The 380-2000MHz Planar Helical Antenna: Versatile Wireless Connectivity Redefined
The 380-2000MHz Planar Helical Antenna (Model: MOP03820-0.5B) stands as a high-performance solution engineered to meet the rigorous demands of modern wireless communication systems. With right-handed circular polarization (RHCP) at its core, this antenna is purpose-built for a wide array of applications, including 4G LTE networks, Internet of Things (IoT) deployments, and fixed wireless access (FWA) setups. Whether installed in small-to-medium commercial spaces, industrial workshops, or outdoor equipment monitoring stations, this antenna delivers dependable signal coverage and transmission stability in virtually any environment.
Its design as both an indoor and outdoor universal antenna ensures unmatched adaptability. The robust operational temperature range of -40°C to +55°C, paired with a storage temperature range of -50°C to +65°C, guarantees consistent performance even under extreme weather conditions or harsh industrial settings. This resilience makes the antenna an ideal choice for scenarios where reliability is non-negotiable.
Constructed as an Alufer Cavity Antenna, this model leverages the exceptional durability of an alufer material cavity, which is coated with a grayish-blue (GY09) pigment. This construction enhances structural strength and resistance to environmental wear, significantly extending the antenna’s service life. These attributes directly contribute to the long-term value of the 380-2000MHz Planar Helical Antenna in any deployment.
Key Features and Performance of the 380-2000MHz Planar Helical Antenna
Wideband Operation and Circular Polarization Advantages
Operating across a broad frequency spectrum of 380MHz to 2000MHz, the 380-2000MHz Planar Helical Antenna provides excellent signal propagation characteristics. Its right-handed circular polarization minimizes signal degradation from reflections and multipath interference, ensuring cleaner and more reliable transmission. This makes it particularly suitable for IoT device networking in commercial buildings and outdoor signal coverage for remote equipment monitoring in industrial yards.
Gain and Beam Width Specifications
The antenna delivers a gain of ≥-0.5dB, with a beam width of ≥90° across the full operating range. For critical low-frequency segments, the absolute gain remains better than -4dB for 380 to 500MHz, while mid-to-high frequencies from 500 to 2000MHz achieve an absolute gain better than -2dB. This performance ensures effective signal coverage and transmission stability, even in challenging environments.
Additional performance metrics further validate its reliability: a standing wave ratio (VSWR) of ≤2.5 minimizes signal reflection, and a back lobe specification of ≤-12dB reduces interference from unwanted directions. The SMA-K type stainless steel connector ensures secure, low-loss signal connectivity, which is vital for maintaining system integrity.
