External Non-structural Installation
Figure 6-30 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 Alu 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 installation
of the (Section 6.6.1) antenna is used, with the antenna support bracket as the mounting surface. Follow
the applicable gasketing and sealant instructions in Section 6.4.2 (Teardrop style) or Section 6.5.2
(ARINC 743 style).
