Product information
Bring the outside signal in. The Katalyst Siren 2-Lead Antenna strengthens your router’s LTE and 5G connection by capturing clean, stable signal from outdoors and delivering it straight to your device. It’s perfect for improving coverage in metal buildings, rural areas, or other weak-signal environments.
Designed for smaller routers or setups that use 2x2 MIMO, Siren 2-Lead enhances performance without overcomplicating your install. Built for business-grade connectivity, Siren captures a wider range of frequencies than standard antennas and feeds them directly to your router for faster, more stable internet.
Compatible With:
CSG m212, or any 2-lead SMA-compatible 4G/5G router. (choose 2-lead or 4-lead model to match your router).
Key Features
Multiple Mounting Options
Mount it wherever your signal is strongest—on a pole, on a wall, or even on a window with suction cups.
Outdoor-Ready (IP67 Rated)
Built to handle the elements. The Siren Antenna is water- and dust-resistant for year-round outdoor performance.
Tuned for True 5G Performance
Optimized to excel in the upper frequency range where 5G operates—delivering better speeds and stability than standard wideband antennas.
Ultra-Wide-Band Coverage
Covers 410–6000 MHz for compatibility with 5G, 4G, 3G, 2G, Cat-M, and NB-IoT networks.

Can I use this with my existing business router?
Yes, the Siren is compatible with any cellular router that has external 2 or 4 cellular SMA ports.
Can I install it on an RV or trailer?
Absolutely. If you’re off-grid, on the move, or living that remote life, this antenna
can go wherever you can bolt a mount or suction to a window.
Which Siren Antenna do I need for my cellular router?
Count your cellular antenna ports. If your router has 4 LTE/5G ports like the Katalyst SPARK, go with the 4:1 Siren. If it only has 2 LTE/5G ports like the CSG m212, go 2:1. Skip the ports labeled “Wi-Fi” - those aren’t for cellular. Want to install it outside? Go with the SIREN KIT version (comes with a J-Mount and 25ft of cabling)
You say this is compatible with Katalyst Spark, but doesn't that have 6 antennas?
The Spark has (4) Cellular and (2) Wifi antennas. The Siren is only needed to connect to the (4) cellular SMA connections as this only improves cellular signal for cellular-based routers that run on carriers such as Verizon, T-Mobile, AT&T, etc.
Does it matter where the Siren is installed?
If you are installing the Siren on your building, it is recommended to install the antenna so it sits above your roof line for maximum exposure.
What's included in the antenna-only option?
Just the Siren antenna and cables. No J-pole mount, no long install cable. Perfect for
indoor setups or if you already have your own mounting hardware.
Where can I find more performance details?
