Ultra-Wideband Printed LPA Antenna

The optimized printed Log-Periodic Dipole Array Antenna (LDPA) is designed for RF testing and signal monitoring, providing reliable ultra-wide frequency coverage from 400MHz to 8GHz. Perfect for radio testing and field measurement scenarios.

Key Features:

• Stable RF Performance: Rated 50Ω input impedance matched to standard RF equipment, ensuring consistent performance across bands. Achieves return loss of approx. 10dB or less with a VSWR of around 2 in most bands above 1GHz. In the 400MHz–1GHz band, return loss is about 4.5dB or less with a VSWR of around 4.
• Handheld Radio Direction Finding: Supports general-purpose radio direction finding from 1GHz to 8.5GHz. Provides decent directional sensitivity to signal sources when held single-handedly; simply rotate your body and the antenna to observe signal strength changes and locate the transmitting source.
• Optimized for tinySA ULTRA Spectrum Analyzer: Engineered to pair seamlessly with the tinySA ULTRA spectrum analyzer, transforming your portable test device into a complete mobile RF measurement and direction finding kit. Features a direct plug-and-play connection with its 50Ω impedance.
• Compact Form Factor with Balanced Design: Achieves wideband performance in a compact footprint of 27×23cm. The design prioritizes low-frequency matching and directionality while maintaining portability and RF performance.

Packing List:

Includes one ZA-048 Log-Periodic Dipole Array Antenna set (tinySA ULTRA not included). The adjustable mounting bracket is compatible with 2.8-inch TinySA and 4-inch TinySA Ultra+ models (ZS405 / ZS406 / ZS407), enabling professional RF signal direction finding setups once installed.
