A television receiving apparatus includes a tuner having an input port for image-representative signals, an input port for an external antenna, and an internal or associated external indoor antenna array including at least two electronically integrated antenna-WLNA elements. A processor includes a plurality of RF switches and at least one hybrid, for selectively generating a plurality of signals including sums and differences of signals from said elements. The sums and differences are compared with each other and with the external antenna signal to select the best signal, and that selected best signal is coupled to the input port of the tuner.
