The LP-300-3000 is a professional-grade, ultra-wideband directional antenna engineered for the 300–3000 MHz spectrum. This Log Periodic Dipole Array (LPDA) provides a unified solution for high-frequency monitoring, tactical jamming, and multi-band communication. By delivering consistent gain across a massive 2.7 GHz bandwidth, it eliminates the need for multiple narrowband antennas, streamlining spectrum surveillance and electronic warfare (EW) operations.
Ultra-Wideband Directivity
The LP-300-3000 offers exceptional frequency agility, maintaining a typical 9 dBi gain across its entire operating range. Its high-efficiency design avoids "loading" techniques, ensuring maximum signal radiation without internal loss. With a 16 dB Front-to-Back ratio, the antenna effectively isolates desired signals from rearward noise and interference. The 60° horizontal and 50° vertical beam-widths provide a focused sectoral footprint, making it highly effective for identifying and monitoring signals in a congested RF environment.
Industrial-Grade Mechanical Hardening
Built for survival in punishing environments, the antenna is constructed from 6063T6 architectural-grade anodized aluminum alloy. The structural design features extra spacers between the dual square-tube support booms to enhance torque resistance and overall durability. For protection against corrosive coastal air and acid rain, the complete array is finished with a robust powder coating. All fasteners, including screws, nuts, and bolts, are manufactured from Type 316 marine-grade stainless steel, ensuring long-term structural integrity in high-salinity theaters.
Operational and Tactical Efficiency
The LP-300-3000 is a "set-and-forget" asset designed for rapid deployment. It is supplied in a completely assembled condition, allowing for immediate installation without field tuning. For tactical flexibility, the mounting bracket is welded at the back end of the booms, enabling operators to switch between Horizontal and Vertical polarization in seconds. To ensure electrical longevity, the coaxial feed line is strategically sealed inside the support boom, protecting the cable from moisture and UV degradation, while a direct D.C. ground path provides immutable lightning protection.

Design Features: The LP-300-3000 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 300 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 vice-versa. 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.
