I believe you are correct. I assume they wanted to have the xmtr closer to the city and they traded the height for more power. It reminds me when WLOA-FM had a rather high tower with a high-gain antenna which had all kinds of holes in their coverage area.
Do you remember when WLOA-FM went on the air witha 3 KW Federal transmitter driving a 10 KW Westinghouse FM amplifier, complete with aircraft-style meters with ultra violet lights? Those were the days when transmitters didn't look like upright freezers. The Federal was the loudest xmtr ever build. The blowers sounded like jet engines.
