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 (Spruce part no 11-21015-1, but 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. Note how the outer edge of the hinge overlaps to the center line of the attachment plate.
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!)
