Overview: LP-30-300 High-Gain Tactical Log Periodic Dipole Antenna
The LP-30-300 is a professional-grade, heavy-duty Log Periodic Dipole Antenna (LPDA) engineered for high-performance wideband operation across the 30–300 MHz frequency spectrum. delivering a consistent 9 dBi gain and a massive 1000-Watt (1 kW) power handling capacity, this directional array is a premier solution for long-range VHF communications, wide-spectrum monitoring, and strategic Electronic Warfare (EW). Built from architectural-grade 6063T6 aluminum alloy, the LP-30-300 provides a flat gain response across its entire bandwidth without the use of lossy loading techniques, ensuring maximum radiation efficiency for mission-critical deployments.
Tactical Durability & Rapid Deployment
Hardened construction designed for quick assembly in Punishing Environments. The LP-30-300 is optimized for rapid field deployment. Despite its significant dimensions (4.8 meters long), the antenna features foldable elements and a fast-deployment stainless steel stud-and-nut system that allows for complete assembly in less than 10 minutes. To withstand extreme mechanical stress, the antenna utilizes reinforced spacers between support booms and is finished with a protective powder coating. Its 180 Km/Hr wind rating and Type 316 marine-grade stainless steel hardware ensure long-term structural integrity in corrosive coastal or high-vibration tactical theaters.
Operational Efficiency
Broadband precision and signal integrity achieved through high-quality materials. By utilizing square tube aluminum support booms and round tube radiating elements, the LP-30-300 maintains high structural symmetry. This geometry results in a directional radiation pattern with a 16 dB Front-to-Back ratio, effectively isolating target signals from background noise and rearward interference. The antenna operates at D.C. ground, providing a direct low-resistance discharge path to protect sensitive radio hardware from lightning-induced surges and static buildup.
Detailed Technical Features
- VHF Wideband Mastery: Seamless continuous coverage from 30 MHz to 300 MHz, supporting Low-Band and High-Band VHF tactical communications with a single aperture.
- High-Gain Directional Output: Delivers a stable 9 dBi gain, outperforming smaller loaded antennas in both transmission range and intercept sensitivity.
- Dual-Polarization Versatility: The mounting arrangement permits rapid switching between Horizontal and Vertical polarization to meet specific mission requirements.
- Industrial Power Capacity: Engineered to handle 1000 Watts (1 kW) of RF power, making it ideal for high-intensity jamming and strategic broadcast.
- Logistics-Optimized Design: Foldable, two-segment elements reduce the 5-meter width to a manageable 2.5-meter shipping length.
- Direct Ground Lightning Safety: Integrated DC Ground architecture ensures hardware survivability during electrical storms and reduces environmental noise.
- Marine-Grade Hardware Suite: All assembly components are fabricated from Type 316 Stainless Steel to prevent galvanic corrosion in saline or tropical environments.
- Zero Loading Design: Pure dipole array engineering ensures no signal loss associated with size-reduction coils, maximizing effective radiated power.
EW, SIGINT & Monitoring Compatibility
- Electronic Warfare (EW): Acts as a high-intensity directional source for jamming VHF tactical data links, RCIED triggers, and voice communications.
- Signals Intelligence (SIGINT): The highly directional beamwidth (100° Horizontal / 65° Vertical) facilitates accurate emitter triangulation and the interception of weak, long-range signals.
- Spectrum Surveillance: Its massive 270 MHz frequency response makes it a "single-antenna" solution for persistent monitoring across public safety, maritime, and military bands.
Key Advantages & Applications
Key Advantages:
- Consistent Gain Profile: Unlike Yagi antennas, this LPDA maintains a flat 9 dBi gain across the entire 30-300 MHz window.
- Heavy-Duty Mechanical Build: Reinforced architectural aluminum booms designed for permanent or rapid-deploy tactical installations.
- Multipath & Noise Immunity: DC Grounding and high Front-to-Back ratio ensure a clean signal-to-noise ratio in cluttered theaters.
Key Applications:
- Tactical Communications: High-reliability VHF ground-to-ground and ground-to-air links.
- Directional Jamming: High-power denial of services in the 30-300 MHz spectrum.
- Mobile Command Posts: Rapidly deployable directional antenna for field-based HQ and surveillance units.
Coastal Surveillance: Designed for long-term deployment in saline environments to monitor maritime and emergency frequencies.
Design Features: The LP-30-300 log periodic dipole antenna use 6063T6 ultra corrosion resistant architectural anodized aluminum alloy and designed to provide wideband directional transmission/reception of radio signals from 30-300 MHz bands. The specially designed mounting arrangement results in fast installation. The extra spacers are used between the support booms to improve mechanical durability of log periodic antenna. The antenna can be assembled in less than 10 minutes. This log periodic dipole antenna system is particular suitable for transmission, reception, monitoring, scanning and jamming applications due to its broad band design feature. This high gain LPA provides strong performance over the entire frequency of 30-300 MHz as the LPDA does not use loading technique to reduce the overall size of array.
