GPS Antenna Module


Model: D-18

D-18

Compact & Sensitive GPS Antenna module with Extremely Low Attenuation & Power Consumption

Overview

Featuring excellent anti-signal interference capabilities and amazingly low current consumption, D-18 is the most compact GPS antenna module currently available on the market. Thanks to our cutting-edge technology that makes the device the tiniest possible without sacrificing performance. D-18’scomprehensive coverage can extend to far-off horizon, performing excellently in foliage or urban canyon environment – even in the presence of electromagnetic interference!

Coming up with diminutive but substantial enclosure plus unparalleled performance, D-18 is compatible with almost every GPS receiver model available on the market and provides a perfect alternative for a vast range of GPS applications in the fields of AVL, vehicle navigation, aviation and military.

FV-4H, Combining high sensitivity, exceptionally low power consumption and a USB port in a small module measuring just 17 x 22 mm FV-33, Built in with SIRFIII chipset, FV-33 features ultra high sensitivity and is compatible with 95% of GPS applications, such as navigation, vehicle and covert tracking applications
