These pocket sized readers have their antenna located at the end of either a 60cm or 100 cm long pole. The antenna is either a small focal one in the tip of the pole or a 100mm diameter circular antenna. The pole can be straight or incorporate a 45 degree bend. The readers are powered by a simple 9 Volt alkaline battery with last number recall.
Please note that these readers cannot operate independently without the pole extension antennas.
