This enhanced model features two external antennas on the transmitter, one of which is a spare. The transmitter provides a single HDMI input and an HDMI loop-out for onboard monitoring, while the receiver features two HDMI outputs. The transmitter offers line-of-sight transmission up to 400' to the receiver and up to 300' to a Wi-Fi app.

The transmitter can transmit to up to one receiver and two apps simultaneously, or up to three apps in total. Both the transmitter and receiver are equipped with a bright OLED display for configuration and a 1/4"-20 mounting thread. They can be powered via USB Type-C or with an L-series type battery using their battery plates, which are available separately.
