General coverage lens
Prioritizes shared-path signal, common listening opportunities, observed reach, distance and bearing, and repeatability. No universal antenna winner is selected.
The goal changes presentation priority only; evidence and calculations are unchanged.
Shared-path signal, controlled detection, and uncontrolled observed paths answer separate questions; none is combined into a broader stronger-results claim.
Controlled common-opportunity detection
UnavailableActivity coverage unknown
Uncontrolled path totals are not substituted for this population.
Population: receivers confirmed active in both cycles of an eligible block for the same comparison condition
Uncontrolled unique observed paths

DX Commander / Attic EFHW · uncontrolled observations
Population: unique recorded remote paths per antenna, whether or not the receiver was active in both cycles

Two rules for reading this Summary
- Missing public evidence is not a zero-strength measurement unless active-receiver evidence establishes a listening opportunity.
- Results describe this recorded run and do not establish a universal antenna ranking.
Shared-path signal
Signed values: Positive values mean DX Commander was stronger; negative values mean Attic EFHW was stronger. The vertical reference is zero.

Each remote path contributes one median regardless of its paired-observation count. Full evidence retains the exact paths, per-path medians, and block-level audit rows.
Observed paths
These are uncontrolled unique-path counts. They do not establish that the same receivers were listening in both antenna cycles, and an observed-only path is not a controlled non-detection.
