I came across a local AM station that needs revision. The antenna for this AM station consists of four towers that are driven in a phased relationship to create a directional antenna pattern. Currently, only one of the four towers is tagged (with the wrong call letters, which I will fix) and has a FIXME tag saying “which is the primary tower?”. There is no primary tower; they all work together. There is no above-ground connection between the towers.
Is there any sort of relation (or similar construct) that can be used to show that the four towers work together as a single antenna?
For reference, this is at OpenStreetMap
This is a common feature of AM broadcast antennas. Another example I am familiar with is WTAG-AM, at OpenStreetMap
