Frequently Asked Questions
What's the difference between 2-1 and 4-1 Siren antennas?
What's the difference between 2-1 and 4-1 Siren antennas?
2-1 has two leads (MIMO 2x2), 4-1 has four (MIMO 4x4). More ports = more data channels = better performance. Match it to the number of external antenna ports on your router.
Can I install it on an RV or trailer?
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?
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)
Will the Siren help if I have bad reception indoors?
Will the Siren help if I have bad reception indoors?
Yep. If you’re using a cellular router and getting garbage signal, Siren helps pull in stronger LTE/5G signal from outside.
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?
