Google Patents US3866228A - Two frequency localizer guidance system Sub-assemblies for on site assembly of tower sectionsĪntenna brackets that allow adjustment of antennas both vertically and horizontallyĮxel poles and lattice masts can be applied to support localizer antennas, subject to the height and the size of the antennas.US3866228A - Two frequency localizer guidance system The tower is made of 5 m tall sections, with total height of 10 or 15 metres. Structures located within the graded portion of the runway strip not meeting the frangibility requirement, such as an existing non-frangible ILS glide path antenna, should be replaced by a frangible structure, if practicable, and relocated within the non-graded portion of the runway strip.Įxisting structures located within a distance of 300 m from the runway end not meeting the frangibility requirement, such as an existing non-frangible ILS localizer antenna array, should be replaced by a frangible structure or relocated beyond a distance of 300 m from the runway end.Įxel GP-tower follows the same lattice structure concept as the approach masts, but is made to cope with the demanding requirements of extremely high rigidity and frangibility.
