Antennas
| Garmin GPS antenna for G3X | GA56 (BNC connector) (not included with G3X) "kit" contains doubler plate |
| Garmin GPS antenna for certified GPSs (GTN650, GNX,...) | GA35 (TNC screw-on connector) (GPS price might include antenna or not, check with vendor, Sarasota includes it) |
| Transponder / ADS-B antenna | Comant CI-E05 (experimental version of CI-105)
|
| VHF top antenna
(works better for ground communications) |
Comant CI-E21 (experimental version of CI-121)
|
| VHF bottom antenna
(works well when airborne but not necessarily on ground) |
Comant CI-E22 (experimental version of CI-122)
|
| MB antenna | Rami AV-64 |
| VOR/GS antenna | Archer VOR ANT LT Model 1 (different order number for left and right, please check) |
| ELT antenna | (whatever comes with your ELT) |
Example of Bob Archer NAV / Glideslope Antenna mounted in aftermarket Aveo ZipTip.
Frequency plot of Bob Archer antenna (shows 50 Ohm and resonance in the VOR/LOC frequency range of 108-118 MHz):
ELT 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!)
