Antenna count is tied to the router MIMO configuration and the bands you need to support. Two antennas are common for 2x2 MIMO, while four may be used for higher-performance 4x4 MIMO. The number of SIMs does not automatically map to number of 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 recognize that more gain isn't always better if the site conditions or cables introduce losses. 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.
