Broadband Log-Periodic Directional Antenna 800–1300 MHz 9.5 dBi 50 Ohm N-Female Aluminum Alloy
The Broadband Log-Periodic Directional Antenna (800–1300 MHz) is a high-quality, wideband antenna designed for stable reception and transmission of radio signals within the UHF and lower L-band spectrum. Featuring a log-periodic array structure, this antenna ensures consistent performance across a broad frequency range, making it ideal for measurement, telemetry, and wireless communication applications.
Constructed from lightweight aluminum alloy, the antenna uses two precision-stamped metal elements with multiple rod-shaped vibrators attached along a guiding spine. The elements are separated by RF-transparent spacers, ensuring mechanical rigidity and consistent electrical properties. The output is a 50-Ohm coaxial cable with an N-female connector, allowing reliable integration into professional RF systems.
The log-periodic directional design provides stable gain and smooth impedance characteristics over the entire operating band (800–1300 MHz). With a gain of at least 9.5 dBi and a beamwidth of 46–75°, this antenna maintains strong, focused reception and transmission capabilities while minimizing side lobes and interference.
Designed for easy installation, the mounting bracket allows secure attachment to any vertical mast up to 50 mm in diameter. Its weather-resistant aluminum construction ensures long-lasting performance even under variable environmental conditions.
