The present invention relates to radio communications subscriber apparatus and, in particular, although not exclusively, to the installation of equipment for new subscribers to a telecommunications network comprising a fixed wireless access system. An antenna arrangement is disclosed for providing communication links in a fixed wireless access system, the antenna including receiver means including a receive signal demodulator; wherein a signal processing unit receives signals from the received signal demodulator which signal processing unit includes indicators relating to a received signal. The indicators are operable to indicate signal level and some form of signal quality measure e.g. signal vector error, signal to interference or timing stability. In the alignment phase the processor analyses the received level and quality while the antenna arrangement is scanned across the signal direction (towards the base station in a FWA system). From the stored scan data the processor identifies the best data set and sets an acceptance window. When the antenna arrangement is rescanned the processor identifies when the received signal conditions are within the window. From such an indication the antenna can be secured in a preferred orientation. The invention is applicable to subscriber self-installation.
