The WATTS MODEL GP-5A DIRECTIONAL IMAGE GLIDE PATH ANTENNA provides smaller critical areas for Category I/II/III Instrument Landing Systems. Watts has recognized that worldwide engineering practices employed to overcome difficult site problems with image glide path (GP) antenna systems indicate that the antenna lateral radiation pattern is being substantially challenged in the modern airport environment. Introduction of larger aircraft such as the Airbus A380 and airport efficiency constraints are also driving a reduction in the size of the critical area of the Glide Path system in order to take advantage of the larger jets and to increase airport capacity.
The Model GP-5A Antenna element, nomenclature GP-5A, has been designed and manufactured by Watts Antenna Company to provide highly accurate guidance information to an approaching aircraft while permitting increased flow of aircraft traffic in the vicinity of the GP tower. The development was undertaken by the manufacturer starting in the fourth quarter of 2003.
Directive, narrow beam produces optimum pattern in airport multipath environments.
Asymmetric radiation pattern provides greater use of all taxiways in the vicinity of the GP mast.
Rejects sources of both static and dynamic multipath on the side of the runway containing the tower.
No shim adjustment necessary.
