Abstract

807,346. Aerials. TELERECTION Ltd. July 8, 1957 [April 7, 1956], No. 10687/56. Class 40 (7). An aerial for use at high frequencies consists of dipoles 7 connected together by means of adjustable delta matching sections 10, Fig. 1, which are connected by universal joints to a junction box 11. The free ends of the delta sections are slidably mounted on the dipoles and thus the matching to the feeder, connected to the junction box, can be correctly adjusted. The junction box takes up such position as the adjustment of the delta sections require. Directors and a reflector may be added as shown. The dipole need not be insulated from the supporting bars owing to the use of the delta sections.
