Active outdoor antenna with integrated amplifier to receive digital, terrestrial TV signals (DVB-T). The weatherised and waterproof antenna can be installed on an exterior surface. Due to its mounting support it can be mounted in many different ways near a window (window ledge, window frame ), near balconies or already existing antenna masts, as well as directly on the house wall. To improve the reception quality, the mounting support additionally provides a frame joint for alignment. The antenna body can be detached remounted “turned down”. Thus, the symmetrical antenna shows no preferred position regarding its functionality nor regarding the way it can be mounted. In electrical respect the antenna is suitable for both horizontal and vertical polarisation, irrespective of the mounting position.
