Intel Dual Band Wireless-AC 8265 kit antennas, which antenna is for 5Ghz?

[AVarg12]

I am installing the Intel Dual Band Wireless-AC 8265 desktop kit in a Dell micro PC that only has room for one antenna. Our PC's connect via 5Ghz. The M.2 antenna card has connections for two antennas, labeled 1 and 2. Which one do I use for best 5Ghz results.

Hello AVarg12, Thank you for posting on this Community. Both antenna connectors can be used for Wi-Fi supporting 2.4 GHz and 5 GHz bands. The difference is that both Wi-Fi and Bluetooth radio shares the same antenna. Antenna Connector Functionality for Intel® Dual Band Wireless-AC 8265 Desktop Kit. Antenna 1 (Aux) Wi-Fi + BT Antenna 2 (main) Wi-Fi It is worth mentioning that the Intel® Wireless adapter requires a motherboard with an M.2 key E connector for wireless. Since the computer was assembled by Dell*, we recommend contacting them before performing any integration due to Regulatory Information Regarding Wireless Hardware Installation or Upgrade. https://www.intel.com/content/www/us/en/support/articles/000005687/network-and-i-o/wireless-networking.html You can also review the Integration Guide for Intel® Dual Band Wireless-AC 8265 Desktop Kit https://www.intel.com/content/dam/support/us/en/documents/network-and-i-o/wireless-networking/8265_DT_Integration_Guide.pdf I hope you find this information helpful.

I would add the following to Wanner's recommendations. The AC 8265 WiFi adapter is designed for the MAIN (2) antenna to handle WiFi communication and the AUX (1) antenna to handle both WiFi + Bluetooth. Since BT uses 2.4 GHz band, the 5GHz antenna should be connected to the MAIN (2) connector.
