## **1.** Introduction 

The Bolt, A.80 is a high gain GNSS L1 & L2(GPS/GLONASS/Galileo/BeiDou) antenna that features very high out of band rejection and can handle large bursts of power from nearby transmitters. These characteristics make the A.80 ideal for applications where the antenna will be placed near high-power transmitters, such as cellular base stations or radar systems. 

The A.80 utilizes a very high efficiency (>70%) patch antenna that has been tuned for best possible performance within the enclosure to maximize signal quality. The internal LNAs have very low noise figure to maintain excellent signal quality throughout the entire signal chain. The signal chain also features carefully selected and placed SAW filters that collectively allow for very sharp signal attenuation outside of the intended frequency bands without negatively impacting in-band signal quality. 

The A.80 features excellent rejection across all non-GNSS frequencies to prevent overdriving or damaging your GPS receiver. At the 850/900MHz cellular bands, for example, the A.80 exhibits greater than 50dB of rejection. At the 1800/1900MHz cellular bands, it exhibits >65dB, making it best in class when out of band interference is a concern. Even with this excellent out of band attenuation, the A.80 maintains a low noise figure of 4dB and high gain of >21dB, making it an ideal solution for applications with longer cable runs where high cable loss is a concern. 

Cable lengths and connector types are customizable. Contact your regional Taoglas customer support team for further information.

## **6.1** Rooftop test 

In this section Taoglas will present the field test result for AA.200 antenna. The test was performed when the antenna was mounted on a static rooftop test set up in an open sky environment for at least 6 hours. 

Taoglas will show the field test results using the following receiver: 

## **1. U-blox ZED-F9P** 

## Receiver features: 

- Multi-band GNSS: 184-channel GPS L1C/A L2C, GLONASS: L1OF L2OF, Galileo: E1B/C E5b, BeiDou: B1I B2I, QZSS: L1C/A L2C 

- Multi ‑ band RTK with fast convergence times and reliable performance 

- Nav. update rate RTK up to 20 Hz 

- Position accuracy = RTK 0.01 m + 1 ppm CEP

Stock Shortage Specialist

When a component is unavailable, discontinued or has an unacceptable lead time, we tap into our network of vetted European and Asian distributors to source what you need — without compromising on quality or traceability.

Request a quote →

Compliant Alternatives

We identify pin-to-pin, electrically equivalent substitutes that meet the same certifications (RoHS, AEC-Q100, REACH) as your original specification — validated against datasheets, not just part numbers. Often at a lower cost.
