¶ General Description
The Echo 19 is Siretta’s smallest embedded active GPS antenna, optimised for applications where space is at a premium. Measuring just 10 × 10 × 6.7 mm, it integrates a ceramic patch antenna with an onboard low noise amplifier to deliver strong GPS L1 reception despite its miniature size.With an RHCP gain of 17 dBiC and consistent top-hemisphere coverage, the Echo 19 provides robust satellite tracking and reliable performance. Its very low current consumption of ≤ 11 mA makes it an excellent choice for compact, battery-powered and mobile applications where efficiency and performance must coexist.
Supplied as standard with 100 mm of coax cable terminated with a U.FL/I-PEX connector. Alternative cable lengths and connector types can be fitted for volume orders.

¶ RF Spherical
The following graphs display the Average and Peak RHCP Gain across the entire spherical coverage of the antenna. These metrics provide a comprehensive view of the antenna’s ability to receive signals from satellites at all elevations and directions.
Consistently high gain across the sphere ensures strong and stable GNSS reception in a variety of operating conditions.
