The military and intelligence communities face a difficult challenge - the need to monitor communications over a very wide frequency range without being detected. Present electronic surveillance systems employ multiple antennas that are either large or noisy. ANTENNA EXPERTS antenna systems provides passive antennas in compact, versatile form factors that provide extreme wideband performance.
The LPDP series ranges of dual polarized log periodic dipole array are high gain array that provides strong performance over the operating frequency range of 20 MHz to 3000 MHz. as our dual polarized log periodic dipole antenna does not use loading technique to reduce the overall size of array.
The LPDP series dual polarized log periodic dipole antennas are particular suitable for Signal Intelligence SIGINT application, Electronic Warfare EW application, surveillance application, RCIED jamming, transmission, reception, spectrum monitoring and scanning applications due to its capability of receiving/transmitting both the vertical & horizontal (E & H) polarized signals simultaneously with 2 independently terminations.
Also our LPDP series dual polarized log periodic antenna can be used to generate Left Hand Circular Polarized (LHCP) or Right Hand Circular Polarized (RHCP) signals (field selectable) using 90 Degrees hybrid coupler (not supplied by us). If user connects these two feed lines (both terminations of array) directly to the quadrature hybridís output, the power delivered to each of orthogonal log periodic arrays will be 90 Degrees out of phase just like they came out of quadrature hybrid coupler. As a result of this user can generate switchable left hand or right hand circular polarized signals.
The LPDP series Dual or Cross Polarized LPDA features high power handing capabilities, high efficiency, low VSWR and robust mechanical design to accommodate the most extreme environments condition. 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 LPDP-20-80-500 & LPDP-20-3000L compact size dual polarized log periodic dipole antennas are small size log periodic antenna and designed to provide wideband directional transmission/reception of radio signals from 20-500MHz and 20-3000 MHz bands respectively. The LPDP-20-80-500 & LPDP-20-3000L compact size dual polarized log periodic antennas are supplied with powder coating to protect it further from severe environmental conditions. The specially designed mounting arrangement results in fast installation. The LPDP-20-80-500 & LPDP-20-3000L compact size dual polarized LP antennas can be assembled in less than 10 minutes.
The LPDP-20-80-500 & LPDP-20-3000L compact size dual polarized log periodic dipole antennas system are particular suitable for transmission, reception, monitoring application, surveillance application, signal intelligence application, electronic warfare application scanning application and jamming application due to its broad band design feature, small size and high power handling capacity. This LPDP-20-80-500 & LPDP-20-3000L compact size dual polarized log periodic antennas uses loading technique to reduce the overall size of array. This tactical cross elements compact size dual polarized log periodic dipole antenna systems are particular suitable for spectrum monitoring applications or low power Tx. application due to its broad band design feature, small size and its capability of receiving / transmitting both the E & H polarized signals simultaneously.
