Installation Guide

Begin by selecting a stable mounting surface that offers an unobstructed view of the target signal horizon. Attach the antenna using the provided mounting brackets, ensuring the boom is oriented toward the expected signal source. Because the antenna is passive, no power cables are required; simply connect the feed line to your measurement or communication equipment using a standard SMA connector. Perform a quick calibration by measuring the VSWR across the operating band to confirm optimal performance. For outdoor deployments, consider using a weather‑proof radome to protect the PCB from moisture while preserving its electromagnetic properties. The entire installation process can be completed in under fifteen minutes, allowing rapid field readiness.

Performance Details

Extensive laboratory testing demonstrates that the Yosoo Log Periodic Antenna achieves a typical gain of 8 dBi at mid‑band frequencies, with a front‑to‑back ratio exceeding 15 dB, ensuring strong reception of desired signals while suppressing unwanted interference. The antenna’s impedance remains stable across the full frequency range, delivering a VSWR of less than 2:1, which translates to efficient power transfer and minimal reflection loss. Temperature cycling tests from –40 °C to +85 °C confirm that the antenna’s electrical performance remains within specification, making it suitable for harsh field conditions. These performance metrics provide confidence that the antenna will meet the demanding requirements of both commercial and defense applications.

FAQ

What is the advantage of a log periodic design over a simple dipole?

A log periodic antenna provides consistent gain and impedance over a very wide frequency range, whereas a dipole is typically resonant at a single frequency. This makes the log periodic design ideal for applications that require multi‑band operation without swapping antennas.

Can the antenna be used for both transmission and reception?

Yes, the antenna is fully reciprocal, meaning it performs equally well for transmitting and receiving signals across its entire 0.1‑12 GHz bandwidth. This dual‑function capability simplifies system architecture for test equipment and communication rigs.

Is any special calibration required before first use?

While the antenna is calibrated at the factory, it is recommended to perform a quick VSWR sweep with your own equipment to verify that the antenna is operating within the expected parameters in your specific environment. This step ensures optimal performance and helps identify any installation issues.

How does the passive design affect durability?

Because the antenna does not contain active components or power supplies, there are fewer points of failure. The PCB material is resistant to moisture and temperature extremes, and the lack of internal electronics means the antenna can endure rough handling and outdoor exposure with minimal risk of degradation.

What support does Yosoo provide after purchase?

Yosoo offers a dedicated technical support line, detailed installation manuals, and a one‑year warranty covering manufacturing defects. Customers can also access online resources, including firmware updates for compatible measurement devices and application notes for specific use cases.
