1090 MHz Cockpit Antennas
In most cases, the cockpit antennas included with delivery are sufficient for good operation.
Although not being as critical as FLARM antennas, make sure the requirements below are
met for optimum performance.
1. Always install 1090 MHz antennas vertically.
2. Ensure that the antenna cable is routed away from the antenna in an orthogonal way
in the first 15 cm (6 inches) or use angled antenna connectors (for external antennas).
3. Do not coil the antenna cable.
4. Ensure that no conductive parts (metal, carbon fiber) are close to the antenna.
5. Install the antenna in a location where it has a clear view and is not obstructed from
nearby structural parts.
Always install dipole antennas vertically
Ensure that the antenna cable is routed away from the antenna in an orthogonal way.
