It's good that radio telescopes have been mentioned. While considering this issue, you should also take a look at towers with tower:type=communication and tower:construction=dish
I'm not sure if it is sensible to tag a large satellite dish as a "tower" but that is currently an option that has been used occasionally. https://wiki.openstreetmap.org/wiki/Tag:man_made%3Dtower https://wiki.openstreetmap.org/wiki/Key:tower:type https://wiki.openstreetmap.org/wiki/Key:tower:construction https://wiki.openstreetmap.org/wiki/Tag:tower:construction%3Ddish _______________________________________________ Tagging mailing list Tagging@openstreetmap.org https://lists.openstreetmap.org/listinfo/tagging
