When installing antennas via extension cords rather than directly connecting them to the router, it is crucial to main-
tain a minimum distance of 7 cm between the two components. The maximum recommended distance between them
should not exceed 25 cm.
For optimal performance, it is advised to use radio frequency accessories (such as antennas and cables) that are re-
commended by Teldat.
Teldat offers a variety of suitable accessories for different locations, including antennas specifically designed for out-
door installation, antennas suitable for ceiling installation, and extension cables, among others.
3.5.2.1 Placing the antenna
The performance of devices can be significantly influenced by the orientation and location of their antennas relative
to other wireless and radiation devices, such as communication devices and personal computers.
Antennas serve to transmit and receive radio signals, but their effectiveness is also impacted by various environ-
mental conditions, including the distance between the device and the base station, physical obstructions, and inter-
ferences caused by radio frequencies (RF).
To achieve optimal coverage, please adhere to the following guidelines:
• When selecting a location for your antenna, try to avoid any physical obstacles that may obstruct the wireless sig-
nal. These obstacles, such as walls or objects, can degrade the signal quality. It is recommended to place the an-
tenna above ground and facing the nearest base station.
• Take into consideration the density of materials surrounding the antenna. Keep it away from walls, metal screens,
mirrors, and any other materials that may interfere with the signal reception.
• Avoid placing the antenna near columns or other objects that may cast shadows and reduce the coverage area.
• Ensure that the antenna is not in close proximity to metal pipes used for heating, air-conditioning, and other similar
purposes.
• Please note that other wireless devices, such as telephones and microwaves, may cause temporary interference
with radio signal quality.
• It is not advisable to install antennas in close proximity to racks that contain communication devices, computers,
and similar equipment. To address this issue, we recommend using an extension cable to position the antenna out-
side of the rack.
The following recommendations apply to all wireless devices:
• Avoid touching or moving the antenna while the device is transmitting or receiving.
• Refrain from touching any equipment that contains radiation-emitting devices with antennas that are very close to
or in contact with any exposed part of the body, especially the face and eyes, when it is transmitting.
• Do not install the device in potentially explosive areas.
• Be aware that wireless devices may cause interference with other devices. Avoid using the device in areas where
medical equipment is installed.

3.5.3 Connecting the GPS antenna

The Teldat 5Ge-Rail is equipped with a QMA connector that allows for the connection of an active GPS antenna.
However, it should be noted that since the router lacks internal antennas, installing an active 3.3V external antenna
on the Teldat 5Ge-Rail is necessary to enhance the quality of the GPS signal.
