PRIVACY & LIMITATIONS

Link parameters stay local. No location or radio is accessed.

Frequency, distance, power, gain, loss, sensitivity, obstacle, and curvature inputs are calculated only on the current page. LinkLine does not request location, maps, terrain, radio interfaces, or device permissions, and it never transmits, scans, or listens for signals.

Idealized path estimate, not a site survey

The tool estimates free-space basic transmission loss as 32.44+20log10(MHz)+20log10(km), combines EIRP, received level, sensitivity margin, and target fade reserve, then estimates first-Fresnel radius and effective-Earth bulge from the obstacle's split distances and k factor. It does not read real terrain or antenna heights or model diffraction, vegetation, buildings, interference, polarization, connectors, rain fade, multipath, throughput, reliability, or local spectrum/power compliance.

Path and equipment values can reveal a deployment plan

The page does not ask for coordinates, addresses, or device serial numbers, and refreshing or closing discards inputs. CSV and reports may contain frequency, distance, EIRP, received level, margin, and clearance needs; optional local checkpoints also save the visible summary. Non-public path lengths, bands, and power budgets may still be sensitive, so review them before sharing.

Advertising and local preferences

This page uses Google AdSense Auto Ads. Google may use cookies or similar technologies under its policies. .miluland.com domain cookies sync language, theme, high contrast, a six-item recent-tools list, and up to 16 favorite tool IDs across MiluLand sites. These values never contain inputs, files, or results; the current site also keeps a local compatibility copy.

Local report studio

The report studio reads only the workbench’s currently visible result summary for local preview, Markdown copy, JSON download, printing, and a SHA-256 fingerprint. It never reads input controls or original files and is not persisted unless you choose to download it.

Optional local checkpoints

Only when you explicitly choose Save does the tool write the visible result summary, time, and optional short label to this site’s browser storage, up to five entries. Imported files and input-control contents are never stored; you can export, restore same-tool checkpoints, or clear them at any time. Imports are limited to 128KB and validate the tool, timestamp, summary, and label of up to 80 characters.
