Yagi GSM Antennas
In case of locations with a low level of RF, you cannot use the full potential of 3G or HSPA+ networks. For
such cases, you must use Yagi antennas (high gain, directive) for the respective GSM / HSPA frequency
bands, instead of the usual stick antenna.
The high gain antenna must be installed in a place with good reception (on the roof of the building).
Figure 11-3: High Gain Yagi Antennas and Cables for GSM/HSPA.
Such directive antennas feature from 5 up to 14 elements, provide 10-12 dBi gain and come with a
connection cable that is 10-15 m long, to allow installation of the antenna on a mast or atop the building,
where it gets a better level of 3G signal.
The cable is a special one, large diameter, which assures low siggnal attenuation in spite of the additional
length.
Such Yagi GSM/3G antennas are available from manufacturer upon request.
