I am currently using a RUT240 gateway with two Wittenberg LAT56 Duo antennas connected. I would like to migrate this setup to a TRB500 gateway and would like to know which SMA connectors on the TRB500 are used for 5G and which are used for 4G.
I have reviewed the TRB500 manual, but it does not include a description of the antenna connections, nor are they labeled on the device itself.
Can I continue using my existing antennas and add separate 5G antennas, or do I need to replace them with a 4x4 MIMO antenna setup?
If anyone could clarify this for me, I would greatly appreciate it.
TRB500 has the same modem as RUTX50 (silver version), Quectel RG501Q-EU
Connect the two external antennas to the first two left SMA ports when looking at the router from the back (the link posted by member Marcelo.Barros is outdated)
For 5G you need an antenna that supports both 700 MHz (band 4G B28 or 5G n28) and 3600 MHz (in the EU it is band n78)
If you have 5G bands (e.g. n28), this modem has problems with aggregation and you must have 4 antennas connected. If you only have 4G bands, then it will work smoothly with two antennas connected.
I use Iskra P-60 MIMO antennas, they cover all 4G/5G frequencies and are the best.
If your tower has 4x4 MIMO which means 50-75% higher speeds, you need to buy another pair of Iskra P-60 MIMO (4 antennas in total and mount them correctly and pay attention to the spacing between the antennas, eg I use 34 cm between antennas for B3 band as the golden mean).
These antennas must be as high as possible and pointed at the tower for the best signal and speeds (if the tower is not loaded).
