Hi,
    I've been rereading the wiki entry. Is it proposing a structure in
which each transponder is first created as a node labeled
"man_made=communications_transponder" each with all their details. Than
they are grouped as a relation with the
"type=communication_tower_group". Presumably the group could also have
height for the mast and other information?
