The 1001011 SMT antenna is designed with Ethertronics' patented IMD™ technology to address all GPS needs requiring a high performance embedded antenna solution. The linear polarization of the 1001011 provides a strong omnidirectional signal, making it well suited for uncontrolled environments. The 1001011 offers strong resistance to detuning, more than 55% efficiency in-band, and a VSWR reaching 1.14:1, with only 4 mm of ground clearance. When placed on a metal surface, Ethertronics’ 1001011 antenna still provides more than 25% efficiency with a VSWR reaching 2:1.
