GPS L1, SBAS L1, QZSS L1 ULTRALIGHT GPS HELIX ANTENNA

GPS L1, SBAS L1, QZSS L1 Ultralight GPS Helix Antenna

The ELT0240 antenna is a balanced design, providing galvanic isolation from the host device and effectively rejecting common-mode noise on the system ground. Its dielectric-loaded structure tightly confines the near-field region, making it highly tolerant to nearby materials — detuning effects are negligible, and the antenna maintains consistent radiation pattern and efficiency even under dielectric loading.
A high-performance integrated SAW filter attenuates unwanted signals from common GSM and ISM bands by up to 30 dB, often eliminating the need for additional external filtering.
While the ELT0240 can be used as an external stub-style antenna, its isolation characteristics also make it well-suited for embedded applications.
