It looks like you are listing the exact inventory for the Hollyland Syscom 421S (4TX to 1RX) Wireless Video Transmission Bundle.
This is a powerhouse setup for multi-camera live productions, sports broadcasting, or live streaming. That high antenna count ($25\times$) often catches people off guard, but it's completely correct for this specific package.
Here is a quick breakdown of what this kit gives you and why it’s configured this way:
System Breakdown
-
4x Transmitters (TX): Each camera gets its own dedicated transmitter. They support both SDI and HDMI inputs and send uncompressed 1080p60 video up to 1,800 feet (550m) line-of-sight.
-
1x Receiver (RX): A single central hub that receives all 4 video feeds simultaneously on one RF channel. It features 4x SDI outputs and 4x HDMI outputs to route straight into your video switcher or production monitor.
-
25x 5GHz Antennas: Both the transmitters and the receiver require 4 antennas each to operate (4 antennas x 5 20 antennas in active use). Hollyland includes 25 in this specific bundle to ensure you have 5 backups on hand for the field.
-
4x Arm Mounts (7-inch Magic Arms): Used to securely mount each of the 4 transmitters onto your cameras' cold shoes or cages via 1/4"-20 threads.
Production Features Built-In
-
Ultra-Low Latency: Clocking in at just 0.07 seconds, keeping your cuts tight and in sync during live broadcasts.
-
PTZ & Tally Control: It passes RS422/RS485 control signals and Tally indicators back and forth through the wireless link, meaning you can control PTZ cameras remotely and trigger "on-air" lights seamlessly.
-
RTSP Streaming: The receiver has an RJ45 LAN port, allowing you to push or pull direct network streams for local monitoring or web streaming.
