ANTENNA GASKET KITS DAYTON-GRANGER ANTENNAS aviall.com North America and AOG 1.800.AVIALL.1 International Sales 1.800.AVIALL.3 or +1 972.586.1985 1229 North America and AOG 1.800.AVIALL.1 International Sales 1.800.AVIALL.3 or +1 972.586.1985 ULTRA SEAL conductive antenna gasket kits. Dayton Granger's new conductive antenna ULTRA SEAL gasket is a 2 ounce kit that is loaded with 3000 miniature aluminum balls. The 2 ounce kit can cover a 40 square inch area. The process of applying the ULTRA SEAL gasket is simple. First spread the aluminum ball elastomeric material over the antenna baseplate, then mount the antenna to the aircraft. The 3000 aluminum balls bridge the gap between the aluminum antenna baseplate and the aluminum aircraft skin. Since the balls are manufactured from the same aluminum alloy as the aircraft skin and the baseplate of the antenna, corrosion due to dissimilar metals is eliminated. The ULTRA SEAL also seals the interface from water entry and forms a fillet around the circumference of the antenna base. The low peel strength of the elastomeric allows easy removal of the antenna without the use of mold releases or release agents. NSN: 5999-01-446-1622 This technique allows the stocking of one type kit to meet all antenna mounting gasket requirements and provides a superior long life RF interface, free from corrosion. Our ULTRA SEAL gasket kit can be used to install any antenna, thereby eliminating the need to order and stock hundreds of specific gaskets for various antenna baseplate sizes. Our technique offers superior RF electrical continuity between the antenna base and aircraft structure. Our approach is less expensive than competitive conductive gaskets now on the market. Our ULTRA SEAL gasket has a low peel strength which permits the antenna to be removed relatively easily, since the ULTRA SEAL gasket does not adhere with very much strength to the antenna base or the aircraft structure. Our approach uses an aluminum alloy that is the same as the aluminum alloy of the aircraft and baseplate of the antenna and thus corrosion of this interface (which has historically been a major problem) is eliminated. There are no dissimilar metals in our technique. Our ULTRA SEAL gasket offers a barrier which prevents water from entering into the joint between the antenna and aircraft structure. A separate sealant need not be applied around the circumference of the antenna to seal it against water entry. This gasket since it is corrosion free, will have an extremely long, trouble free life.
