Hams typically use long wire type antennas that folks tell me have an impedance of sometimes 1000 ohms etc.
If you have a High Impedance device , like a vacuum tube thats output is at lets say 1700 ohms, why cant you make a transmitter or amplifier with no lc circuit on the output , feed the wire through a shunt like a big cap to block the high voltage dc and have a 1700 ohm antenna 900 ft long (for arguments sake) and just fire it up?
this all assumes single band operation and a coincidence of the length of wire being close to resonant on the desired frequency.
