IP66 protection will be lost, and all corresponding guarantees will become null and void, if mounting brackets areremoved or tampered with. Upgrading from existing single units to double units is possible, but can only be car-ried out at Kathrein due to IP66 considerations.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 operatingconditions.Extraordinary operating conditions, such as heavy icing or exceptional dynamic stress (e.g. strain caused byoscillating support structures), may result in the breakage of a mast mounted device or even cause it to fall tothe ground.These facts must be considered during the site planning process.The Triple-band 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 safetyregulations.
The details given in our data sheets have to be followed carefully when installing the antennas, filters, combiners, amplifiers and accessories.
The limits for the coupling torque of RF connectors, recommended by the connector manufacturersmust be obeyed.Any previous datasheet issues have now become invalid.
