Observed reach

Evidence basis: unique observed finite-SNR remote paths by antenna within each separate comparison group.

Counts are unique remote paths with usable signal reports within each comparison group. “Heard by both” supplies the path universe for same-path analysis; Vertical-only and Inverted V-only paths remain visible.

Observed distance and direction profile

Evidence basis: all usable paths observed for each antenna in eligible blocks, including paths observed on only one antenna. Receiver/transmitter availability may have changed between antenna periods; this describes collected paths and is not a controlled detection comparison. This is not a radiation pattern, propagation model, or causal conclusion about observed or unobserved distances and directions, and it does not rank antennas universally.

Each remote path contributes once per antenna and exact comparison group. Observation support remains visible, but repeated observations from one endpoint do not inflate the footprint count. Near / local distance is a practical proxy only; propagation mode was not measured.

Observed profile: Vertical’s observed paths were concentrated in Regional (500–1499 km), while Inverted V’s observed paths were concentrated in DX-oriented (3000 km and above) in this run.

Review shared-path distance and direction context

This separate view answers where finite-SNR differences occurred among paths decoded on both antennas.

No observed matched paths are available for distance or azimuth context across 8 comparison groups (TX path · 40 m · WSPR · Public report · WSPRnet; TX path · 40 m · WSPR · Imported spot · Imported file; TX path · 20 m · WSPR · Public report · WSPRnet; TX path · 20 m · WSPR · Imported spot · Imported file; RX path · 40 m · WSPR · Local decode · WSJT-X UDP (direct/local); RX path · 40 m · WSPR · Local decode · WSJT-X log; RX path · 20 m · WSPR · Local decode · WSJT-X UDP (direct/local); RX path · 20 m · WSPR · Local decode · WSJT-X log). Location unavailable remains separate (0 missing, 0 inconsistent). This is not a near-zero path delta.

Review exact paired-row distance and azimuth detail

Distance and azimuth path context

Distance and azimuth describe only the remote paths observed in these matched pairs. Missing location stays visible, and geographic concentration limits how broadly these paths represent other distances or directions.

No matched pairs are available for location views.

Review derived solar context

Derived solar context

Solar elevation and light state are deterministic geometric context derived from UTC timestamps and explicit Maidenhead locator cell centers. They are not captured propagation observations, do not adjust comparison values, and do not establish a cause for an observed difference.

Algorithm: noaa-gml-fractional-year v1; coordinates: maidenhead-cell-center-v1. Daylight begins at 0°, civil twilight at −6°, nautical twilight at −12°, astronomical twilight at −18°; gray line denotes any twilight category.

No eligible matched pairs are available for solar context.

Coverage overlap and repeatability

Observed complementarity counts unique paths that appeared in the recorded evidence. Opportunity-conditioned complementarity separately counts one-sided detections among receivers proven active during both cycles. Neither measures signal strength or becomes a composite antenna score.

Unique observed paths do not prove the other antenna could never reach those endpoints. Repeated block support is descriptive, not an inferential uncertainty statement, reliability probability, or recommendation to retain or remove an antenna.
