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?
Which Siren Antenna do I need for my cellular router?
Count your cellular antenna ports. If your router has 4 LTE/5G ports like theKatalyst SPARK, go with the 4:1 Siren. If it only has 2 LTE/5G ports like the CSGm212, 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-Mountand 25ft of cabling)
You say this is compatible with Katalyst Spark, but doesn't that have 6 antennas?
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?
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?
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.
