TT&C ANTENNAS

S-Band TT&C
Antenna
ANYWAVES S-Band antenna is our flagship antenna
with a strong flight heritage (TRL 9).
Perfectly suited to LEO platforms, this antenna
operates both in transmission for telemetry and in
reception for telecommand.

Its wide beam coverage enables the best satellite


availability for TT&C link. In pair work, ANYWAVES
S-band TT&C antenna provides an omni-directional
coverage to enhance the satellite availability.
This antenna is provided with right or left-hand
circular polarization with a SMA (SubMiniature version
A) connector.

NB: compatible with ANYWAVES Test Cap for S-Band
