1.4 - Antenna Installation
Three types of antenna with several diameters are available for SAGEM LINK F radios.
• Integrated antenna with Sagem Link F ODU interface (0.3m, 0.6m, 0.9m, 1.2m or 1.8m
diameter). With these antennas, the ODU is directly attached on the antenna. In some protected
configuration using a coupler, the coupler is attached to the antenna, and the ODU are attached
on the coupler.
• External antenna with standard rectangular waveguide flange, which is connected to the
SAGEM LINK F ODU with a flex guide.
• External antenna with two access (dual polarized antenna) connected by two flex guides to the
ODUs.
Antennas models depend on the frequency bands :
• 7 GHz → 7.1 - 7.7 GHz
• 8 GHz → 8.025 - 8.5 GHz
• 13 GHz → 12.75 - 13.25 GHz
