Sprint 341U USB Modem
| Signal Improvement Solutions (Cellular) |
| Sprint 341U USB 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 Sprint 341U USB 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: Your Sprint 341U USB Modem operates on these frequency bands: LTE Band 25, LTE Band 26, LTE Band 41. Determine what frequency bands your operator uses here, then click on the frequency band link to view the best rated 4G LTE antennas compatible with the frequency band that both your device and your cellular operator supports.
STEP 2: Determine the cable length you need from the outdoor antenna to the Sprint 341U USB 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: PIG341U (NOTE: Need this pigtail to connect this device to antenna cable. It is included in preconfigured kits.)
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.
