Antenna Experts offer a wide range of high gain high power rating HF VHF UHF log periodic antenna for tactical and fixed station application for military monitoring, scanning, receiving, SIGINT, COMINT, ELINT, jamming and transmitting applications. The military and intelligence communities face a difficult challenge which need to monitor communications over a very wide frequency range without being detected. Present electronic surveillance systems available in the market employ multiple antennas that are either large or noisy. Antenna Experts offers its compact size log periodic antenna solution which are 100% passive which means maintenance free life of several years.
LP-100-512 log periodic antenna systems provides passive antennas in compact, versatile form factors that provide extreme wideband performance for surveillance application, signal intelligence SIGINT application, communication Intelligence COMINT application, electronics intelligence ELINT application and electronic warfare EW applications. The LP-100-512 military grade log periodic dipole antenna is high gain LP array that provides strong performance over the entire operating frequency of 100-512MHz as the log periodic antenna does not use loading technique to reduce the overall size of array.
The complete antenna is supplied with powder coating finish to protect it further for severe environmental conditions. The log periodic dipole antenna operates at D.C. ground with low resistance discharge path for protection against lightning and for immunity to noise and are compatible with MIL-STD-810G. The LP-100-512 log periodic antenna can be assembled in less than 10 minutes in the field with simple hand tools.
The high gain high power military grade LP-100-512 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 100-512 MHz bands. All the screws, nuts and bolts of tactical log periodic dipole antenna are made of type 316 marine grade stainless steel which allow end user several years of maintenance free life.
The extra spacers are used between the support booms to improve mechanical durability of LP-100-512 tactical log periodic antenna. The specially designed mounting arrangement results in fast installation. LP-100-512 log periodic dipole antenna systems is particular suitable for transmission, reception, monitoring, scanning and jamming applications due to its broad band design feature, small size and high power handling capacity.
The LP-100-512 log periodic antenna has foldable/removable elements, similarly the support boom of antenna is supplied in two sections for easy of shipping/carrying/transportation and handling. All elements of log periodic antennas are supplied in two segments for easy of shipping and handling. The elements are attached via a fast deployment stainless steel stud system at points along the boom.
