Model LP-88-108 88 - 108 MHz 9 dBi Gain 
 

FM BAND ANTENNA

Design Features: The LP-88-108 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 88-108 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 88-108 MHz as the LPDA does not use loading technique to reduce the overall size of array.

Constructions: The LP-88-108 assembled log periodic antennas outer-most dimensions are 2.2 meters (7.2 feet) long and 1.7 meters (5.6 feet) wide. The antenna has foldable elements, the longest of which is 0.85 meter. 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 type 316 grade marine grade stainless steel.
