 Model LP-20-1000 20-1000 MHz 9 dBi Gain 


Design Features: The LPL-20-1000 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 20-1000 MHz bands. The complete 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 antenna. The antenna can be assembled in less than 10 minutes by two technicians. This log periodic dipole antenna system is particular suitable for transmission, reception, monitoring, scanning and jamming applications due to its broad band design feature. The shipping length of antenna is 10 feet making it highly suitable for mobile and tactical application. Two mounting brackets are fitted on the support boom one for horizontal polarization and other for vertical polarization.

Constructions: The LP-20-1000 assembled log periodic antennas outer-most dimensions are 6.5 meters (21.3 feet) long and 7.5 meters (24.5 feet) wide. The antenna has removable elements, the longest of which is 3.5 meters. All elements are supplied in two segments for easy of shipping and handling. Similarly the support boom of antenna is supplied in two sections for easy of shipping/transportation and handling. The elements are attached via stainless steel stud systems with spring washer 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 type 316 marine grade stainless steel. Specially designed mounting arrangement results in fast installation. The polarization can be changed from horizontal or vertical and vice-versa.
