Equipment and materials

Two discharger units eliminate static interference problems in aircraft NAV‐COM systems and ensure clear in‐flight communication. Suitable for both private and commercial prop‐jet or propeller aircraft, they have close packed highly sensitive tungsten filaments, which continuously divide discharging energy into silent pulses, form the tip of the discharger unit. An outer Teflon cover, which will not crack or peel, protects the conductive core from exposure to corrosive fluids and atmospheric erosion and the unit‐which has a lightweight rigid fibreglass core support‐is virtually unbreakable. There are trailing edge and a wing tip type discharger which can be fixed quickly into existing mounting holes with the strong nickel coated aluminium bracket supplied.
