➊
TECHNICAL PERFORMANCE
•
Excellent phase center and group delay stability
•
Highly stable radiation pattern (magnitude & phase)
•
Optimized radiating element combined to a choke
ring provides excellent multi-path immunity
•
Wide operational bandwidth of the cross dipoles
•
Reduced ohmic losses (< 1.0 dB)
➋
DESIGN

Sealed radome to be used in severe environments
•
Dedicated fi lters for out-of-band rejection and
dedicated LNA for pre-amplifi cation
•
Reduced accommodation (easy to install on the
top of a mast)

This antenna has been designed under
the SWIRLS contract with the Galileo
Supervisory Authority (GSA) specifi cally
targeting reference applications
with a high level of fl exibility
in terms of covered frequency bands.
