Abstract

1,047,811. Screening aerial masts. BELLING & LEE Ltd. March 13, 1964, No. 10623/64. Heading H4A. To avoid interference with the performance of an aerial (not shown), the mast on which the aerial is supported is surrounded in the region of the aerial by a structure consisting of stringers of rectangular cross-section 16, 17 and 18 electrically connected to stringers of angle cross-section 19, 20 and 21, the stringers being interconnected by a plurality of electrically conducting rungs 28. In the arrangement shown the angular stringer 19 is clamped to rectangular stringer 16 and is connected to rectangular stringer 17 by rungs 28; the rectangular stringer 17 being clamped to angular stringer 20 which is interconnected with rectangular stringer 18. The structure is secured to the aerial mast formed by struts 1, 2, 3 by channel-cross-section distance pieces 4, 5, 6 by bolting or welding. Additional strengthening stringers 30, 31 may be provided at the midpoints of the rungs.
