Separate antennas are used to optimize the wireless field for the application. In industrial applications, this supports a reliable wireless field.
Antennas with several connections (dual or MIMO antennas)
Antennas with two connections combine two individual antennas, at 90° to each other, in one antenna enclosure. With these antennas, two data streams can be transferred simultaneously thanks to the two different polarization levels. Depending on the alignment of the polarization levels, these antennas are referred to as dual-slant (rotated through +/-45°) or vertical-horizontal.
Antennas with three connections contain three individual emitters that can be combined in one enclosure, either on different polarization levels (0°, +/-45°) or at a suitable distance from each other. The MIMO antennas can transmit three data streams simultaneously using multiple path propagation.
Transmission of several data streams results in increased data throughput and simultaneously a more reliable data transfer.
Directional effect
The suitable antenna is selected first by means of the wireless field characteristic. A distinction is made between omni-directional antennas and directional antennas.
Omnidirectional antennas
Omni-directional antenna
With omni-directional antennas, the wireless field is emitted in every direction surrounding the antenna (horizontal opening angle: 360°), but it weakens as the distance increases. There is a concentration in the vertical direction which creates passive amplification of the wireless field. Many omni-directional antennas have extremely weak radiation directly below the antenna due to their type of construction. This property can be seen in the associated antenna diagram.
ANT795-4Mx
With these omni-directional antennas, the wireless field is concentrated at 2.4 GHz and 5 GHz in the vertical plane of the antenna. All antennas of this type have an opening angle of 30° in the vertical direction and an antenna gain of 4 dB. They are directly mounted on the R-SMA or N connector of the SCALANCE W enclosure.
For the use of SCALANCE W-700 in accordance with IEEE 802.11n:
ANT795-4MA, ANT795-4MC and ANT795-4MD
The ANT795-4MC and ANT 795-4MD antennas can be rotated around only one axis, they have N-Connect connectors and degree of protection IP65, and they are used with the SCALANCE W788 M12 Access Points and the SCALANCE W748 M12 Client Modules.
The ANT795-4MA antenna features an additional joint, an R-SMA connector, and degree of protection IP30. It is therefore optimally suitable for the SCALANCE W788 RJ45 Access Points and the SCALANCE W748 RJ45 Client Modules.

ANT795-4MR, ANT795-4MS
The ANT795-4MR antenna can only be rotated about one axis and, due to its IP65 degree of protection, it is mainly used for the SCALANCE W788 Access Points and the SCALANCE W744-1PRO, W746-1PRO and W747-1RR Client Modules. Two of these antennas are supplied with these access points or client modules.
The ANT795-4MS antenna features an additional joint and is therefore ideally suited to the SCALANCE W784 Access Points and the SCALANCE W744-1, W746-1 and W747-1 Client Modules.
ANT792-6MN, ANT793-6MN
With these omni-directional antennas, the wireless field is concentrated at 2.4 GHz (ANT792-6MN) and 5 GHz (ANT793-6MN) in the vertical plane of the antenna. The antennas have a gain of 6 dB and 5 dB respectively.
N-Connect is used as the connector and can be connected to SCALANCE W over an extension cable from the range of IWLAN cabling. Both antennas are supplied with a mounting aid (metal bracket) that supports wall or mast mounting. The antennas are therefore ideally suited, for example, to providing wireless coverage for a place that has a mast at its center on which they can be mounted.
ANT795-6MN, antenna mounting tool for ANT795-6MN
With this omni-directional antenna, the wireless field is concentrated at 2.4 GHz and 5 GHz in the vertical plane of the antenna. The antenna has a gain of 6 dB and 8 dB respectively.

The antenna characteristic is such that good transmission properties also exist directly above and below the antenna. It is designed for mounting on a control cabinet or roof, but it can also be mounted under a roof, so it is suitable, for example, for the mobile units of an automated guided vehicle system. If it needs to be installed on a ceiling under a roof, the optional antenna mounting tool for ANT795-6MN is used.
ANT795-6MT
This antenna is an omnidirectional MIMO antenna with three QMA connections. The wireless field is concentrated at 2.4 GHz and 5 GHz in the vertical plane of the antenna. The antenna has a gain of 6 dB.
