LP-20-500L log periodic dipole antenna manufactured by Antenna experts are 100% in compliance with MIL-STD-810G parameters. Antenna Experts antenna systems provides passive log periodic antenna in compact, versatile form factors that provide extreme wideband performance. This tactical LP-20-500L log periodic antenna uses loading technique to reduce the overall size of array. The shipping length of antenna is 2.6 meters (8.3) feet making it highly suitable for mobile and tactical applications.
The LP-20-500L tactical 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 20-500 MHz bands. The complete tactical log periodic antenna is supplied with powder coating to protect it further from severe environmental conditions. The extra spacers are used between the support booms to improve mechanical durability of tactical log periodic antenna.
The specially designed mounting arrangement of log periodic antenna results in fast installation. The tactical LP antenna can be assembled in less than 10 minutes. This tactical log periodic dipole antenna system is particular suitable for transmission, reception, monitoring, scanning and jamming applications due to its broad band design feature, and small size.
The LP-20-500L assembled log periodic antennas has removable elements, making it highly suitable for easy of shipping/carrying/transportation and handling. All elements of log periodic antenna are supplied in two segments for easy of shipping and handling. The elements are attached via stainless fastener systems at points along the boom. The log periodic antenna operates at D.C. ground with low resistance discharge path for protection against lightning and immunity to noise. All the screws, nuts and bolts of log periodic dipole antenna are made of stainless steel.
Our military grade LP-20-500L log periodic antenna is ideal for spectrum monitoring, surveillance, jamming and EMC applications due to its wide band design features. Our LP series 20-500MHz dual polarized log periodic antenna generates high electric fields required for radiated immunity and emissions EMC test measurements, and features high gain, low VSWR, high power handling, broadband range, and a robust mechanical design. The extra spacers are used between the support booms to improve mechanical durability of log periodic antenna.
Our LP-20-500L log periodic antennas are fully tested to the required specifications using a comprehensive range of calibrated test equipments. Radiation patterns, gain measurements and Antenna Factor are measured on our open area test site. Our Log Periodic Antennas enable transmission/reception, or both, of RF signals simultaneously in two orthogonal polarizations. Our LP series log periodic antennas are great for use in RF spectrum analysis, Ideal for Interference detection and surveillance application. Our horn antennas provide excellent isolation between two ports. Our log periodic dipole antennas can be used to obtain Circular Polarized operation with a suitable hybrid coupler.
Heavy duty log periodic dipole antennas model LP-20-500L manufactured by Antenna Experts are particular suitable for Signal Intelligence SIGINT application, Communication Intelligence COMINT application, Electronics Intelligence ELINT application, Electronic Warfare EW application, surveillance application, RCIED jamming, transmission, reception, spectrum monitoring and scanning applications. The dual polarized log periodic dipole array operates at D.C. ground with low resistance discharge path for protection against lightning and for immunity to noise. The log periodic antenna can be supplied with customized mounting hardware. All our log periodic antenna can be supplied with Antenna factor AF chart on request.
