@yhcho61 If you're asking where to plug in the antennas to the Voxl-Cam, then most times the Voxl-Cam has extensions from which to attach the LTE antennas to. If it didn't, you would just need to take the backpack off and thread the antenna through the slot of the backpack and plug them in to the modem. Reattach the backpack and then initialize the modem to use it.
