The present disclosure relates to a wireless communication network node (1) comprising an antenna arrangement (2), a transmitter arrangement (3) that is arranged to transmit output signals, and a receiver arrangement (4) that is arranged to receive input signals. The antenna arrangement (2) comprises at least one balanced antenna element (5) and a balanced antenna connection (6) that in turn comprises a first antenna branch (7) and a second antenna branch (8). The node (1) further comprises a power divider (9) that is arranged to divide the output signal in a first branch (10) and a second branch (11). The first branch (10) is connected to the first antenna branch (7) via a first amplifier arrangement (12) and a first power distribution device (13). The second branch (11) is connected to the second antenna branch (8) via a phase inverting device (14), a second amplifier arrangement (15) and a second power distribution device (16). In this way, a balanced feed is obtained for the transmitter arrangement (3) at the balanced antenna connection (6).
