IWLAN antennas

Directional antennas

Directional antenna

With directional antennas, the radio field is emitted both in the

horizontal and vertical plane in the range of the opening angle.

It is concentrated in these areas and generates passive

amplification. Based on the opening angle, directional antennas

are divided into sector or wide-angle antennas (opening angle >

approx. 30°) and strongly directional antennas.

Directional antennas are ideally suited to wall or mast mounting.

The supplied mounting aid is used for a targeted adjustment.

N-Connect is generally used as connection plug. The antenna

can be connected to SCALANCE W over an antenna connection

cable from the IWLAN cabling systems range.

ANT795-6DC, ANT793-6DG and ANT793-6DT

The radio field can be aligned at 2.4 GHz and 5 GHz using these

sector antennas. Each has an antenna gain of 9 dBi.

Thanks to their characteristics, they are suitable, for example, for

providing wireless coverage for an area in front of a wall.

The ANT795-6DC antenna is suitable for both frequency bands

2.4 and 5 GHz. It has an N-Connect connection. Together with a

SCALANCE W780 or W770, two or three antennas of this type

can also be used for covering multiple sectors.

ANT793-6DG is a dual-slant antenna with two N-Connect con-

nections for the 5 GHz frequency band.

ANT793-6DT is a MIMO antenna with three QMA connections for

the 5 GHz band.

The ANT795-6DT is connected to the SCALANCE W-780/W740

Access Points via QMA/N-Connect male/female IWLAN adapter

cables and the IWLAN flexible antenna connection cables in the

relevant length and connector version.

ANT792-8DN, ANT793-8DP, ANT 793-8DJ and ANT793-8DK

These strongly directional antennas enable genuine amplifica-

tion of the radio field. The radio field is concentrated in a narrow

cone due to the narrow opening angle. High passive gains and

long ranges are therefore achieved.

Due to the high passive gain, the antennas are ideally suited to

bridging large distances.

The ANT792-8DN antenna is suitable for the 2.4 GHz frequency

band and has an antenna gain of 14 dBi.

ANT793-8DP is an antenna with a high gain (13.5 dBi) in a

compact enclosure. It is suitable for the frequency band from 4.9

to 5.35 GHz and therefore preferably for applications in Japan.

ANT793-8DJ (18 dBi) and ANT793-8DK (23 dBi) are strongly

directional antennas with vertical-horizontal polarization. They

each have two N-Connect connections.
