LPHP-700-2700

The LPHP-700-2700 is a professional-grade, radome-protected High Power Log Periodic Dipole Antenna (LPDA) engineered for comprehensive spectrum dominance across the 700–2700 MHz range. This ultra-wideband aperture is a unified solution for modern tactical and commercial applications, covering LTE 700, FirstNet, GSM, 3G, 4G LTE, Dual-Band Wi-Fi, and S-Band telemetry. Encased in a heavy-duty fiberglass radome with fully welded 6063T6 aluminum elements, it is specifically designed for high-intensity Electronic Warfare (EW), SIGINT, and high-power jamming in the most severe environmental conditions.

Design: Total Spectrum Dominance & High-Power Response

The LPHP-700-2700 is optimized for operators who require gapless visibility from the 700 MHz public safety bands up to the 2.7 GHz microwave range without switching hardware.

• Unified 700–2700 MHz Coverage: Replaces multiple dedicated antennas by providing a single high-gain aperture for cellular, tactical data links, and aeronautical monitoring.
• Non-Loaded Efficiency: By avoiding lossy loading techniques, the antenna maintains a stable 9 dBi gain and superior radiation efficiency across its entire 2000 MHz bandwidth.
• Fully Welded Element Integrity: All radiating elements are fully welded to the support boom. This critical design feature prevents RF inter-modulation (PIM) and ensures the antenna maintains its electrical fingerprint under the extreme heat of 250W continuous power or intense mechanical vibration.

Construction: Fiberglass Radome & MIL-STD Hardening

Housed in a heavy-duty fiberglass radome, the LPHP-700-2700 is built for continuous mission-critical performance in the world's most severe climates.

• Strategic Radome Protection: The ruggedized fiberglass enclosure provides 100% RF transparency while physically shielding the elements from ice formation, sand erosion, and salt fog. The tapered design ensures a low wind profile (200 Km/Hr) and prevents performance degradation in arctic or coastal environments.
• MIL-STD-810G Certified: Rigorously tested for shock, vibration, humidity, and fungus resistance. It is the premier choice for permanent naval installations, coastal monitoring, or mobile vehicle-mounted EW suites.
• Integrated Safety: Operates at D.C. ground, providing a direct discharge path for lightning and suppressing atmospheric static for an ultra-quiet noise floor during sensitive SIGINT intercepts.

Technical Features

• Elite 700–2700 MHz Bandwidth: Gapless coverage for modern digital and tactical signals.
• High-Efficiency 9 dBi Gain: Focused 60-degree horizontal beamwidth for long-range intercepts.
• 250W RF Power Handling: Robust capacity for continuous-duty jamming and high-power transmission.
• Fiberglass Radome: Ensures survivability and electrical stability in all weather conditions.
• DIN-Female Termination: Professional-grade connector fixed at the rear for maximum power handling and weather protection.
• Compact & Rugged: Only 450mm long and weighing 3 Kgs, ideal for high-vibration mobile platforms and tactical masts.

Integration Guide: Mastering the Wideband Spectrum

1. Strategic LTE & Public Safety Intercepts

In the signal-dense 700-2700 MHz band (crowded with FirstNet and commercial LTE), isolating a target requires surgical directional focus.

• The Precision Advantage: The focused 60-degree beamwidth acts as a directional "spotlight," allowing an operator to isolate a specific cell sector or tactical data link while physically "nulling out" interference from the sides and rear.

2. Tactical Jamming & J/S Ratio Optimization

When projecting power across the microwave frequencies, gain is the most critical factor. The 9 dBi gain acts as an RF magnifying glass, concentrating energy into a focused cone, exponentially increasing your Effective Radiated Power (ERP) to successfully disrupt high-speed data links or cellular triggers.

3. All-Weather SIGINT Monitoring

In coastal or arctic regions, salt spray and ice act as conductors that detune open-air antennas. The Fiberglass Radome ensures that the LPHP-700-2700 maintains a consistent VSWR and gain profile, protecting the high-fidelity welded elements from physical and electrical degradation.

The LPHP-700-2700 is a surgical "all-in-one" tool for the 0.7 to 2.7 GHz spectrum. This range is the operational core of modern digital connectivity, hosting Public Safety FirstNet (700 MHz), global 4G/5G LTE, and S-Band Tactical Data Links. In a battlespace defined by low-power digital bursts and high-speed data hopping, the LPHP-700-2700’s 9 dBi gain and Fiberglass Radome protection provide the fidelity required for mission success in extreme environments.

1. Mastering the LTE & Tactical Landscape

Across the 700–2700 MHz range, radio waves behave with "optical" precision. They do not bend over hills; they travel in strict line-of-sight and reflect sharply off almost any solid surface.

• The Precision Advantage: The focused 60-degree horizontal beamwidth of the LPHP-700-2700 acts as an RF "spotlight." This allows an operator to isolate a specific cell sector or a tactical data link 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 data bursts from distances where standard omnidirectional antennas would see nothing but background static.

2. Defeating Urban Multipath & Polarization Rotation

Microwave and LTE signals 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 mobile devices and 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 LPHP-700-2700 features a mounting arrangement that allows operators to switch between Horizontal and Vertical polarization in seconds. This ensures you can match the orientation of the incoming reflected wave to maintain a high-speed data intercept or clear monitoring.

3. High-Power Jamming & J/S Ratio Optimization

To successfully disrupt a target link (e.g., a 700 MHz public safety net or a 2.6 GHz LTE uplink), you must achieve a superior Jamming-to-Signal (J/S) ratio at the victim’s receiver.

• 250W Continuous Denial: The LPHP-700-2700 acts as a powerful directional "floodlight." Its 9 dBi gain acts as an RF magnifying glass, concentrating 250 Watts of energy into a focused 60-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 sophisticated frequency-hopping hardware.

4. All-Weather Reliability: The Fiberglass Radome Factor

In LTE and S-Band operations, even a thin layer of ice or a coating of salt spray on antenna elements can cause a massive VSWR spike, detuning the antenna and destroying its gain.

• Radome Protection: The Heavy-Duty Fiberglass Radome ensures 100% RF transparency while physically shielding the welded 6063T6 aluminum elements. This prevents "Precipitation Static" (P-Static) and ensures the antenna maintains its 9 dBi precision in arctic, coastal, or tropical monsoon environments.
• Low Wind Profile: The tapered, aerodynamic design reduces wind loading on high-altitude towers or moving vehicles, ensuring the 60-degree beam remains steady on the target.

Tactical Deployment Checklist

• Cable Integrity at 2.7 GHz: At 2700 MHz (2.7 GHz), cable loss is extreme. Do not use standard RG-58. Use high-grade LMR-400 or LMR-600. Every 3 dB of cable loss effectively cuts your 250W jamming power or reception sensitivity in half.
• Connector Care: The DIN-Female termination is a professional-grade connector designed for high power and low loss. Ensure it is properly torqued and weather-sealed with vulcanizing tape to maintain the 2.5:1 VSWR.
• Rear-Mount Advantage: Since the mount is at the rear of the 450mm boom, the 2-inch metal mast remains completely behind the antenna. This prevents "Mast Shadowing," which would otherwise cause dangerous reflections and distort the high-frequency beam.
• Boresight Alignment: Because the beamwidth is only 60 degrees, a 30-degree error in alignment will drop your gain significantly. Use a high-quality compass or GPS-aligned mount to ensure the antenna is pointed exactly at the target sector.
