he LP-210-500 is a compact, high-power Wide Bandwidth Log Periodic Dipole Antenna (LPDA) engineered for directional communication and electronic warfare across the 210–500 MHz UHF spectrum. Despite its small physical footprint, this antenna is built for high-intensity missions, offering a consistent 8 dBi gain and a massive 500W power handling capacity. Designed with a "pure" LPDA architecture to ensure linear performance without frequency-dependent blind spots, the LP-210-500 is an elite choice for tactical monitoring, high-power jamming, and secure ground-to-air communications.
Design: Compact UHF Power & Agility
The LP-210-500 is optimized for operators who require a high-power directional aperture that can be deployed in space-constrained or high-mobility environments.
- Unified 210–500 MHz Coverage: Seamlessly covers the primary military and public safety UHF bands. This single aperture eliminates the need for multiple specialized Yagi antennas, streamlining the tactical RF chain.
- Massive 500W Power Handling: Engineered for continuous-duty Electronic Attack (EA) and signal saturation, this compact array manages up to 500 Watts of RF power—unmatched for an antenna of its size.
- Wide Directional Aperture: With an 80-degree horizontal beamwidth, the antenna provides a generous sector of coverage, making it highly effective for wide-area scanning and tracking of moving assets like aircraft or ground vehicles.
- Polarization Agility: The mounting bracket is welded at the back end of the dual booms, allowing for rapid field-switching between Vertical and Horizontal polarization to match mission requirements.
Construction: Ruggedized & Field-Deployable
Built for 24/7 survivability in extreme environmental theaters, from high-salinity coastal zones to rapid-deployment "jump" operations.
- Aerospace-Grade Materials: Constructed from architectural 6063T6 anodized aluminum alloy with square-tube support booms. Extra spacers between booms provide the structural rigidity needed to withstand severe 210 Km/Hr wind loads.
- Weatherproof Signal Integrity: The internal coaxial cable is sealed inside the support boom, shielding it from moisture and corrosive gases. The entire assembly is finished with a protective powder coating to resist UV radiation and salt spray.
- Rapid Tactical Setup: Features removable elements and a fast-deployment stud and nut system. At only 0.65 meters long and weighing 3.5 Kgs, it can be transported and assembled by a single operator in minutes.
- D.C. Grounded Safety: The antenna operates at D.C. ground, providing a safe discharge path for lightning and bleeding off static noise, which is critical for high-fidelity signal interception and monitoring.
Technical Features
- Consistent 8 dBi Gain: Maintains linear gain and predictable radiation patterns across the entire 290 MHz bandwidth.
- No Loading Techniques: Uses full-sized architecture to ensure maximum electrical efficiency and structural durability.
- Superior 15 dB Front-to-Back Ratio: Provides necessary isolation to protect friendly systems behind the antenna during high-power operations.
- Optimized VSWR: Precision-tuned to maintain a stable VSWR of 1.8:1 or better, ensuring maximum power transfer and transmitter safety.
- Rear-End Mounting: Mounting clamps are positioned at the rear of the boom to ensure the mounting mast does not distort the radiation pattern.
EW, SIGINT & Monitoring Compatibility
The LP-210-500 is an elite force multiplier for specialized electromagnetic operations:
- Electronic Warfare (EW): The 500W rating and 8 dBi gain enable surgical, high-intensity jamming of adversary tactical radios, data links, and aero-band communications.
- Signals Intelligence (SIGINT): The directional pattern and clean noise floor allow for accurate Line-of-Bearing (LOB) acquisition for emitter location and signal triangulation.
- Spectrum Surveillance: The wide 80-degree beam is ideal for sector surveillance, allowing operators to monitor a large tactical window with significant gain.
Design Features The LP-210-500 log periodic dipole antenna is a broadband, compact directional antenna, providing continuous communications coverage across the spectrum of 210-500 MHz. The LP-210-500 LP antenna applications include rapid deployment of emergency low-UHF communications, military LOS and SATCOM operations, frequency hopping and jamming sources, spectrum monitoring and management, surveillance, radio scanners, global and wide area SCADA systems and metrology. The LP-210-500 antenna can be used to establish an immediate field command and control center after any natural disaster, where the communications infrastructure has been disrupted, or use it for frequency agile, or wideband Spread Spectrum tactical military traffic, or use it with your Ham Radio or commercial gear to operate on 220 and 406-512 MHz, or more than one channel simultaneously. This high gain LPA provides strong performance over the entire frequency of 210-500 MHz as the LPDA does not use loading technique to reduce the overall size of array.
