PacCrest Radio modem System - Available for rental, hire and ex-rental purchase from Ashtead Technology.
The RFM96W radio modem family provides high performance and high reliability wireless data communication. Designed specifically for portable and mobile field applications, the rugged RFM96W features 100% duty cycle operation, various RF power outputs, and compact size. Advanced techniques such as forward-error-correction with data scrambling enable reliable operation in low or fading signal conditions.
The RFM96W features a watertight design for operation in unprotected environments common in field applications. Models are available with receive only, 2W, or 35W RF power outputs. 35W units can be switched to 2W operation for power conservation or use in activities where low power output is appropriate. All models feature a fully synthesized multi-channel radio that allows operation on all frequencies in the supported UHF or VHF bands.
Standard equipment includes a comprehensive user s manual with programmer s guide, power/data cable and configuration software. Optional power supplies, antennas and antenna mounts are also available.
