The DJI Phone Holder for SDR Transmission Receiver allows you to easily view footage from an SDR transmission transmitter on set. To use, simply open the spring-loaded clamp to insert your phone, attach your SDR transmission receiver using the back 1/4"-20 thumbscrew, and connect them with the included USB-C or Lightning cable. Once set up, you can view streaming footage by holding the system or mounting it to a tripod using the bottom 1/4"-20/cold shoe combo connector.
