Product Name : GeoHelix-P2(SL1203A Rugged Passive Antenna)

Description : GeoHelix-P2(SL1203A Rugged Passive Antenna)


Product Description

Built on patented PowerHelixR filtering antenna technology, the Ruggedised GeoHelix-P2 GPS antenna is the smallest quadrifilar helix antenna available, providing high performance in difficult GPS applications. The Ruggedised GeoHelix-P2 antenna is ideal in applications where:

‧ the device is handheld, body-worn, or otherwise surrounded by high-dielectric materials that would de-tune conventional antennas;
‧ the antenna is externally mounted and in close proximity to other antennas, e.g., on top of a two way radio or tactical radio close to transmitting antennas;
‧ there are tight constraints on the size of the device or the amount of space allocated to ground planes;
‧ the orientation of the device is random; or
‧ the device is used in a harsh environment, subjected to force, dust and moisture.

The Ruggedised GeoHelix-P2 antenna is balanced, which isolates it from the device and enables the antenna to reject common mode noise resident on the device ground plane. The construction and materials of the antenna constrain its near-field to a very small volume, therefore materials near the antenna have negligible de-tuning effects and the antenna maintains its pattern and efficiency in the presence of dielectric loading. As a dielectrically-loaded antenna, the Ruggedised GeoHelix-P2 acts as its own filter, attenuating signals from common GSM and ISM frequencies by as much as 30dB without external filtering. The SL1203A has a built in DC Block to enable direct connection to receivers with DC on their input pin.
