| LP-100-1000 | High Gain Log Periodic Dipole Antenna | 100-1000MHz | 9 dBi |
The LP-100-1000 is a strategic-grade, high-gain Log Periodic Dipole Antenna (LPDA) engineered for relentless directional performance across the 100–1000 MHz spectrum. Covering nearly a full gigahertz of bandwidth, this antenna is a unified solution for High-VHF air-to-ground links, the entire UHF tactical band, and low-end L-band monitoring. Built from 6063T6 architectural aluminum and featuring a rapid-assembly stud system, it delivers a stable 9 dBi gain and superior front-to-back isolation, making it the definitive choice for signal intelligence (SIGINT), high-power jamming, and broad-spectrum surveillance.
Design: Wideband Mastery & Tactical Response
The LP-100-1000 is optimized for operators who require gapless spectrum coverage from 100 MHz to 1 GHz without the logistical burden of multiple antennas.
- Elite 9 dBi Gain Efficiency: By utilizing full-sized radiating elements across its 1.8-meter frame, the LP-100-1000 maintains superior radiation efficiency and a focused 65-degree horizontal beamwidth. This ensures maximum energy concentration for both reception and high-power transmission.
- Rapid 5-Minute Assembly: Featuring foldable elements and a stainless steel stud system, the antenna can be fully assembled by two technicians in less than 5 minutes. This facilitates rapid "jump" missions and mobile command post setups.
- Rear-End Mounting Advantage: The antenna is supplied with a rear-end mounting bracket as standard, ensuring the support mast remains completely outside the radiation pattern to prevent gain degradation. A "Center of Gravity" mount is available for specialized weight-balanced deployments.
Construction: Combat-Tier Hardening
Constructed from 6063T6 architectural anodized aluminum alloy, the LP-100-1000 is built for strategic longevity in active combat zones and severe climates.
- MIL-STD-810G Certified: Rigorously tested for extreme temperature, shock, vibration, rain, and salt fog. It is specifically treated for survival in coastal, monsoon, or desert environments.
- Marine-Grade Durability: All fasteners (screws, nuts, and bolts) are made of Type 316 marine-grade stainless steel. The entire unit is protected by an epoxy-based Olive Green powder coating for total corrosion resistance and tactical low visibility.
- Integrated Safety: Operates at D.C. ground, providing a low-resistance discharge path for lightning and suppressing atmospheric static to ensure an ultra-quiet noise floor for high-sensitivity surveillance.

Integration Guide: Dominating the VHF/UHF Spectrum
1. Precision Signal Isolation
In the signal-dense 100-1000 MHz band, isolating specific tactical or aviation links requires a surgical directional focus.
- The Precision Advantage: The focused 65-degree beamwidth acts as a directional "spotlight." This allows an operator to isolate a specific target while physically "nulling out" interference from neighboring channels or reflective obstacles.
2. Tactical Jamming (EW) Strategy
At 250 Watts, the LP-100-1000 acts as a powerful directional floodlight. Its 9 dBi gain acts as an RF magnifying glass, concentrating energy into a focused cone, exponentially increasing your Effective Radiated Power (ERP) compared to an omnidirectional antenna.
3. Polarization Agility in Complex Terrain
While most tactical networks are vertically polarized, urban reflections can rotate signals. The LP-100-1000’s flexible mounting permits both Vertical and Horizontal orientation, ensuring you can match the orientation of the incoming wave to maintain a stable intercept.
Strategic EW & SIGINT Guide: 100–1000 MHz Wideband Dominance
The LP-100-1000 is a surgical "all-in-one" tool for the 0.1 to 1.0 GHz spectrum. This range is the operational core of modern military coordination, hosting High-VHF Military Aviation, the entire UHF Tactical Band, and low-band L-Band data links. In a battlespace defined by high-speed frequency hopping and urban interference, the LP-100-1000’s 9 dBi gain and 23 dB cross-polarization discrimination provide the fidelity required for mission success.
