JCM6-2025

The JCM6-2025 is a high-performance Broadband Manpack Jammer Collinear Antenna specifically engineered for the 2000–2500 MHz (2.0–2.5 GHz) spectrum. This frequency range is a critical theater for Electronic Warfare, encompassing key UMTS/3G, 4G LTE, and 2.4 GHz ISM (Wi-Fi/Bluetooth/Drone) bands. By utilizing aerospace-grade aluminum radiating elements, the JCM6-2025 delivers a consistent 6 dBi gain and a focused 36-degree vertical beamwidth, providing a robust electronic "denial bubble" for dismounted tactical teams.

Design: Unified Spectrum Defense & Tactical Mobility

The JCM6-2025 is designed for operators who require "zero-gap" protection across multiple high-frequency communication standards without the logistical burden of multiple antennas.

• Broadband 2.0–2.5 GHz Coverage: This antenna provides a unified solution for the entire 500 MHz wide band. It ensures consistent protection against various 2.1 GHz UMTS nodes and the globally saturated 2.4 GHz Wi-Fi and drone control bands.
• Superior 6 dBi Omni Gain: Achieving 6 dBi in a 450mm configuration focus RF energy horizontally to establish a dominant Jamming-to-Signal (J/S) ratio, significantly increasing the standoff range against adversary devices.
• Optimized 36° Vertical Beamwidth: The antenna compresses its radiation into a 36-degree vertical beam. This ensures that the 50W of transmitter power is directed toward the horizon where threats are most likely to be located, rather than wasting energy on the sky.
• High-Offset Radiator Position: Internal elements are positioned in the upper portion of the radome. This design choice ensures that the "denial disc" is projected above the operator's head and equipment, minimizing signal absorption by the operator's own gear.

Construction: MIL-Standard Hardening

Built for the rigors of modern combat, the JCM6-2025 is a "zero-tuning" tactical asset designed for rapid deployment.

• Rugged 6063T6 Aluminum Radiators: The use of ultra-corrosion-resistant aluminum alloy ensures superior conductivity and thermal stability, maintaining a smooth 2.5:1 VSWR across the entire 500 MHz bandwidth.
• Mechanical Resilience: The 28mm diameter radome is made of high-strength ABS, which is mechanically robust yet 100% RF-transparent. The support pipe and mounting flange are powder-coated in Military Green to protect against severe environmental conditions.
• Tactical Versatility: The antenna mounts directly via an N-Male termination. For high-mobility missions, the JCM6-2025-S version (with integrated spring base) is available to absorb mechanical shocks.

Technical Features
