LHCP Hemispherical Antenna
1100-1900MHz LHCP Hemispherical Antenna
The LHCP Hemispherical Antenna is a wideband circularly polarized antenna designed for RF communication, wireless signal transmission, signal monitoring and other applications requiring reliable LHCP coverage. Operating across 1100-1900 MHz, the antenna provides stable performance over a broad frequency range.
Featuring left-hand circular polarization (LHCP) and a 5 dBi gain, this hemispherical antenna provides a wide radiation pattern with 120° ±10° horizontal and vertical 3 dB beamwidths. The combination of wide beam coverage and circular polarization makes it suitable for applications where signal reception or transmission from different directions is required.
The antenna is designed with a 50 Ω impedance and VSWR ≤1.5, ensuring good impedance matching and efficient RF performance. With a maximum input power of 100 W, it can support higher-power RF systems and demanding field applications.
The compact Φ150 × 80 mm antenna features a durable premium ABS radome, providing protection for the internal antenna components while maintaining a lightweight and practical design. The antenna weighs approximately 0.62 kg and uses an N-Female connector with flange mounting.
For outdoor and harsh-environment applications, the antenna provides DC-ground lightning protection, IP65 water ingress protection, and an operating temperature range of -40°C to +60°C. Its vibration performance complies with MIL-STD-810G, while the structure is designed to withstand wind speeds up to 160 km/h.
