Product Specifications

The bandpass preselector is an essential component for master reception systems, specifically designed to ensure the elimination of external noise sources. This preselector offers optimal protection to the receiver when installed between the receiver multicoupler and the antenna, ensuring clean and interference-free reception.

Telewave provides sharp-skirt selectivity with minimal insertion loss. Each unit is manufactured with high-strength materials to ensure superior performance and long service life, and each preselector is factory tuned to customer specifications, reducing the need for additional field adjustments.
