Model LPDP-30-100 30 - 100 MHz. 5 to 8 dBi. Gain 


Design Features : The LPDP-30-100 dual polarized log periodic antenna is designed to provide wideband directional transmission/reception of horizontal and vertical radio signals from 30-100 MHz bands. The extra spacers are used between the support booms to improve mechanical durability of antenna. The specially designed mounting arrangement results in fast installation. This dual polarized log periodic dipole antenna system is particular suitable for transmission, reception, monitoring, scanning and jamming applications due to its capability of receiving/transmitting the both E & H polarized signals. This high gain LP provides strong performance over the entire frequency of 30-100 MHz as the LPDA does not use loading technique to reduce the overall size of array.

Constructions : The LPDP-30-100 assembled log periodic antennas outer-most dimensions are 3.6 meters (12 feet) long and 5 meters (16.5 feet) width & height. 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 self-locking device 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 stainless steel.
