Antenna Experts manufactured world’s highest performance military grade log periodic antenna. 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.

Antenna Experts offer a wide range of log periodic antennas covering the HF, VHF, UHF and microwave frequency bands for defense/military monitoring, scanning, receiving, signal intelligence (SIGINT), jamming and transmitting application. Apart from the list appeared above, we are experts to develop antenna with any frequency band. The LP series ranges of log periodic dipole array are high gain array that provides strong performance over the operating frequency range of 20 MHz to 6000 MHz. as the log periodic dipole array does not use loading technique to reduce the overall size of array.

The LP series log periodic antennas features high power handing capabilities, high efficiency, low VSWR and robust mechanical design to accommodate the most extreme environments condition. The defense log periodic antenna supplied with powder coating finish to protect the antenna further from severe environmental conditions.

The LP series MIL-STD log periodic dipole antennas use 6063T6 ultra corrosion resistant architectural anodized aluminum alloy and designed to provide wideband directional transmission/reception of radio signals for the specified frequency band. The specially designed mounting arrangement of LP antenna results in fast installation. The extra spacers are used between the support booms to improve mechanical durability of log periodic dipole antenna.

Log periodic dipole antenna can be assembled in less than 10 minutes. This log periodic dipole antenna system is particular suitable for transmission, reception, monitoring, scanning and jamming applications due to its broad band design feature. This high gain LPA provides strong performance over the entire specified frequency band as the LPDA does not use loading technique to reduce the overall size of array.

Most of the LP series log periodic antenna has removable elements, making these LP antennas highly suitable for easy of shipping/carrying/transportation and handling. All elements are supplied in two segments for easy of shipping and handling. The elements are attached via stainless steel nuts & bolts systems at points along the boom. The UHF log periodic antenna are supplied complete in assembled condition.

The powder coating on complete log periodic dipole antennas surfaces ensures complete protection from corrosive gases, ultraviolet radiation, salt spray, acid rain and sand storms in desert environments also provides extra protection against corrosion in saline weather present in coastal areas. The coaxial cable of log periodic dipole antennas sealed inside the support boom to make it weatherproof.

The log periodic dipole antenna operates at D.C. ground with low resistance discharge path for protection against lightning and for immunity to noise. All screws, nuts and bolts of log periodic dipole antenna are made of type 316 marine grade stainless steel. Log periodic dipole antenna above 300MHz are supplied complete in assembled conditions. Optionally these UHF log periodic antenna can be supplied with radome/housing.

The LP-20-3000L tactical log periodic dipole antenna is small size log periodic antenna and designed to provide wideband directional transmission/reception of radio signals from 20-3000 MHz bands. The compact size of tactical log periodic antenna is supplied with powder coating to protect it further from severe environmental conditions. The specially designed mounting arrangement results in fast installation. The compact size tactical LP antenna can be assembled in less than 10 minutes. 

This compact size tactical log periodic dipole antenna system is 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 compact size tactical log periodic antenna uses loading technique to reduce the overall size of array. The shipping length of antenna is 6 feet making it highly suitable for mobile and tactical applications. 

The LP-400-6000 high performance log periodic dipole antenna uses 6063T6 ultra corrosion resistant architectural anodized aluminium alloy with welded elements. The complete antenna is supplied with powder coating finish to protect it further from severe environment conditions.  The high gain LP–400-6000 log periodic dipole antenna is designed to provide wideband directional transmission/reception of radio signals from 400 to 6000MHz bands. The high-performance high gain log periodic dipole antenna is supplied complete in assembled condition.

The LP-400-6000 assembled high gain log periodic antennas outer-most dimensions are 650mm long (radome) and 380mm wide. All elements of high gain LP-400-6000 high performance log periodic antenna are fully welded to its support boom to prevent RF inter-modulation and antenna is completely protected within a high-tech ruggedized radome which is made of fiberglass to ensure survivability in the worst environments conditions. The heavy duty fiberglass enclosure has excellent transparency for RF signals and enough strength to withstand more than specified wind loads.

The LP-100-1000 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 100-1000 MHz bands. The specially designed mounting arrangement results in fast installation. The extra spacers are used between the support booms to improve mechanical durability of antenna.

This LP-100-1000 log periodic dipole antenna system is particular suitable for transmission, reception, monitoring, surveillance, scanning and jamming applications due to its broad band design feature. This high gain LPA provides strong performance over the entire frequency of 100-1000 MHz as the LPDA does not use loading technique to reduce the overall size of array.

The LP-100-1000 assembled log periodic antennas outer-most dimensions are 1.8 meters (71 Inches) long and 1.5 meters (60 Inches) wide. The antenna has foldable elements, the longest of which is 0.75 meter. All the elements are supplied in two segments for easy of shipping and handling. The elements are attached via a stainless steel stud system which is fixed at each element end for attaching the same on the corresponding marked position on support boom. 

The log periodic antenna operates at D.C. ground with low resistance discharge path for protection against lightning and immunity to noise. The complete antenna is supplied with epoxy based powder coating finish to protect it further from severe environmental conditions.

The LP-80-2000 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 80-2000 MHz bands. The specially designed mounting arrangement results in fast installation. The extra spacers are used between the support booms to improve mechanical durability of antenna. 

This log periodic dipole antenna system is particular suitable for transmission, reception, monitoring, surveillance, scanning and jamming applications due to its broad band design feature. This high gain LPA provides strong performance over the entire frequency of 80-2000 MHz as the LPDA does not use loading technique to reduce the overall size of array.
