Ultra-Wideband Printed LPA Antenna

The optimized printed Log-Periodic Dipole Array Antenna (LDPA) is designed for RF testing and signal monitoring, offering 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 ensures 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. Offers decent directional sensitivity to signal sources when held single-handedly; simply rotate 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. Plug-and-play compatibility with a matching 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 within size constraints, balancing portability and RF performance effectively.

Packing List:

• ZA-048 Log-Periodic Dipole Array Antenna (1 set)
• Adjustable mounting bracket compatible with 2.8-inch TinySA and 4-inch TinySA Ultra+ models (ZS405 / ZS406 / ZS407).

Once installed, the bracket enables professional RF signal direction finding setups.
