  • Page 28: Antenna Considerations

    avionics 4. Installation Overview 4.4 Antenna Considerations Good antenna placement and installation is important. FLARM signals are transmitted with very low power. Therefore, a good antenna installation is critical for equipment performance. Also the 1090 MHz and GPS antennas do have to be installed following certain requirements. If antennas are not installed in an optimum position, range and coverage are limited.
  • Page 29 avionics 4. Installation Overview One cockpit antenna comes included with delivery. Using a second FLARM antenna may provide better results as the reception coverage would be increased. The following locations have proven to be good places for installation of cockpit antennas. Other places may be suitable as well.
  • Page 30 avionics 4. Installation Overview Figure 4.2.: Cockpit antenna reception/radiation pattern FLARM External Antennas In aircraft that are mostly made of conductive materials such as metal or carbon ber, we recommend the installation of at least one external antenna for FLARM. Normally, such an external antenna would be placed underneath the fuselage of the aircraft.
