Just purchased our first Teltonika product the RUTX50 and we are confused regarding the 4 mobile antenna ports which are all just labeled ‘Mobile’.
We assumed - quite possibly wrongly - that the 4 ports were allocated 2 / SIM, but results from tests seem to indicate this isn’t the case. Could anybody highlight how the 4 mobile antenna ports are allocated to the dual SIMs please as I can’t find anything in the manual that confirms the configuration.
We are using the RUTX50 in a vehicle in a rural area. We have 2 Sharkie type antennas on the roof plus 1 antenna on a 9m telescopic mast also on the roof, and so were going to connect 3 ports to those and a 4th port using the rabbit ear antenna directly on the router itself.
Any advice would be most welcome thank you.
in the old forum there was an answer regarding your question as follows:
RUTX50 employs all four antennas as main, meaning that there is no separation of connectors
between 4G or 5G.
Whether to operate on 2x2 or 4x4 MIMO is determined by the modem, based on the received signal
characteristics from all four channels, thus selectively connecting a 5G directional and a 4G omni
may not result in your desired output. Then again, you can still try to connect the Poynting antenna and
attach omnidirectional ones to the remaining connectors.
Besides, the device would still operate in either 4G or 5G at a single instance. I would suggest to test
setups for 4G and 5G and see, which yields better performance.
Also, RUTX50 uses a LTE Cat20 modem and, in order to fully utilize its capabilities, all four antennas are
preferred with identical features.
Hope that helps.
Thanks for taking the time to respond, that is really helpful thank you.
For what it is worth. I have the same router and a poynter 5G antenna (only 2 poles).
Initially I used the 2 inner SMA’s for the antenna and the rabbit ears for the outer ones.
But stability was very very poor. Low speeds and often no connection at all. Swapping it didn’t help either.
As a matter of trial I bought 2 sma splitters for less the 10€ and connected the antenna with the 2 connections via the splitters to the 4 sma connectors on the router and the effect was amazing. A huge step in stability and a far better speed. I have N28 or N78 (low and high 5G frequencies) available. On N28 I have an upload/download speed of about 50/50 mbps. On N78 it’s more like 200/50 Mbps. Before I was already happy with 10/10 Mbps.
I had this same issue with my RUTX50, how to connect up antennas and did it matter?
After asking here i was informed that Mobile ports 1 and 3 should be considered a pair and likewise 2 and 4 a second pair.
Connect matching antennas to each pair, and 1 and 3 are higher frequency ports and 2 and 4 are lower frequency ports.
So if you have a 5G antenna with two sma cables, these should connect to mobile ports 1 and 3.
4G sma cables to mobile ports 2 and 4.
If you have 4 sma cables from 5G antennas, then a pair to 1 and 3, and a pair to 2 and 4.
Antennas should ideally match as pairs.
