The JCM7-1227 is a high-performance Manpack Jammer Collinear Antenna specifically engineered for the 1210–1240 MHz frequency range. This aperture is a critical tactical asset for the denial of satellite-based navigation and timing, specifically targeting the GPS L2 band. By providing a concentrated 7 dBi gain in a robust 600 mm form factor, it delivers the high power density required for dismounted Electronic Warfare (EW) teams to effectively neutralize military-grade GNSS signals.
Design: Precision GPS L2 Band Mastery
The JCM7-1227 is designed for operators who require surgical precision and extended standoff range in the 1.2 GHz spectrum.
- High-Efficiency 7 dBi Gain: Achieving 7 dBi in a portable configuration significantly expands the electronic "denial bubble." This gain level focuses RF energy horizontally to establish a dominant Jamming-to-Signal (J/S) ratio against weak satellite downlinks.
- Focused 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, maximizing signal saturation where ground-based or low-altitude threats are positioned.
- Direct Transmitter Integration: Featuring an N-Male termination, the antenna mounts directly onto the portable equipment. For high-mobility missions, the JCM7-1227-S version (with integrated spring base) is available to absorb mechanical shocks and protect the radio's RF port.
Construction: Combat-Tier Hardening
Built for the rigors of modern field operations, the JCM7-1227 is a "zero-tuning" tactical asset designed for rapid deployment.
- Rugged ABS Radome: Internal high-quality brass radiating elements are protected by a 25 mm diameter ABS radome. This housing is UV-stabilized and RF-transparent, shielding the internal architecture from ice, sand, and moisture without signal degradation.
- Lightweight & Agile: At only 600 mm (23.6 inches) and 350 grams, it balances the need for high-frequency gain with the physical requirements of a dismounted foot patrol.
- Ultra-Corrosion Resistance: Utilizing 6063T6 aluminum alloy and premium brass, the antenna is built to maintain electrical integrity in severe environmental conditions.
Technical Features
- Targeted 1210–1240 MHz Coverage: Optimized for GPS L2 band denial and signal suppression.
- 7 dBi Omni-Directional Gain: Significantly expands the jamming perimeter over standard whips.
- 50W RF Power Handling: Robust enough for continuous-duty portable EW and jamming operations.
- Superior VSWR (1.5:1): Ensures maximum power transfer and protects sensitive portable electronics.
- All-Weather Architecture: Cylindrical enclosure reduces wind loading and resists ice formation.
- Military Finish: Supplied in tactical Olive Green for low visual signature.
Design Features: The JCM7-1227 Jammer manpack collinear antenna is rugged all weather model, enclosed in a ABS radome, uses high quality brass radiating elements and does not require any field tuning or adjustments. The compact size of omni-directional antenna allows easy handling, shipping and highly suitable for transmitting, receiving including GPS L2 band without having the requirement of multiple antennas. Cylindrical enclosure is used for low wind loading and for minimal effect of ice formation on the antenna operation as well as providing an aesthetically pleasing appearance.
