Can I install only one antenna on RSR820-T? - Ruijie Community

It is recommended that two antennas be installed. The device has two antenna interfaces: ANT0 and ANT1 for installing the main antenna and auxiliary antenna respectively. The main antenna receives and transmits signals, whereas the auxiliary antenna only receives signals. By default, the antenna on Interface ANT0 is the main antenna. If you need to install only one antenna, you are advised to install it on Interface ANT0.
