  • Dual band: serves both the 2.4 GHz CRMX and Sidus Bluetooth side and the 5 GHz Wi-Fi side.
  • Four antennas and a storage box per pack.
  • Sidus Four ships with five of these antennas; keep spares on hand to replace a damaged one.

FAQ

Is there a separate receive antenna for wireless DMX?

Sidus Four uses five dual band antennas for all of its wireless links: CRMX and Sidus Bluetooth at 2.4 GHz and Wi-Fi at 5 GHz. This pack holds four replacements for those antennas.

How many wireless universes does Sidus Four send through these antennas?

Four CRMX universes, plus four wired DMX universes through its 5-pin ports. Linking more Sidus Four units over Ethernet adds more.

My lights drop out when the signal gets interference. Do antennas matter?

A damaged or missing antenna shortens range. Sidus Four also splits CRMX at 2.4 GHz and Wi-Fi at 5 GHz to reduce overlap, so keep all five antennas fitted and the unit up high.
