Antenna usage
ANT4
4G (Diversity)
When the antennas are not directly connected to the device but installed through extension cords, the minimum dis-
tance between the two of them must be 7 cm. The maximum recommended distance between the two is 25 cm.
To achieve optimum performance, the radio frequency accessories installed (antennas and cables) should be those
recommended by Teldat.
Teldat has a series of accessories (90º mount antennas, antennas for exterior installation, antennas for ceiling install-
ation, extension cables, etc.) that allow you to install the devices in different locations.
3.5.2.1 Placing the antenna
The orientation of the antenna and its location with respect to other wireless devices and radiation sources (such as
communication devices, personal computers, etc.) can impact device performance.
Antennas transmit and receive radio signals. Environmental factors (such as the distance between the device and
the base station), physical obstacles and other RF interferences can impact their performance.
For optimum coverage, follow these steps:
• Whenever possible, place the antenna where there are no physical obstacles. Obstacles between the antenna and
the base station degrade the wireless signal. Place the antenna above ground level facing the nearest base sta-
tion.
• The density of materials also affects antennas. Place them away from any type of wall, metal screens, mirrors, etc.
• Do not place the antenna near columns, which may throw shadows and reduce the coverage area.
• Keep the antenna away from metal pipes (such as those used for plumbing, air-conditioning, etc.).
• Please bear in mind that other wireless devices (such as telephones, microwaves, etc.) can temporarily interfere
with the quality of the radio signal.
• We do not recommend installing antennas near, or between, racks containing communication devices, computers,
etc. Use an extension cable and place the device outside.