1. Mastering the VHF/UHF Landscape
Across the 100–1000 MHz range, radio waves transition from terrain-following behaviors to strictly "optical" line-of-sight propagation.
- The Precision Advantage: The focused 65-degree horizontal beamwidth of the LP-100-1000 acts as an RF "spotlight." This allows an operator to isolate a specific aircraft's transmission or a tactical repeater while physically "nulling out" interference from neighboring urban noise.
- Range Extension: Every 6 dB of gain effectively doubles your reception range. The 9 dBi gain allows you to pull in weak signals from distances where standard omnidirectional antennas would only see static.
2. Defeating Urban Multipath & Polarization Rotation
UHF signals (above 300 MHz) reflect sharply off glass, metal, and concrete. Each reflection can cause the signal's polarization to shift—a phenomenon known as Polarization Rotation.
- The "Null" Problem: Most tactical handhelds are vertically polarized. If a signal reflects off a slanted roof or metal structure, it may arrive at your site with a significant horizontal shift. A standard vertical antenna would experience a signal dropout of up to 20 dB.
- The Tactical Solution: The LP-100-1000 features a flexible mounting arrangement that allows operators to switch between Horizontal and Vertical polarization in seconds. Its superior 23 dB Cross-Polarization Discrimination ensures that when you switch polarizations, you are truly isolating the target signal from background clutter.
3. High-Power Jamming & J/S Ratio Optimization
To successfully disrupt a target link (e.g., a 400 MHz emergency net or a 900 MHz telemetry uplink), you must achieve a superior Jamming-to-Signal (J/S) ratio at the victim’s receiver.
- 250W Continuous Power: The LP-100-1000 acts as a powerful directional "floodlight." Its 9 dBi gain acts as an RF magnifying glass, concentrating 250 Watts of energy into a focused 65-degree cone.
- ERP Advantage: This concentration exponentially increases your Effective Radiated Power (ERP). This allows an operator to successfully "drown out" a legitimate signal from several kilometers away, even when the adversary is using high-power mobile transmitters.
4. "Silent" Monitoring: D.C. Grounding & Noise Floor
For sensitive SIGINT operations, the "Noise Floor" is the ultimate enemy. High-speed wind moving across 1.8 meters of aluminum elements creates Precipitation Static (P-Static).
- The Solution: The LP-100-1000 is D.C. Grounded. It constantly bleeds off this static charge to the mast and earth. This ensures the lowest possible noise floor, allowing you to detect low-power "hidden" transmissions or weak signals that would be buried in the static of an ungrounded antenna.
Tactical Deployment Checklist
- Rapid 5-Minute Setup: Take full advantage of the foldable elements. In modern EW, speed is survival. The LP-100-1000's speed of assembly (under 5 minutes) is a key survivability feature for "jump" missions.
- Cable Integrity: In the 1000 MHz (1 GHz) range, cable loss becomes significant. Do not use standard RG-58. Use LMR-400 or LMR-600. Every 3 dB of cable loss effectively cuts your jamming power or reception sensitivity in half.
- Rear-Mount Advantage: Since the mount is at the rear of the boom, the 2-inch metal mast remains completely behind the antenna. This prevents "Mast Shadowing," which would otherwise distort the 65-degree beam.
- Boresight Alignment: Because the beamwidth is 65 degrees, a 32-degree error in alignment will drop your gain significantly. Use a compass to ensure the antenna is pointed exactly at the target sector for maximum intercept probability.
Design Features: The LP-100-1000 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 100-1000 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 antenna. This log periodic dipole antenna system is particular suitable for transmission, reception, monitoring, surveillance, scanning and jamming applications due to its broad band design feature. This high gain LPA provides strong performance over the entire frequency of 100-1000 MHz as the LPDA does not use loading technique to reduce the overall size of array. The high gain log periodic antenna can be assembled in less than 5 minutes by 2 technicians. Antenna is supplied with rear end mounting. The antenna can also be supplied with mounting at center of gravity on request.
