The LP-400-6000 is a strategic-grade, ultra-wideband High Performance Log Periodic Dipole Antenna (LPDA) designed for seamless directional coverage from 400 MHz to 6000 MHz. Enclosed in a heavy-duty Fiberglass Radome, this antenna provides a definitive "single-unit" solution for the entire modern tactical and commercial spectrum, including military UHF, 4G/5G cellular, Wi-Fi 6, and S/C-Band satellite links. Its all-welded 6063T6 aluminum architecture ensures a consistent 8 dBi gain and extreme mechanical survivability, making it the premier choice for high-power jamming and spectrum monitoring in the world's most severe environmental conditions.
Design: Total Spectrum Dominance
The LP-400-6000 is engineered for operators who require "total spectrum visibility" without the logistical burden of multiple antenna swaps.
- Ultra-Wideband Efficiency: By utilizing full-sized radiating elements without lossy loading techniques, the antenna maintains high radiation efficiency and a stable 8 dBi gain across the entire 5.6 GHz bandwidth.
- Rugged Fiberglass Radome: The high-tech fiberglass enclosure offers exceptional RF transparency and structural strength. It shields internal elements from corrosive saline air, acid rain, and ice formation. Its tapered shape ensures a low wind profile even in 200 Km/Hr gusts.
- Polarization Agility: While standard for Linear (Vertical or Horizontal) polarization, an optional adapter plate allows for +/- 45-degree slant polarization, critical for modern MIMO cellular and tactical data link intercepts.
Construction: MIL-SPEC Industrial Hardening
Constructed from 6063T6 architectural anodized aluminum alloy, the LP-400-6000 is built for rapid installation and a long operational service life.
- PIM-Free Welded Architecture: All elements are fully welded to the support booms to prevent RF inter-modulation and ensure mechanical stability under extreme vibration or shock (MIL-STD-810G).
- Marine-Grade Durability: All hardware is made of marine-grade stainless steel. The unit is finished in Olive Green powder coating, providing superior resistance against salt fog and humidity in coastal zones.
- Direct D.C. Grounding: Operates at D.C. ground, providing a low-resistance path for lightning protection and suppressing atmospheric static for an ultra-quiet noise floor during sensitive monitoring.
Reliability: 100W Continuous-Duty Power
With a 100 Watt power handling capacity at 6 GHz, this antenna is robust enough for high-power jamming and strategic data links. The focused 60-degree horizontal beamwidth ensures precision signal targeting, while the 18 dB Front-to-Back ratio provides excellent isolation for equipment located behind the antenna.
Technical Features
- Ultra-Wideband 400–6000 MHz: One antenna for UHF, LTE, 5G, Wi-Fi 6, and C-Band.
- Rugged Fiberglass Radome: Elite protection against environmental degradation and visual detection.
- High-Efficiency 8 dBi Gain: Consistent directional precision across the entire band.
- MIL-STD-810G Certified: Tested for extreme temperature, shock, vibration, and salt fog.
- Rear-End Mounting Plate: Fast installation on 51mm (2-inch) masts with optimized patterns.
- Optional Slant Polarization: Adapter plate available for +/- 45-degree tactical requirements.
- Direct Ground Protection: Integrated lightning protection and enhanced noise immunity.
EW & Monitoring Guide: 400–6000 MHz Strategy
The LP-400-6000 is a premier tool for the modern, signal-dense urban battlefield, covering everything from UHF tactical radios to high-frequency C-band links.
1. Mastering Microwave Multipath
In city centers, signals reflect sharply off glass and metal. The 60-degree horizontal beamwidth acts as a "spotlight," allowing an operator to scan for the strongest reflected path (Multipath Exploitation) when a direct line-of-sight is blocked.
2. Tactical Stealth
The Fiberglass Radome serves as RF camouflage. By obscuring the internal elements, it prevents an adversary from visually identifying which frequency band (e.g., 400 MHz vs. 5.8 GHz) is being targeted, providing a critical layer of tactical security.
3. High-Power Jamming Success
To disrupt high-speed 5G or Wi-Fi 6 links, a high Jamming-to-Signal (J/S) ratio is required. The 8 dBi gain concentrates power into a focused cone, exponentially increasing the Effective Radiated Power (ERP) on the target receiver.
Design Features: The LP-400-6000 log periodic dipole antenna log periodic dipole antenna uses 6063T6 ultra corrosion resistant architectural anodized aluminum alloy is designed to provide wideband directional radio signals from 400 to 6000 MHz frequency band. The extra spacers are used between the support booms to improve mechanical durability of antenna. The mounting bracket is welded at the back end of the dual booms of log periodic antenna which permits to change the polarization from horizontal to vertical and vice-versa. This log periodic dipole antenna system is particular suitable for transmission, reception or monitoring and jamming application due to its broadband design feature and small size. This log periodic antenna provides strong performance over the entire band. Log periodic antenna does not use loading technique to reduce the overall size of array.
