 When I was in the US Air Force, I was eventually stationed at McChord AFB near Tacoma, WA  after a stint in Spokane.  If I recall 
 correctly, I was just driving into Seattle for some reason other than to view any radio towers when I spotted the KXA-AM 770 
 longwire antenna atop a downtown office building.  KXA was just a 1,000-watt daytimer, but nonetheless it seemed to be a player 
 in the Seattle media market at the time.  I knew transmitting antennas of this nature existed, but I had never seen
 one in action, and I was amazed that the owners of KXA (1) hadn't applied for an FM outlet;  and (2) hadn't built out
 a standard-issue antenna system with at least one fairly tall vertical tower, and maybe even a directional-array to go to
 higher power (directional to protect KXL-750 down in Portland, Ore that boomed right on up to Tacoma at least.
