"What did they call the teens to 20's antenna that had multiple feeds
coming
down from one end of the flatop to the other?"
Both the "T" and the fanned inverted L were popular on 200m in 1910-1920
just as the single-wire Inverted L is today on 160m. Back then, ops were
obsessed with maximum antenna current but radiation resistance didn’t enter
into the discussions until the mid '20s. By the mid 20s when CW took over,
much less attention was paid to antenna current as a station performance
metric.
During the spark era, ops would keep adding horizontal wires to the flat top
fans until the line current reached diminishing returns. We typically see
5-6 wires wide-spread in old station photos. Then, separate wires would
connect to the flat top and extended down a common point where it became a
single-wire feeder.
