Difficulty Locking onto Satellites

If you are having issues with your VBOX 3iS not locking onto satellites as expected, the checklist below covers the most typical solutions: 

Damage to the cable or the connector

The cable should be placed in a position that avoids tight angles being inflicted on the cable, as this can damage the thin core. The VB3iS should also be securely positioned to avoid strain on the point where the cable is attached to the connector during violent vehicle manoeuvres.

  1. Make sure that the antenna is placed in a position where it has an unobstructed view of the sky (see GNSS Antenna Placement for further details).
  2. Check the antenna connection with the VBOX 3iS.
    Even small amounts of dirt in the socket can cause a significant reduction in the signal strength.
  3. Check the cable at the plug and along its length for any damage.
  4. Check that the power supply is connected and free from damage.
  5. If possible try another known working antenna, to confirm the antenna's functionality.
  6. Perform a GNSS Coldstart and then leave the unit powered up in an open static position for at least 15 minutes.
