A.85 – Bolt Dual Band L1 and L5 GNSS Low Profile Permanent Mount Antenna


Bolt Dual Band L1 and L5 GNSS Permanent Mount Antenna

The Bolt, A.85 is a high gain GNSS L1/L5 (GPS/GLONASS/Galileo/BeiDou) antenna that features very high out of band rejection and can handle large bursts of power from nearby transmitters allowing the antenna to always remain operational. These characteristics make the A.85 ideal for applications where the antenna will be placed near high-power transmitters.

Typical Applications Include:
– Commercial Transportation
– Asset and Container Tracking
– Small Cell GNSS Towers
– Precision Agriculture

The A.85 Bolt Dual Band L1 and L5 GNSS permanent mount antenna utilizes a very high efficiency (>60%) 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.85 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.85 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.85 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.
