Sector antenna 2.4 GHz

Q: What is an electronic warfare (EW) antenna, and what is it used for?

An EW antenna is a component of an electronic warfare system used to transmit jamming signals within a specific frequency range. Such antennas are designed to affect UAV control channels, telemetry links, and data transmission systems.

Q: What antennas are used in EW systems?

EW systems use quadrifilar, sector, omnidirectional, and other specialized antennas operating across different frequency ranges. The choice of antenna type depends on the mission, the required coverage sector, and the types of UAVs the system is designed to counter.

Q: What is the difference between an omnidirectional and a sector antenna?

An omnidirectional antenna radiates a signal in a full 360-degree pattern, providing circular coverage around itself. A sector antenna concentrates the signal within a defined sector, enabling higher efficiency and stronger performance in a specific direction.

Q: What are quadrifilar antennas used for?

Quadrifilar antennas are used in dome-type electronic warfare systems to create a wide coverage area. Thanks to circular polarization, they ensure stable performance against UAVs regardless of their orientation in space.

Q: How to choose an antenna for an EW system?

When selecting an antenna, it is important to consider the operating frequency range, target type, system use case, and required coverage area. It is also essential to take into account polarization type, gain level, and allowable power handling.

Q: What frequencies do BlueBird Tech EW antennas support?

Depending on the model, BlueBird Tech antennas operate across different frequency ranges from 160 MHz to 6 GHz. This allows them to be used in systems designed to counter FPV drones, various types of UAVs, and other wireless communication systems.

Q: What does antenna gain mean?

Antenna gain indicates how effectively an antenna focuses the signal in a specific direction. The higher the dBi value, the more efficiently the antenna concentrates radiated energy into a defined area.

Q: Why is choosing the correct antenna polarization important?

Polarization affects system performance and interaction with the target. Depending on the type of UAV and the operational scenario, antennas with circular, vertical, or horizontal polarization may be used.

Q: What antennas are suitable for dome-type EW systems?

Quadrifilar antennas with circular polarization are most commonly used in dome-type electronic warfare systems. They enable uniform coverage around an object and provide protection from multiple directions.

Q: Can one antenna be used for different frequency ranges?

Each antenna is designed to operate within a specific frequency range. For maximum efficiency, it is necessary to use models whose specifications match the EW system’s operating parameters.

The sector antenna 2.4 GHz is an EW component for countering DJI Mavic drones, featuring linear vertical polarization and an operating power of 50 W.
