Sarantel SL1200 (GeoHelix-P2) Passive GPS Antenna offers unbeatable performance in the industry’s smallest package.
The SL 1200 (GeoHelix-P2) was designed from the ground up to be embeddable, delivers stable performance in all modes of use, whether it’s measured in free-space or surrounded by lossy dielectric materials.
Ideal uses for the SL1200 (Geohelix-P2) GPS Antenna include PDAs/PNDs, smartphones, GPS/Bluetooth® navigation devices - any device where the GPS antenna is to be embedded with other RF or high frequency electronics or where the device is to be held or worn by the user.
SL1200 (Geohelix-P2) 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 Up to 44dB filtering of common cellular frequencies Constrained near-field does not interact with nearby components or the user Strong circular polarization Stable impedance Broad beamwidth Easy to embed - predictable performance RoHS compliant |
