When the antenna is mounted on GSM device, it can be angled to have either a 45 or 90 degree slope. The joint is placed immediately after the connector.
If the transmitter is in a metal box, with the antenna inside, there will be no signal. In such situations, it is recommended to use an antenna with wire that can be placed outside the box.
NOTE: We recommend that you use our 7 dBi antenna, if it is to be used in an installation where there is poor signal. Often seen in holiday areas.
