There were antennas in cars that attached to the chicken wire that was
already in the cloth top. When all steel bodies came out in 35 antennas were
mounted under running boards and even using the trim ring of rear mounted
spare tires.
When the cowl mounted whip appeared in the late 30's reception was much
improved.
I had the fairly common 9' rear bumper mount whip on several late 40's and
50's cars once I quit mobile ham use. Sure picked up more stations.
