Antenna And Doubler Installation - GOODRICH Stormscope Series II Installation Manual

2.5 ANTENNA AND DOUBLER INSTALLATION

Figure 2-3 shows the mounting holes and dimensions for the antenna and doubler plate.
1. Use the antenna doubler plate as a template to mark hole locations on the aircraft skin.
Ensure that the location selected allows adequate space inside the fuselage
for the doubler plate to clear ribs and aircraft structure. (It may be
necessary to cut the doubler plate to ensure proper fit.)
2. Attach the doubler plate to the inside of the fuselage as shown in figure 2-4.
3. Mount the antenna to the aircraft as shown in figure 2-4.
1. Do not paint the antenna. It has been coated with a special conductive paint to
inhibit the build-up of precipitation-static.
2. Do not over-tighten the antenna mounting screws during installation on convex
surfaces. Doing so may cause stress cracks and shorten the life of the antenna.
3. To ensure a good electrical ground connection (metal-to-metal contact) remove the
paint from the aircraft skin under the double plate mounting screws and prepare the
surface with Alodine® No. 1001. Failure to provide a good ground connection may
affect system performance.
