If the RF1 and RF2 antennas are connected via extension cables rather than being screwed into the router, the min-
imum distance between them must be 7 cm. The maximum recommended distance between the two antennas is 25
cm. In order to comply with EMC regulations, the extension cable must not be longer than 3 m.
To achieve optimum performance, any radio frequency accessories installed (antennas and cables) should be those
recommended by Teldat.
Teldat offers a series of accessories (90º mount antennas, antennas for outdoor installation, antennas for ceiling in-
stallation, extension cables, etc.) that allow you to install the devices in different locations.
4.2.4.1 Placing the Antenna
Antenna orientation and its location with respect to other wireless devices and radiation devices (such as communic-
ation devices, personal computers, etc.) can significantly influence device performance.
Antennas transmit and receive radio signals. Performance is also affected by environmental factors (such as dis-
tance between the device and the base station), physical obstacles and other interferences caused by radio frequen-
cies (RF).
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.
• 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 canals, 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.
The following recommendations are applicable to all wireless devices:
• Do not touch or move the antenna while the device is transmitting or receiving.
• Do not touch any equipment containing devices that radiate, where the antenna is very close to or touching any ex-
posed part of the body (particularly the face and eyes), when it is transmitting.
• Do not install the device in areas where the atmosphere is potentially explosive.
