Ultra enhanced 8-element anti-interference antenna SLA165-8B1L1

The SLA165-8B1L1 anti-jamming antenna integrates eight B1L1 receiving antennas, an eight-channel RF receiving module, and an anti-jamming processing module, outputting jamming-free RF signals. The antenna can simultaneously resist up to seven suppressive jammers from different directions, fully protecting GNSS satellite signals under strong jamming, meeting the GNSS signal reception requirements of various carriers in complex suppressive jamming electromagnetic environments.

This antenna integrates the antenna source, RF, anti-jamming module, and upconversion in a compact design, meeting the requirements of high reliability and low cost. Utilizing fully proprietary adaptive nulling antenna and space-time adaptive filtering technology, it significantly improves the availability of GNSS satellite signals in complex electromagnetic environments and offers robust resistance to various types of suppressive interference, including but not limited to single-carrier, swept-frequency, pulse, broadband modulation, sawtooth, triangle, and any combination thereof.

General installation requirements

1. The underside of the anti-jamming antenna is a metal heat dissipation surface. When installing, ensure that the bottom has good heat dissipation conditions. It is recommended to closely attach the underside to other metal surfaces during installation to achieve better heat dissipation.

2. The top surface of the anti-jamming antenna is the GNSS signal receiving antenna. To ensure good GNSS signal reception, it is recommended to use it in an unobstructed view of the sky. If used in an obstructed environment, please contact our after-sales staff. We will provide a suitable installation method based on the obstruction conditions.

Precautions

1. The device's power supply voltage range is 9V to 36V. The recommended typical operating voltages are 12V, 20V, or 28V.

2. Please connect all interfaces while the power is off. Hot-swapping is not permitted. It is recommended to use the dedicated power supply cable provided by our company for power supply. If using a custom-made power supply cable, please ensure that the signal pins of the custom-made cable's connector comply with the interface specifications.

3. The steady-state operating power of the anti-jamming antenna is less than 12W, and the instantaneous maximum power does not exceed 15W. It is recommended that the maximum output power of the power supply for the anti-jamming antenna be no less than 20W.

4. Remember not to exceed the power supply range, do not disassemble the antenna shell, and contact our after-sales personnel if a malfunction occurs. If necessary, return the product to the factory for processing.
