Model LP-30-88 30-88 MHz 4~8dBi Gain 
 

LOG PERIODIC DIPOLE ANTENNA

Design Features:The LP-30-88 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 30-88 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 log periodic antenna. The 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 frequency of 30-88 MHz as the LPDA does not use loading technique to reduce the overall size of array.

Constructions:The LP-30-88 assembled log periodic antennas outer-most dimensions are 3.6 meters long and 5 meters wide. The antenna has foldable elements, the longest of which is 2.5 meters. All elements are supplied in two segments for easy of shipping and handling. The elements are attached via a fast deployment stainless steel 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. The complete antenna is supplied with powder coating finish to protect it further from severe environmental conditions All the screws, nuts and bolts of log periodic dipole antenna are made of type 316 marine grade stainless steel. The mounting arrangement of log periodic antenna permits to change the polarization from horizontal to vertical and vice-versa.
