You may use third-party antennas with Teltonika-Networks devices. However, the antennas must meet these requirements:
* '''Antenna connector''': SMA male for 3G/LTE and RP-SMA male for WiFi
* '''Antenna connector''': SMA male for 3G/LTE/5G and RP-SMA male for WiFi
* '''Input impedance''': 50 Ω
* '''Input impedance''': 50 Ω
* '''Minimum input power''': 2W for 3G/LTE and 1W for WiFi
* '''Minimum input power''': 2W for 3G/LTE/5G and 1W for WiFi
* '''Frequency range''': WiFi – 2400-2500MHz, 3G/LTE – 698-960/1710-2170/2500-2700MHz (depending on bands being used)

There are more parameters to consider when choosing antennas also:
There are more parameters to consider when choosing antennas also:
* '''VSWR (voltage standing wave ratio)''' is a function of the reflection coefficient Γ, that describes power reflected from the antenna. The smaller the VSWR is, the more power is delivered to antenna. Minimum VSWR is 1, that means that no power is reflected from the antenna (ideal case). We recommend use WiFi antennas with VSWR≤1.5 and 3G/LTE with VSWR≤2.5.

We recommend use WiFi antennas with VSWR≤1.5, 3G/LTE with VSWR≤2.5 and 5G with <3.
* '''Cable (insertion) losses''' must be taken into account when using antennas with long cables. It is a measure of the amount of energy that is absorbed by transmission line (cable) as signal travels down and it is measured in decibels (dB). In general, a smaller diameter cable has more loss than larger diameter cable. For a specific cable type (different cable types have different losses), the longer the cable length the greater the amount of energy it absorbs. Also, losses depend on frequency – the higher the frequency the greater the loss.
