High-Gain, High-Rejection Active GPS Timing Antenna with Integrated Lightning Induced Surge Protection

The Bolt A.93.A is a best in class high rejection timing antenna featuring high gain, excellent out-of-band rejection and integrated protection against lightning-induced surges. It comes in a compact external permanent mount enclosure that is IP67 rated and UV resistant. The A.93.A has greater than 28 dB LNA gain and excellent out-of-band rejection, characteristics that make it ideal for GPS/GLONASS/BeiDou timing applications where the antenna will be placed near transmitters, such as cellular, Wi-Fi, Bluetooth, etc.

The integrated filters feature outstanding rejection across all non-GNSS frequencies to prevent overdriving or damaging the GNSS receiver from nearby transmitters. At the commonly used LTE frequencies between 700MHz-1000MHz, the A.93 provides greater than 80 dB of rejection and between 1820MHz-3500MHz, it has greater than 60 dB of rejection.

Even with the superb out of band rejection, the A.93 maintains a very low noise figure of less than 2.2 dB. This low noise figure minimizes overall signal quality degradation typically caused by losses in transmission lines. The A.93 includes integrated protection against lightning-induced surges (IEC 61000-4-5, Class 4), thus removing the need for expensive external solutions.
