Coverage tells you where a pad talks. The other Analysis tools answer narrower questions: can these two sites hear each other, can a named place hear Command, and how much of this road is still in.
Site to site
A link is two-way. Pick Site A and Site B (they have to be different), confirm the band, and run it. The reported margin is the worse of the two directions, because a repeater pair is not useful if only one hop works. Results open in a Link workspace above the map: a color rating, an elevation profile, a path mini-map, and the numbers. Receive power is the headline; the tables underneath are for when you need to argue about a ridge. Heading A→B and B→A sit under Distance: the bold number is magnetic (aim a yagi with a compass). The true number in parentheses matches a phone compass set to True North. Under Performance, Parameters lists who ran it and the radio settings used (power, gains, feedline, reliability, land cover) so a saved result still matches that run after a site card changes.
Ratings are meant to be spoken out loud. Excellent is fade well above the planning target with a full Fresnel. Good meets the target with decent Fresnel clearance. Fair meets the target but the path is cluttered or diffracted. Marginal — usable is still above threshold but short of the comfort fade — expect copy, not a fat circuit. Blocked is below threshold. The pill uses fade and Fresnel over ground and buildings. Trees are a loss in the fade, not a dirt wall in the 60% Fresnel test. Line of sight is the same ground ray. Scroll the profile to zoom distance; height zooms at half that rate so a ridge grows a little without flattening. Drag to pan any direction; names stay in the header above the plot. Hover the chart and a marker follows on the mini-map, and the other way around. The path line on the mini-map sits on top of the other overlays.
On the elevation profile, the white band is the 1st Fresnel zone in the air above the ground; the dashed inner stroke is 0.6 F1 (the same 60% clearance used for Good vs obstructed). It does not paint through the hill. The straight ray is geometric line-of-sight (green clear, red blocked). When that ray clips terrain, a dashed green polyline over the ridge tip(s) is the diffraction path — knife-edge geometry, not a second Fresnel ellipse. Diffraction loss still shows in the results table either way.
One named point
Point check is the tool for “will they hear Command from the helibase?” Pick the transmitter, name the pin, and either drop it on the map or type coordinates. You get a one-way path to that exact ground point without painting a whole county. Buildings and large metal shells near the pin can change the answer; the profile will show them when they matter. The pin only stays on the main map while that result is loaded. Same Link workspace, same ratings, plus a tight mini-coverage around the pin so rooftop shadows are visible. You can minimize the progress dialog and keep using the map while it runs.
A road or a travel route
Route coverage is for linear features. Choose the site, draw the path crews actually drive or walk, and analyze. The map paints a 200 ft ribbon under the line colored by link margin (same scale as coverage maps). You get a percent of the route that still has usable margin. Save it if you want it tomorrow. After a run, Export route builds a letter-size summary with a snapshot of the current view.
That is radio along a line, not a truck path to the pad. For a drive, tap the car icon on the site card — see Driving to a site.
