The RUTX50 modem has two sma connectors for connecting Wi-Fi antennas and I want to improve the coverage of the Wi-Fi connection and connect a stronger antenna to one sma connector, Alfa 2.4GHz Outdoor Omni Antenna 15dBi N-Female .I want to ask if this antenna is suitable for connecting to the modem RUTX50 sma connection to improve Wi-Fi connection coverage? Does it matter which of the two sma connectors I connect the Alfa 2.4GHz Outdoor Omni Antenna 15dBi N-Female to?
Certainly, you can use a higher dBi antenna, but it’s important to consider a few things:
- Make sure the physical connectors (e.g., SMA, RP-SMA) on the antenna match those on your Teltonika device.
- Check if the antenna complies with regulatory standards. In some areas, using high-gain antennas may be regulated, so be aware of and follow local rules regarding radio frequency (RF) equipment.
- Keep in mind that the antenna may not perform as expected since it hasn’t been tested on our devices, especially a high dBi gain antenna.
- You should look at compatibility with frequency bands. Ensure that the higher dBi antenna is compatible with the frequency bands used by your Teltonika device. The antenna’s specifications should match the operating frequencies of your device to optimize performance.
- Higher dBi antennas often provide increased gain, but it’s essential to understand that higher gain may result in a narrower coverage area. Consider the specific coverage requirements of your application to avoid potential issues with signal range and distribution.

You did not answer the question about the modem RUTX50 Wi-Fi two sma connectors. Do they both work identically (signal transmission and reception and frequencies)
Indeed, both of them perform the same function. They both receive and transmit data.
Then I think that one Wi-Fi antenna (supplied with the RUTX50 modem) would provide a wider signal coverage, while the other would provide a Wi-Fi signal for objects further away.
Here is the specification of this antenna:
Frequency 2.4GHz ~ 2.5GHz
Impedance 50 Ω
Is it suitable for connecting to the Wi-Fi connection of the RUTX50 modem?
The antennas included with the RUTX50 are identical, as shown below:
They have the following specifications:
You might be considering using an antenna with a higher dBi value. However, it’s important to note that a higher dBi value doesn’t necessarily mean universally better coverage. Antennas with higher gain (e.g., 7 dBi, 9 dBi) typically offer improved coverage for distant devices, while antennas with lower gain (e.g., 2 dBi, 5 dBi) are better suited for devices in close range. This is because the antenna port receives the same signal power.
It’s worth mentioning that we haven’t tested our routers with 15 dBi antennas, as they weren’t designed for use with such high gain antennas. While they may work, to accurately assess coverage and other specifications, we recommend conducting your own tests.
To add antenna you are reviewing has different not compatible connector to our router, you’d need solution for that. Additional point: these antennas are only suitable for 2.4GHz, while RUTX50 support 2.4GHz and 5GHz Wifi.
