Product Name : GeoHelix-P2(SL1203D Rugged Passive Antenna)

Description : GeoHelix-P2(SL1203D Rugged Passive Antenna)


Product Description
Built on patented PowerHelix® filtering antenna technology, the Ruggedised SL1203
GPS antenna is the smallest quadrifilar helix antenna available, providing high performance in difficult GPS applications. The Ruggedised SL1203 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;

• the device is used in a harsh environment, subjected to force, dust and moisture; or

• the orientation of the device is random.

The Ruggedised SL1203 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 SL1203 acts as its own filter, attenuating signals from common GSM and ISM frequencies by as much as 30dB without external filtering. The SL1203 has a built in DC Block to enable direct connection to receivers with DC on their input pin.

The SL1203A and SL1203C have the same external dimensions with the only difference being the integrated O-ring on the SL1203C. The SL1203D also has the integrated O-ring and different external profile.
