GPS ANTENNAS
Haigh-Farr GPS antennas are available at the L1 frequency or
at both the L1 and L2 combined in a single connector. Our GPS
antennas are designed for flat, cylindrical or conical shaped
mounting surfaces and represent the future in aerospace
engineering as GPS receiver technology leaps forward.
Hemispherical coverage is provided when a single element is
used and spherical coverage is provided when Haigh-Farr’s
Wraparound™ configuration is used.
Dual channel designs are available which contain both a GPS
and Telemetry antenna in a single package.
Haigh-Farr GPS antennas are conformal and may be mounted
flush or on the exterior of the vehicle.
For high aero-heating applications an ablative heat shield may
be added. The single element may be provided inside a thin
conformal radome for enhanced ruggedization.

DESIGN CAPABILITY
With over 30 years of design history, your antenna configuration/
performance requirements may already exist, or extrapolations
from similar Haigh-Farr designs may be possible with minimal
effort. If a design meeting your requirements does not exist,
Haigh-Farr has the experience and modeling capability to
customize a solution. Contact Haigh-Farr for a review of your
antenna requirements.

the vehicle serves as the ground plane for the antenna. The patterns
shown were measured on a typical smooth cylindrical ground plane.
