Overview
Inventek’s GPS antenna, part number, ACTPAT182‐01‐IP is designed to work with a variety of GPS receivers. The
active antenna is designed to snap directly onto the Inventek GPS modules ISM300F1 and ISM300F2 Family of
GPS receivers.
The standard model is made from ceramic and comes with a LNA and mini coaxial 1.13mm cable with a U.FL RF
connector that you can mount it directly on the board or attach to your GPS receiver. The active antenna can be
used in a variety of applications including automotive with an impedance of 50 ohms.
The antenna, P/N ACTPAT182‐01‐IP lets you integrate low cost GPS functionality into your product quickly and
easily. It’s suitable for a wide range of applications, including the most compact:
•
•
•
•
•
Hand‐held personal positioning and navigation
External PDAs, Pocket PCs and other hand‐held computers
Fleet management
Asset tracking
Automatic vehicle location
The ACTPAT182‐01‐IP provides world class performance suits it to navigating urban canyons, as well as wide‐
open spaces. Being lead‐free, it complies with the European Union’s RoHS (Restriction of Hazardous Substances)
directive.
