Antenna Placement
- ELT antenna installation is governed by 14 CFR § 91.207 and AC 91-44A: It asks for:
- "Proper installation" (which means you need to follow the installation instruction from the ELT manufacturer)
- "The presence of a sufficient signal radiated from its antenna" (annual test).
- The antenna to be vertically mounted
- You may install the antenna inside the airplane if
- The airplane skin is non conductive (the RV-10 fiberglass canopy area should be fine) or the antenna is centered behind a window of at least 12 x 12 inch size
- You provide a ground plane for it (24 inches radius for 121 MHz!)
