LPHP-500-2500

Overview: LPHP-500-2500 High-Power High-Performance Log Periodic Antenna

The LPHP-500-2500 is an industrial-grade, wideband Log Periodic Dipole Antenna (LPDA) precision-engineered for the 500–2500 MHz spectrum. Delivering a potent 9 dBi gain and a high 650-Watt power handling capacity (upgradable to 1 KW), this directional aperture is a premier solution for high-power jamming, spectrum monitoring, and tactical data links. Encased in a ruggedized fiberglass radome, the LPHP-500-2500 ensures maximum radiation efficiency by utilizing welded elements and 6063T6 architectural aluminum, eliminating RF inter-modulation and maintaining stable performance across the entire 2 GHz bandwidth.

Battlefield Durability & Radome Engineering

Hardened construction designed to survive the most punishing environmental extremes. The LPHP-500-2500 is protected by a high-tech tapered fiberglass radome, specifically designed for low wind loading (200 KMPH rating) and to prevent ice accumulation. All radiating elements are fully welded to the support boom, a critical feature that prevents RF inter-modulation even under high-vibration conditions. Finished in tactical olive green with an additional powder coating, the antenna is fully immune to salt-spray corrosion in coastal theaters and chemical degradation in industrial environments.

Operational Efficiency

Maximum power projection and signal integrity through advanced RF architecture. Efficiency is maximized by using a pure dipole array without lossy size-reduction techniques. Its optimized 65-degree horizontal beamwidth and stable 17 dB Front-to-Back ratio ensure that RF power is concentrated exactly where it is needed—maximizing link distance for data transmission while providing high isolation from rearward interference and background noise. The antenna operates at D.C. ground, providing a direct low-resistance path to protect sensitive transmitters from lightning-induced surges and static noise.

Detailed Technical Features: LPHP-500-2500 High-Power Log Periodic

Key Advantages: LPHP-500-2500 Strategic Superiority

• Inter-Modulation Free Performance: By utilizing a fully welded element architecture, the LPHP-500-2500 eliminates the "diode effect" often found in bolted or riveted antennas. This prevents the generation of unwanted harmonic signals and RF inter-modulation, ensuring ultra-clean transmission even at maximum power levels.
• Ruggedized Radome Protection: The high-strength fiberglass radome acts as a tactical shield, protecting the radiating elements from physical impact, sand abrasion, and corrosive environments. Its tapered profile is specifically engineered to shed water and prevent ice accumulation, which can detune standard unprotected antennas.
• High Power Density: Capable of handling 650 Watts standard (and 1 kW optional), this antenna is designed for high-duty cycle operations. It provides the necessary "punch" for long-range directional jamming and high-capacity data backhauls across the entire 500–2500 MHz window.
• Superior Mechanical Stability: The use of 6063T6 architectural aluminum combined with internal extra spacers between support booms ensures the antenna maintains its electrical boresight. It is rated for extreme wind speeds of 200 Km/Hr, making it suitable for permanent installation on high-altitude towers or coastal masts.
• Direct Ground Safety Suite: The antenna operates at D.C. ground, providing a permanent low-resistance path to the earth. This design choice effectively drains static build-up and protects sensitive transmitter final stages from lightning-induced surges.

Key Benefits: Operational Efficiency

• Unified Wideband Solution: A single LPHP-500-2500 replaces the need for carrying multiple narrowband antennas for UHF, GSM, LTE, and Wi-Fi. This dramatically simplifies logistics, reduces tower wind loading, and lowers overall system costs.
• Zero Performance Degradation: Because the internal array is protected within a high-tech radome, the antenna's VSWR and gain remain stable regardless of environmental moisture, salt fog, or dust, ensuring consistent link reliability.
• "Plug-and-Play" Tactical Deployment: Supplied in a fully assembled condition with an integrated low-loss cable and N-Female termination, the antenna can be mounted and operational in minutes, a critical advantage for rapid-response tactical units.

EW, SIGINT & Monitoring Compatibility: LPHP-500-2500

The LPHP-500-2500 is engineered specifically for the high-intensity requirements of Electronic Warfare and the precision needs of Signals Intelligence. Its wideband architecture allows a single aperture to perform multiple roles across the UHF and Microwave spectrums.

Electronic Warfare (EW) & Signal Denial

• High-Power Jamming Capability: With a standard capacity of 650 Watts (and 1 kW optional), this antenna is a potent source for high-duty cycle jamming. It can surgically saturate enemy frequencies to deny communications, navigation, and data links.
• RCIED Defeat: Optimized for the directional suppression of Radio Controlled Improvised Explosive Devices (RCIEDs) by jamming common trigger frequencies found in the 500–2500 MHz window, including cellular and Wi-Fi bands.
• Counter-UAV Operations: Acts as a high-intensity directional source for jamming rogue drone control links (C2) and video downlinks. Its high gain ensures that jamming energy remains effective at significant standoff distances.
• Inter-Modulation (IM) Suppression: The fully welded element construction is critical for EW. It prevents the generation of unwanted harmonic interference that can "clutter" a friendly jammer's own signal or compromise the location of the jamming unit.

Signals Intelligence (SIGINT) & Collection

• Precision Emitter Triangulation: The directional 9 dBi gain and narrow beamwidth allow SIGINT operators to perform high-accuracy Direction Finding (DF). By rotating the antenna, operators can pinpoint the exact azimuth of rogue or enemy emitters.
• Weak Signal Recovery: The antenna’s clean noise floor and high sensitivity enable the interception of weak, long-range signals that are otherwise lost to background noise on omnidirectional or lower-gain antennas.
• Wideband Spectrum Coverage: Covers the entire spectrum from 500 MHz to 2500 MHz simultaneously. This allows a monitoring system to scan from traditional UHF tactical bands up through GSM, LTE, and 2.4 GHz Wi-Fi frequencies without switching hardware.

Persistent Monitoring & Surveillance

• Tactical "Electronic Tripwire": When integrated into a persistent surveillance system, the LPHP-500-2500 serves as a directional watchdog, monitoring critical corridors, border zones, or coastal waters for unauthorized RF activity.
• Multipath Immunity in Tunnels: The log periodic design is highly effective at maintaining signal integrity in high-reflection environments. It is ideal for monitoring wireless activity in military tunnels, bunkers, and metallic industrial complexes where multi-path interference typically degrades signal quality.
• Discreet Integration: The compact, radome-protected profile and Military Olive Green finish allow for low-visibility installation on mobile surveillance vehicles (van-top or mast-mounted) and camouflaged ground stations.

Target Frequency Compatibility

The LPHP-500-2500 provides high-performance coverage for:

• UAV / Drone Links: 900 MHz, 1.2 GHz, and 2.4 GHz.
• Cellular Networks: GSM 900, DCS 1800, PCS 1900, 3G/UMTS, and 4G LTE.
• Tactical Data: UHF military communication bands.
• Wireless Data: Wi-Fi (800/900/2400 MHz) and Bluetooth.
