Antenna Port Location

The 250U has 2 antenna ports, one for a 4G antenna and one for a 3G antenna. Make sure to connect the antenna to the port for which you are trying to boost signal - the 3G port is closest to the Sprint/CLEAR logo (AWAY from the LED lights); the 4G port is closest to the LED lights.

Tips For Using Your Antenna/Adapter Cable:

  • Be GENTLE when connecting or disconnecting the adapter cable to/from your modem - the connector pins and the ports themselves can be VERY FRAGILE!!!
  • Boosting 4G signal requires a 4G-capable antenna. Not all antennas will boost 4G!
  • If the adapter cable feels loose when you connect it to the antenna port, remove it and roll it between your thumb and forefinger while applying medium pressure. The friction and pressure will cause the connectors' "teeth" to tighten up, allowing it to fit more snugly in your device's antenna port.
  • If you're using a magnetic mount antenna, make sure it is connected to something magnetic or it will not work! If you're using an antenna that included radials, make sure the radials are screwed on or it will not be as effective! (other antennas do not require grounding)
Already have an antenna/amplifier and just need the adapter cable?
