A shielding grounded enclosure receives containers holding articles with UHF RFID tags with codes to be read out in a multi-read operation. The container can be a cart or bag trolley carrying garments, linens, cleaning items, floor mats other RFID coded items. The enclosure forms a tunnel leading into a reading zone where antennas are mounted in the back of niches, such as the back of a transverse channel extending up the sidewalls and over the top of the tunnel. The antenna arrangement is such that illumination/polling signals are applied strongly in the reading zone. The depth of the niches and the length of hallways or foyers leading into the reading zone are dimensioned to minimize or eliminate lines of sight from the antenna to the area outside of the enclosure. Additionally or alternatively, shielding enclosure such as a conductive door is movable across an opening leading into the reading zone.
