RUTM30 with 2x2 MIMO antenna

Hi,

I have a new RUTM30 unit I will install in a location that (currently) only has an external 2x2 MIMO antenna. Which 2 of the 4 mobile antenna connectors should I connect the external antennas to? The connectors are all marked the same on the unit chassis.

I found several answers in the forum for RUTX50 but none for this model, which has a different modem inside.

Greetings,

All four mobile antenna ports are classified as MAIN ports.

  • On the RUTM30, ANT0 and ANT5 are TRX (Transmit/Receive) ports.
  • The middle ports, ANT2 and ANT3, are DRX (Diversity Receive) ports. These improve signal reception but do not transmit.
  • For optimal performance, we recommend connecting antennas to all four ports.
  • If only two antennas are used, connect them to ANT0 and ANT5, as these ports support both transmission and reception (TRX).

Hello, I own a RUT955 and want to upgrade to the RUTM30. I have the following antenna connected to the RUT955: 003R-00253 Can I use this antenna with the RUTM30? Which antenna connectors on the RUTM30 would be best to connect to the roof mounted antenna? For the remaining two antenna connectors, I will use the included flat antennas. Wondering which combination of “indoor small antennas” + roof mounted antenna will be best, across ANT0, ANT2, ANT3 and ANT5.

@krl could you please create a separate topic regarding this question?

I’d advice - from experience - against not having identical antennas for all connectors. The setup I tried caused modem resets during heavier network traffic. The issue was fixed by replacing the two included antennas with identical outdoor yagis (4x4 MIMO with 4 Iskra P-60).
