The RF1 connector is connected to the module’s MAIN connector and the RF2 connector to the AUX connector.
Installing these antennas in the Regesta PLC router is necessary to improve the quality of the signal received and
transmitted by the WWAN module (GPRS, UMTS, HSDPA, HSUPA, etc.).
Some WWAN radio technologies (like GPRS or UMTS) only need one antenna to work properly. Depending on the
WWAN module installed, the Regesta PLC may only incorporate an RF1 connector. Regardless of the configuration,
the antenna on RF1 must be always installed while installing the one on RF2 is optional.

Note
WWAN antennas have to be installed for high-quality performance. All devices in this range run WWAN
interfaces with access to the 2G network (GPRS/EDGE). To access the 3G network
(UMTS/HSDPA/HSUPA) or HSPA+) the device must have additional licenses installed.
When the RF1 and RF2 antennas are connected via extension cords instead of being directly connected to the
router, the minimum distance between them must be 7 cm. The maximum recommended distance between the two
antennas is 25 cm.
To achieve an optimum performance, the 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.
3.5.2.1 Placing the antenna
Antenna orientation, its location with respect to other wireless devices and radiation devices, such as communication
devices, personal computers, etc., can significantly influence device performance.
Antennas transmit and receive radio signals. Performance is also affected by environmental factors such as distance
between the device and the base station, physical obstacles and other interferences due to radio frequencies (RF).
For optimum coverage, carry out the following instructions:
• 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 those used for heating, 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,
