 Model LPHP-400-3000 400-3000MHz 7-9dBi Gain 


Design Features: The LPHP-400-3000 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 400 to 3000 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 viceversa. 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 log periodic dipole antenna is supplied complete in assembled condition. The LPHP-400-3000 assembled log periodic antennas outer-most dimensions are 0.60 meter (24 Inches) long and 0.38 meter (15 Inches) wide. The log periodic antenna operates at D.C. ground with low resistance discharge path for protection against lightning and immunity to noise. The coaxial cable sealed inside the support boom to make it weatherproof. 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. The antenna can be supplied with radome/housing (optionally).
