The ARL60R/F80XZ is a directional broadband log-periodic (logarithmic) antenna engineered for radiomonitoring and professional RF measurement activities in the 60–80 MHz VHF low-band. Its directional pattern supports cleaner surveys in challenging RF environments, improving selectivity during interference hunting and providing practical support for direction finding and source localization tasks.

The product is designed for mobile vehicles and fixed monitoring sites, including temporary checkpoints and long-term control centers. Two mechanical configurations are available to match the mission profile: folding elements for fast deployment and transport, or unscrewable elements for structured setups and repeated installations. A standard polarizer solution enables monitoring scenarios where both polarizations must be evaluated within the same campaign.

Typical applications include: spectrum occupancy checks, field-strength surveys, verification of coverage and unwanted emissions, and troubleshooting campaigns in wide-area VHF low-band networks where propagation characteristics can extend operational ranges. The antenna family is used wherever measurement repeatability, documentation and professional reporting are required.

Antenna designed and manufactured in Italy.

Frequently asked questions about ARL60R/F80XZ

Practical answers for selecting and using a 60–80 MHz log-periodic antenna in radiomonitoring, RF surveys and interference hunting activities.

Is the ARL60R/F80XZ suitable for mobile and stationary monitoring?

Yes. It is designed for both use cases, supporting mobile campaigns (vehicles and temporary checkpoints) and fixed monitoring sites where repeatable measurements are required.

What is the difference between folding and unscrewable elements?

Folding elements prioritize speed of deployment and transport, while unscrewable elements are preferred for structured installations and repeated assemblies with defined mechanical setup.

Why choose a directional log-periodic antenna for interference hunting?

Directionality improves selectivity and helps indicate the signal direction, supporting faster localization and cleaner measurements in congested RF environments.

Which services are typically monitored in the 60–80 MHz band?

Depending on national allocations, monitoring may involve VHF low-band two-way radio and related communication services used for wide-area coverage and professional/critical communications.

Do you provide documentation for repeatable measurements?

Yes. A complete manual package is provided, including calibration information, test reports, radiation patterns and K-factor calculation, supporting professional reporting.

What is the recommended approach for installation and maintenance?

Use qualified installers, verify suitability to the installation site, and perform periodic checks. Correct mechanical setup and maintenance help ensure safety and consistent performance over time.
