Public RF Planner: a simplified planning preview for basic point-to-point checks. Member accounts include the full engineering workspace, advanced propagation tools, detailed Fresnel/terrain analysis, and additional network benefits.

PUBLIC RF PLANNING

Basic RF Link Planner

Choose two locations and run a basic LoRa/Meshtastic path estimate. Sign in as a member for the full engineering workspace and advanced RF analysis.

🔒 Full RF Engineering is available to SKYNET members

The public planner intentionally shows only the basics. Members can use the complete terrain/Fresnel workspace, advanced radio parameters, propagation prediction, detailed link budget, engineering recommendations, and additional SKYNET network tools.

Why SKYNET reached this result

ℹ

Run an analysis to see terrain, Fresnel, diffraction and link-margin factors.

Recommended next actions

ℹ️
Ready for analysis

Choose two endpoints and run the prediction.

Distance—bearing —
Predicted RSSI—after modeled losses
Link Margin—above sensitivity
60% Fresnel—worst clearance
Line of Sight—terrain + curvature
Radio Horizon—A+B antenna horizon

PROPAGATION PREDICTION

Terrain-Aware Coverage Estimate

Coverage is modeled radially from Point A using terrain elevation, Earth curvature, diffraction, antenna configuration, receiver threshold, and configured losses.

Not calculated
Farthest usable—modeled in sampled bearings
Strong samples—≥20 dB margin
Usable samples—≥10 dB margin
Marginal samples—0–9 dB margin
Below threshold—negative margin
Prediction grid—bearings × range samples
Select Point A and click Predict Coverage. Prediction is modeled, not measured RF.

Point-to-Point Terrain & Fresnel Profile

Ground elevation, effective Earth curvature, direct line of sight, and the required 60% Fresnel clearance. The critical obstruction is marked in red.

FRESNEL ANALYSIS

First Fresnel Zone Clearance

SKYNET evaluates the full F1 radius and the commonly used 60% clearance requirement at every terrain sample.

Awaiting analysis
Midpoint F1 Radius—100% first Fresnel radius
Required 60% Radius—midpoint required clearance
Worst 60% Clearance—terrain-to-required boundary
Worst Full F1 Clearance—terrain-to-full F1 boundary
Fresnel Clearance—at worst obstruction
Obstruction Location—distance from Point A
Height Needed—approx. additional path clearance
Fresnel Verdict—engineering assessment
Run RF Analysis to calculate the first Fresnel zone along the path.

Link Budget

Run analysis to calculate path loss.

Engineering Recommendation

SKYNET will evaluate terrain, Fresnel clearance, link margin and antenna height.
