| Teltonika TRM250 LTE Modem includes an antenna port to attach external cellular antennas. See below for different options for high gain and high performance indoor and outdoor antennas to improve the signal strength and indoor coverage. Additionally, see below for RF bidirectional amplifiers/ distributed antenna systems/ repeaters/ small cells to further improve indoor coverage without directly attaching pigtail/ cable the device. |

Because the Teltonika TRM250 LTE Modem device has an external antenna port you could use the high gain external antenna kits above to boost your signal. However, if your outdoor signal is very weak, or you require a very long cable run to get from the outdoor antenna to the device (long runs lead to large signal loss) consider using an RF bidirectional amplifier/ repeater suitable for the supported bands and cellular operator to boost your indoor coverage: LTE Antenna Boosters/ RF Bidirectional Amplifiers/ Repeaters/ Relays |

STEP 1: Determine what frequency bands your operator uses here, then click on the frequency band link to view the best ranked cellular antennas compatible with the frequency band that both your device and your cellular operator supports. Your Teltonika TRM250 LTE Modem operates on these frequency bands: Cellular, LTE Band 1, LTE Band 2, LTE Band 3, LTE Band 4, LTE Band 5, LTE Band 8, LTE Band 12, LTE Band 13, LTE Band 18, LTE Band 19, LTE Band 20, LTE Band 28, LTE Band 39, 900 MHz.
STEP 2: Determine the cable length you need from the outdoor antenna to the Teltonika TRM250 LTE Modem and configure your length here (select N-Male on both ends)
STEP 3: Determine if you need a lightning protection device. If you do, you will need a jumper cable.
STEP 4: Order the pigtail for your modem below:
STEP 5: If the pigtail's Connector 2 is FME-F you will need an N-Female/FME-F adapter to mate to the N-Male cable in step 2. Alternatively, select an N-Male/FME-M cable in step 2 above (more expensive and less re-usable) to avoid requiring this adapter.
