Will it use both antenna connections or will it only use one?<BR /><BR /></P><P>I have a situation where i have two antenna (in a Cisco 4G-LTE-ANTM-O-3-B) with each connected to either the MAIN or DIV signal inputs. I get no workable signal when plugged one way, but high signal if i swap the cables around. Clearly something is wrong, but I wondered if there was any benefit in fixing the second connection anyway, or should I look at upgrading the antenna to a MIMO one.</P><P>&nbsp;</P><P>Does anyone know?</P> Mon, 05 Jul 2021 18:19:05 GMT https://community.cisco.com/t5/wireless/diversity-on-4g-lte-network-interface-modules-wireless-wan/m-p/3959116#M201611 JasonChatterton52867 2021-07-05T18:19:05Z https://community.cisco.com/t5/wireless/diversity-on-4g-lte-network-interface-modules-wireless-wan/m-p/3959247#M201612 Best thing is, upgrade to a Wi-Fi MIMO antenna. <BR />Also that antenna doesn't support the 5 GHz frequency, so you'd be advised to turn it off on the AP.
