The LP-800-2700 is a high-performance Log Periodic Dipole Antenna (LPDA) designed for wideband directional communication across the 800–2700 MHz spectrum. Protected by a heavy-duty Fiberglass Radome, this antenna is engineered for elite durability and "all-in-one" coverage of modern wireless bands, including GSM, 3G, 4G LTE, Wi-Fi, and L/S-Band frequencies. Its all-welded, non-loaded aluminum architecture ensures a consistent 9 dBi gain and superior mechanical integrity, making it the definitive choice for high-power jamming, spectrum monitoring, and mission-critical communications in the world's harshest environments.
Design: Strategic Band Mastery & Environmental Survival
The LP-800-2700 is designed for operations that require a single antenna to bridge the gap between legacy cellular bands and modern high-speed data links.
- Elite Fiberglass Radome Protection: The high-tech fiberglass enclosure is built for survivability. It offers exceptional RF transparency and structural strength, shielding the internal elements from corrosive saline air, acid rain, and ice formation while maintaining a low wind profile.
- Full-Spectrum Unloaded Gain: By utilizing a full-sized, non-loaded element design, the antenna maintains a stable 9 dBi gain and high radiation efficiency across the entire 1900 MHz bandwidth, ensuring no signal loss at the frequency extremes.
- Aero-Dynamic Tapered Design: The enclosure is specifically shaped for low wind loading (200 Km/Hr rating) and minimal ice accumulation, providing an aesthetically pleasing and tactical appearance for covert or high-profile installations.
Construction: Marine & Industrial Hardening
Constructed from 6063T6 architectural anodized aluminum alloy, the LP-800-2700 is built for rapid deployment and strategic longevity.
- PIM-Free Welded Architecture: Radiating 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 Hardware: All fasteners, including screws, nuts, and bolts, are made from high-grade stainless steel. The entire antenna is finished in Olive Green powder coating for superior corrosion resistance 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 missions.
Reliability: 150W Continuous-Duty Power
With a 150 Watt power capacity at 2700 MHz, 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 sensitive equipment located behind the antenna.

EW & Monitoring Guide: Urban SIGINT & Wideband Strategy
The LP-800-2700 is a specialized tool for the modern, signal-dense urban battlefield. Covering 0.8 GHz to 2.7 GHz, it monitors the backbone of commercial communications and tactical data links.
1. Mastering Urban Multipath
In city centers, signals reflect 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., 800 MHz vs. 2600 MHz) is being targeted, providing a critical layer of tactical security.
3. High-Power Jamming Success
To disrupt a high-speed LTE or Wi-Fi link, a high Jamming-to-Signal (J/S) ratio is required. The 9 dBi gain concentrates 150W of power into a focused cone, exponentially increasing the Effective Radiated Power (ERP) on the target receiver.
Strategic EW & SIGINT Guide: Multi-Band Urban Dominance
The LP-800-2700 is a mission-critical asset for the 800–2700 MHz range, a spectrum that hosts the world’s most vital commercial and tactical data links. This includes GSM/LTE cellular networks, Wi-Fi (2.4 GHz), and S-Band satellite services. In this high-frequency environment, signal behavior is dominated by "Line-of-Sight" physics and high-reflectivity, making the directional precision of the LP-800-2700 a mandatory requirement for SIGINT and Electronic Warfare (EW).
1. Exploiting Urban Multipath & Polarization Shifting
At frequencies between 0.8 GHz and 2.7 GHz, radio waves behave increasingly like light. They reflect sharply off glass, metal, and concrete. Each reflection can cause the signal's polarization to shift or rotate.
- The "Drop-Out" Problem: A target's signal may bounce off several buildings before reaching your antenna. If your antenna is vertically fixed and the signal arrives rotated horizontally, you could experience a 20 dB signal loss.
- The Strategic Scan: The 60-degree horizontal beamwidth of the LP-800-2700 acts as an RF "spotlight." By scanning the horizon, an operator can identify the strongest reflected path (Multipath Exploitation) rather than just pointing at the target's direct coordinates, ensuring a stable intercept even in "RF shadows."
2. Tactical Stealth: The Fiberglass Radome Advantage
In Electronic Warfare, the Fiberglass Radome serves as more than just a weather shield—it provides a critical layer of "RF Camouflage."
- Visual Deception: Without a radome, an adversary with binoculars can see the internal elements. They would immediately know if you are monitoring the low-band (800 MHz) or the high-band (2700 MHz) based on which elements are active.
- Directional Obscuration: The tapered radome hides the exact "boresight" (pointing direction) of the antenna. This makes it impossible for an opponent to determine exactly which window, vehicle, or tower your team is currently targeting.
3. High-Power Jamming & J/S Ratio Optimization
To successfully disrupt a high-speed LTE or Wi-Fi data link, you must achieve a superior Jamming-to-Signal (J/S) ratio at the victim’s receiver.
- Power Density Focus: The 9 dBi gain acts as a "magnifying glass" for your RF energy. Instead of scattering 150W in all directions, the LP-800-2700 focuses that energy into a tight 60-degree cone.
- Effective Radiated Power (ERP): This concentration exponentially increases your ERP. By focusing the energy, you can successfully "drown out" a legitimate signal from several kilometers away, even when using relatively low input power.
4. "Quiet" Monitoring: D.C. Grounding & Noise Floor
At frequencies approaching 3 GHz, sensitive SIGINT receivers are highly vulnerable to "Noise Floor" elevation, which can mask low-probability-of-intercept (LPI) signals.
- Static Suppression: High-speed wind or dry air moving across the fiberglass radome creates "Precipitation Static" (P-Static). On an ungrounded antenna, this creates an electronic "hiss" that masks weak signals.
- The Solution: The LP-800-2700 is D.C. Grounded. It constantly bleeds off this static charge to the mast and earth, ensuring the lowest possible noise floor for detecting "hidden" or low-power transmissions.
High-Frequency Tactical Deployment Checklist
- Microwave Cable Integrity: At 2700 MHz (2.7 GHz), cable loss is severe. Avoid 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.
- Boresight Alignment: Because the beamwidth is 60 degrees, a 30-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.
- Connector Weather-Proofing: Microwave connectors are highly sensitive to moisture. A single drop of water in the N-type connector will cause a massive VSWR spike at 2.7 GHz. Use butyl rubber tape for a primary moisture seal on all outdoor connections.
- Line-of-Sight (LOS): At these frequencies, even thin plywood or heavy foliage can attenuate the signal by 10–15 dB. Always attempt to find an elevated position with a clear optical path to the target area.
Design Features: The LP-800-2700 high performance log periodic dipole antenna uses 6063T6 ultra corrosion resistant architectural anodized aluminium alloy with welded elements. The complete antenna is supplied with powder coating finish to protect it further from severe environment conditions. The LP-800-2700 log periodic dipole antenna is designed to provide wideband directional transmission/reception of radio signals from 800 to 2700MHz bands. The extra spacers are used between the support booms to improve mechanical durability of antenna. This high power high gain log periodic dipole antenna provides strong performance over the entire frequency of 800-2700MHz as the LPDA does not use loading technique to reduce the overall size of array. Powder coating of the complete log periodic antenna provides extra protection against corrosion in saline weather present in coastal areas.
