AJAX Antenna for LTE or radio communication, Standard SMA connector, Wired communication up to 3 m, Installation using double-sided tape

Functional elements

1. Antenna.
   Coaxial cable.
   SMA connector (male).

   Compatible hubs

   A compatible Ajax hub is required for the antenna to work.

   The device is compatible with:

   • Hub BP Jeweller

   ExternalAntenna sold separately.

   Operating principle

   ExternalAntenna improves communication between the hub and connected devices or mobile network. It is useful when the Hub is installed in a safe, in a reinforced concrete room or in other places where the signal has to overcome obstacles. The antenna can be connected to the required Jeweller, Wings or Cellular connectors.

   Choosing the installation location

   When selecting the installation location for the antenna, factors affecting its performance must be taken into account:

   • Signal strength of the selected communication channel (Jeweller, Wings or Cellular).

   • Distance between the antenna and the hub. When using two or more antennas, the distance between them must be at least 60 cm.

   • Obstacles affecting the radio signal: walls, ceilings and large objects in the room.

Follow the installation recommendations when designing your Ajax system. The safety system must only be designed and installed by specialists. A list of recommended Ajax partners is available here.

Places where the antenna should not be installed

• In rooms where the temperature and humidity exceed the permissible limits. This can damage the antenna.

• In areas with low signal levels. This may cause loss of connection.

• Close to metal objects and mirrors. Conductive objects may obscure the antenna.

Preparing for installation

Before installing the external antenna, make sure that:

• The hub is compatible with the ExternalAntenna;

• the hub has a stable 2-3 bar signal with the mobile network at the installation site;

• all connected devices have a stable 2-3 bar signal at the installation site;

• the cable length from the hub to the installation site is sufficient.

Cable layout

When preparing the cable routing, check the wiring and fire safety regulations for your region. Strictly comply with these standards and regulations. Practical advice on cable routing is available in this article.

Cable routing

Before installation, read carefully the section Selecting the installation site. Avoid deviations from the system design. Failure to follow the basic rules and recommendations in this manual may cause malfunctions.
