• Designed for co-siting purposes
• Enables feeder sharing
• Integrated auto-sense technology for automatic DC / AISG detection andbypass functionality.
Combine Mode (near BTS):DC/AISG auto-sense for port 1…3 and short circuit detection on port4. The first port (1, 2 or 3) which is supplied with a DC/AISG signal wilautomatically be by-passed to port 4
Split Mode (near antenna):Automatic DC/AISG by-pass from port 4 to port 1…3 if no short circuit is detected
A detailed manual about auto-Sense technology can be downloaded on our homepage.
• Suitable for indoor or outdoor applications
• Wall or mast mounting
• Available as a single unit, or for XPol antennas as a double unit
• Built-in lightning protection

Please Note:
The mounting plates can be removed by loosening the screws j to m (M5 x 12) and replaced with other means of mounting, always provided that the max. drilled depth of 7.5 mm is respected with the choice of replacement screws.
As a result of more stringent legal regulations and judgements regarding product liability, we are obliged to point out certain risks that may arise when products are used under extraordinary operating conditions.
Extraordinary operating conditions, such as heavy icing or exceptional dynamic stress (e.g. strain caused by oscillating support structures), may result in the breakage of a mast mounted device or even cause it to fall to the ground.
These facts must be considered during the site planning process.
The Combiners are designed to operate under the environmental conditions as described in ETS 300 019-1-4 class 4.1 E and have passed environmental tests as recommended in ETS 300 019-2-4.
The installation team must be properly qualified and also be familiar with the relevant national safety regulations.
The details given in our data sheets have to be followed carefully when installing the combiners and accessories.
The limits for the coupling torque of RF connectors, re- commended by the connector manufacturers must be obeyed.
Terminate unused inputs with a suitable 50-Ohm load, e.g. 78210484.
Any previous datasheet issues have now become invalid.
