I had overlooked them, but these tags definitely have to be dropped.

The ten or so that I checked were pretty close, within 5 metres. One was either very recent, or
20 metres off. (BIPT has location 51.151194,3.235139 but there's no structure visible there on
the most recent imagery.)

In any case, we would get higher quality with a manual review instead of fully relying on the
source: we can correct errors when the structure is visible on imagery.

Such is an import discussion. Original Poster has my appreciation too :)

Looking at the source data, it's going to be one node for one mast, which typically has several
directional antennas mounted on it. A node per antenna is not something I'd like to see either.

Off-topic: when referring to the electrical part, "antennas" is actually the most common form. By the way,
could you maybe start trying to behave more constructive and socially acceptable? I believe you can
do it with some effort.

Kind regards,
