Many clients use our measuring devices TMate Field and TMate WMR in order to identify the ideal positioning of antennas during installation. From our experience with various development and roll-out projects, nonetheless, additional challenges often arise, which should definitely be instructed:

  • Antennas are delicate structures. Often times, antenna cables only have a reduced tension relief, so tension should not be applied to the antenna cables that have already been installed.
  • The screw-nuts around antennas in meter cabinets or on the brackets should be tightened with a maximum torque as specified by the manufacturer (often times approx. 3-5 Nm). Otherwise, the antenna may be damaged, with outdoor antennas often showing damage at the level of seals.
  • SMA (and other screw connections) should be tightened with a torque wrench. If the connections are done by hand, then these should only be slightly hand-tightened.
  • All antenna connectors must be protected with dummy plugs when installed (especially when moving the antennas into meter cabinets).
  • Antenna cables must not be bluntly bent during installation. Otherwise, there is a significant risk of performance loss and subsequent errors.
  • If the antenna cables are damaged (e.g. cracks in the sheath), the entire antenna should be changed. At the damaged antenna, the antenna cable should be immediately cut. The defect should be marked with a piece of insulating tape or something similar, for later analysis.

In practice, often times other challenges are making their presence known. Upon request, we are more than happy to provide trainings on all topics related to the installation of antennas. Thanks to the efficient training of technicians with regard to the roll-out of Smart Meter Gateways and other devices with mobile communications (GSM / UMTS / LTE) and other mobile standards (Wireless MBus, LoRo, BLE, WLAN), you can save hard cash.
