RUTM51 - Use ONLY 2x2 MIMO antenna

Bought (by mistake) 2x2Mimo outdoor 11dbi antenna for use with 5G in area with very weak signal. Router have 4 antennas, but no description how they are shared / paired. Lets call them 1-2-3 and 4,

Can I use this high gain antenna on this unit, and benefit from the high sensitivity from the outdoor antenna ? ( It has 2 leads) If yes, which socket should be used, and what about the remaining 2 sockets ?

Next - Is is possible to changet setup of the router to 2x2MIMO ? If yes, which antenna sockets will then be active and which 2 will be disabled ?

Thanks for help :-)!

Good afternoon,

I can confirm that on RUTM51 all 4 mobile antenna ports are main. So there is no difference on which ports you will attach those antennas. On the rest of naked ports I would recommend to still attach the antennas that you have received when you purchased the device originally.

In regards to changing the setup, the device is meant to utilize all 4 antennas, so it should be used like that. You will still benefit from having only one or two antennas instead of all 4, however the signal strength will not be as strong. It will require testing in your circumstance.

As far as I know RUTM51 uses RG500U-EB modem.

Yes, all antennas are main, but different antenna ports can operate on different frequencies

Here is the hardware document from Quectel page:

Hi there,

As far as Teltonika advice goes, the way the device modem is configured, client will benefit connecting it in any order. As mentioned above, it will still require testing in client circumstance, as they are looking to implement a custom solution.

If you go to RUTM51 QSG in our Teltonika Wiki page QSG RUTM51 - Teltonika Networks Wiki

You can see that all connectors are described as mobile antenna connector. This indicates all the connectors being as Main. This also correlates with the device performance.

If you check out another example QSG, let’s say RUT956, QSG RUT956 - Teltonika Networks Wiki

You can see that the connectors are differentiated.

Regards,

Thanks for info.…

Seems that ANT0+2 is a pair, and ANT4+5 is a pair where 4+5 is dedicated 5G/3MHz, while 0+2 covers both low&high frequencies and combine 4G and 5G. Or… :slight_smile: ??
