1. An antenna assembly comprising:
a steerable phased array antenna with omnidirectional sector and a GNSS antenna, the steerable phased array antenna with omnidirectional sector being formed by a truncated cone-shaped bottom reflector with a wide end and a smaller pointing end and a truncated cone-shaped top reflector with a wide end and a smaller pointing end arranged in a superposition facing each other with their respective pointing ends, the steerable phased array antenna with omnidirectional sector being arranged in a spacing between the said truncated cone-shaped bottom reflector and truncated cone-shaped top reflector, wherein
the truncated cone-shaped bottom reflector and truncated cone-shaped top reflector are reflective for signals of the omnidirectional steerable phased array antenna, and
the truncated cone-shaped top reflector is further transparent for GNSS signals for the GNSS antenna.
