• 1. Attach the 4 suction cups to the back of the antenna mounting bracket by inserting the rubber tip of each suction cup through each slot and locking them into place.
  2. Using the provided wrench, connect the antenna cables to the base of the T-Mobile 5G Gateway (G4AR or G4SE), matching the numbers on the corresponding ports and cables (be careful not to tighten the cables too much, as the connector could get damaged).
  3. Place the antenna on desired window, ideally on an upper floor, by pressing firmly on the suction cups (for best results, make sure the window surface is clean before mounting).
  4. On the T-Mobile 5G Gateway, navigate to the Antennascreen and switch from Internal Antennato External Antenna(if you disconnect the antenna from the gateway, you will need to change this setting back to Internal Antenna).

• If the gateway loses signal when the antenna is attached:

  1. The T-Mobile 5G Antenna is only compatible with the T-Mobile 5G Gateway (G4AR or G4SE). Make sure you are only connecting the antenna to a compatible gateway.
  2. Make sure the cables are fully screwed into the correct ports. (hand tighten to prevent over tightening.)
  3. Change the antenna settings on the gateway LCD from Internal Antenna to External Antenna (if you have unplugged the External Antenna, you will need to change this setting back to Internal Antenna)
  4. Check placement of the antenna. The antenna is for indoor use only and the back of the antenna (where the window mount bracket is) should face the nearest tower.
  5. If the gateway loses signal or the signal degrades while the antenna is attached and the steps above have been completed, exchange the antenna.
