LOG PERIODIC ANTENNA

Design Features: The LP-200-500 log periodic dipole antenna log periodic dipole antenna uses 6063T6 ultra corrosion resistant architectural anodized aluminum alloy is designed to provide wideband directional radio signals from 200 to 500 MHz frequency band. The extra spacers are used between the support booms to improve mechanical durability of antenna. The mounting bracket is welded at the back end of the dual booms of log periodic antenna which permits to change the polarization from horizontal to vertical and vice-versa. The coaxial cable sealed inside the support boom to make it weatherproof. This log periodic dipole antenna system is particular suitable for transmission, reception or monitoring and jamming application due to its broadband design feature and small size. This log periodic antenna provides strong performance over the entire band. Log periodic antenna does not use loading technique to reduce the overall size of array.

Constructions: The LP-200-500 assembled log periodic antennas outer-most dimensions are 1.4 meters (4.5 feet) long and 0.75 meters (2.45 feet) wide. The antenna has removable elements, the longest of which is 0.36 meter. All elements are supplied in two segments for easy of shipping and handling. The elements are attached via a fast deployment studs & nuts system 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 marine grade stainless steel. Powder coating of the complete log periodic antenna provides extra protection against corrosion in saline weather present in coastal areas.
