    摘要: An arrangement for coupling external antennas (14, 15) to a communication unit (20) comprises, for example, a first filter (25) located in the unit, which filter combines at least signals of a first frequency range and signals of at least a second frequency range to be transmitted and feeds them via a common coupling (29, 26) to external antennas (14, 15), filters the received first signals to a first radio part (11) of the unit (20), and filters the received second signals to a second radio part (12) of the unit (20), and a second filter (16) in the antennas, for example, which filter combines at least the first signals and at least the second signals received and feeds them via the common coupling means (29, 26) to the unit (20), filters the first signals to the transmitted to first external antenna (14), and filters the second signals to be transmitted to a second external antenna (15).
