.
The CW-3 operates as a point-to-point one-to-one system and does not support multicast transmission to multiple receivers.
Progressive segmented Frame format video signals remain problematic for the unit, though the manufacturer was working on resolution at the time of review.
Sony cameras transmitting 59.94p at 1080i in non-PsF format are compatible with the unit.

Review and testing based on 2014-2015 timeframe with firmware updates available at that time.
Price information and product availability cited from that period may no longer be current.
User experience focused on single 1:1 transmission setup without testing multicast scenarios.
PsF compatibility issue status at time of publication was unresolved pending manufacturer updates.
Only external antenna testing mentioned included 5GHz options; other frequency bands not explored in review.
