What's included?
All the essential cables are provided, making the unit ready to install straight out of the box.
One bundle, everything you need
This bundle includes a SubZero 4 Channel UHF Antenna Divider and two directional antennas, along with all required BNC and DC cables. Everything’s designed to work together out of the box, helping you quickly build a reliable UHF wireless system with fewer cables and less setup time. Whether you’re installing in a rack or building a portable kit, the included accessories make the process simple and tidy.
Directional antennas improve signal clarity
The included SubZero directional antennas provide focused UHF pickup with a 75° vertical and 130° horizontal beam width. This improves reception by targeting your wireless transmitters and avoiding stray interference. They’re ideal for live stages and venues where reliable signal is critical. With mic stand adaptors included, they’re quick to deploy wherever you need coverage. Microphone stands are sold seperately and available here.
Streamlined UHF signal and power distribution
The SZ-AD4 antenna divider allows you to share one antenna pair across up to five wireless receivers, while also powering up to four of them. This cuts down on clutter, reduces the need for extra power supplies, and keeps your setup compact and efficient—especially helpful for live shows and touring rigs.
Ready to expand when you are
If you need to scale up, simply link a second SZ-AD4 unit (sold separately here)to expand your setup to nine outputs. You’ll still only need one antenna pair, and your UHF signal remains clean and stable across the system. It’s a flexible solution that grows with your gear, without needing a complete overhaul.
