StratuxStratux antennas
Which antenna is which
| Antenna | Receives | Notes |
|---|---|---|
| 978 MHz | UAT: FIS-B weather and UAT traffic | US and Canada only |
| 1090 MHz | 1090ES traffic | Works worldwide, on the ground and in the air |
| 868 MHz | FLARM / OGN (Europe builds) | Needs the extra 868 MHz radio; see Stratux in Europe |
Compact (3 dBi) and large (5 dBi) antennas are both available on the parts page. Larger antennas can help in cockpits with poor reception.
Hand-tighten only
Never use pliers on the antennas. Over-tightening can break the small internal cables (pigtails) that connect the antenna ports to the radios. Finger-tight is enough.
Loose antenna port
If a port spins or wobbles:
- Power off and open the case.
- Hold the nut on the inside of the case.
- Tighten the nut on the outside with the included wrench.
- Check the internal cable isn't twisted before closing the case.
Broken internal cable
The 978 MHz UAT radio connects through a small u.FL cable that can break if the antenna is forced. A replacement u.FL-to-SMA pigtail is an inexpensive, common repair.
Placement
Keep the antennas vertical and away from large metal surfaces where you can, and give Stratux a view of the sky for GPS. Remember that on the ground, weather is often out of range no matter how good your antennas are.
