Figure 12-36. Example Teardrop Footprint Antenna Mounting Under Fabric Skin
Figure 12-37 is an example of an external, non-structural mounting of the antenna in a tube-and-fabric
aircraft. The antenna support bracket shown should be made of 2024-T3 Aluminum with a minimum
material thickness 0.032" and maximum distance between airframe tubes of 36". The bracket is installed
to the airframe under the fabric, and the antenna is mounted externally to the bracket. The generic
installations of the teardrop footprint (Figure 12-30 and Figure 12-31) and ARINC 743 footprint
(Figure 12-32) antennas are used, with the antenna support bracket as the mounting surface.
