The JDGA GeoHelix-P3 Active GPS Antenna was designed from the ground up to be embeddable and deliver more gain for less sensitive receivers..
Ideal uses for the Geohelix-P3 Active GPS Antenna are navigation devices requiring limited space. Can be integrated into handheld or body-worn devices
Geohelix-P3 Product Summary GPS L1-band quadrifilar helix antenna Integral balun Requires no ground plane High isolation from platform rejects common-mode noise Negligible proximity de-tuning No embedding sleeve required Constrained near-field does not interact with nearby components or the user Strong circular polarization Stable impedance Broad beam width Easy to embed - predictable performance RoHS compliant |
