How do I know if I should choose 2x2 or 4x4 antennas for my site?

Cellular Antennas and MIMO · 2026-10-02

Antenna count depends on the router's MIMO capability and the bands you need to support. Two antennas are common for 2x2 MIMO, four for 4x4. The SIM count does not automatically map to RF paths. Check your model's recommended antenna arrangement and the bands you will use at your site. Ensure you follow the model's guidance for antenna spacing and connection types, and remember that more gain isn't always better if site conditions or cables introduce losses. To decide for your site, compare the model's documented guidance with your measured conditions. If you're unsure, share your site conditions with Comset and we can point to the model's documented guidance and typical best-practice configurations.
