Not so. With the antenna connected directly to the plate (or through a
DC blocking capacitor) I guarantee you there will be some reflected
power returning back to the plate. Why? Even a perfectly resonant
antenna does not radiate 100% of the power fed to it on each half
cycle. Some power is reflected back from the end of the antenna to the
feed point  (plate of the tube) where it combines with the next half
cycle. Antennas 101.

The only exception would be an infinitely long antenna, and you are
not likely to ever see one of those, especially mobile.  :-) 

However, that reflected power does not contribute to SWR if there is
literally no transmission line. It's just reflected power.
