GNSS Bias Tee

  • Model: NTS-BiasT

  • Connectivity: SMA

Product Overview

The NTS-BiasT enables an external DC supply to be inserted into an antenna feed and passed to the GNSS Antenna.

Key Features

  • Receiver and Antenna Compatibility: Higher voltage +5V antennas can be safely used with low voltage +3v3 GNSS receivers.

  • Versatile Power Placement: Ideal for extended length feeder installations, allowing antenna power to be supplied closer to the antenna itself.

  • Zero Signal Degradation: Being a passive device, it has no detrimental effect on receiver performance.

  • Exceptional Bandwidth: Insertion loss is exceptionally low, featuring a wide pass band that extends both above and below common GNSS frequencies.

GNSS Bias Tee with Gain

GNSS Bias Tee - With Gain

  • Model: NTS-BiasT-A

Product Overview

The NTS-BiasT-A enables an external DC supply to be inserted into an antenna feed and passed to the GNSS Antenna. Higher voltage +5V antennas can be used with low voltage +3v3 GNSS receivers.

Key Features

  • Active Signal Gain: Specially engineered for extended length feeder installations. The integrated gain of approximately 6dB enables lengthy cable runs between the antenna and receivers without signal loss.

  • Optimized Bandwidth: Features a wide pass band extending both above and below common GNSS frequencies.
