    • An antenna arrangement comprising at least two antenna arrays (M, M', M'), each array comprising a plurality (N) of radiating elements (R) being arranged so as to have at least a plurality of corresponding radiating element positions, wherein for each radiating element there is associated an excitation means (E) comprising a magnitude weight (A) and a delay weight (α), wherein there is a first set (SE) of excitation means (E) associated with a first array (M) providing a first radiation pattern and a second set (SE') of excitation means (E) associated with a second array (M') providing a second radiation pattern. At least two respective excitation means (E) associated with a corresponding radiating element position of at least two respective arrays (M, M', M') have at least two different magnitude weights (An, A'n, A'n), and at least two respective excitation means (E) associated with a corresponding radiating element position of at least two respective arrays (M, M', M') have at least two different delay weights (αn, α'n, α'n). The excitation weights (An, A'n, A'n; αn, α'n, α'n) of the at least first and second sets of excitation means (SE, SE') are selected so that the main beam directions of the at least two antenna arrays essentially coincide and so that at least the magnitude of the correlation coefficient (p) associated with respective signals (S, S') communicated over the at least first and second array (M, M', M') is below 0.7 in a given side-lobe region, or so that the radiation amplitude patterns (P, P') associated with the at least first and second set of excitation means have an envelope with a substantial null-fill difference in a given side-lobe region with regard to the main beam peak.

    • The present invention relates to a wireless communication arrangement comprising a node and a leaky cable running between a first and second converter arrangement. The first converter arrangement connects a first downlink signal and a second downlink signal to the cable, and converts the second downlink signal from a first frequency to a second frequency. The cable's other end is connected to the second converter arrangement which converts the second downlink signal from the second frequency to the first frequency. The second converter arrangement also converts a first uplink signal from a third frequency to a fourth frequency. The first converter arrangement receives the converted first uplink signal from the second converter arrangement and converts it from the fourth frequency to the third frequency. The first frequency is separated from the second frequency, and the third frequency is separated from the fourth frequency.
