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.
