At 14 MHz with a rx antenna gain of 0 dBd and no transmission line loss,
that would call for an incident field strength of about 78.7 mV/m. Maybe
not impossible for some SW broadcast stations and very good propagation
conditions?

The maximum nighttime skywave fields received in the skip zones of a 50 kW,
non-directional, MW AM broadcast station generally are less than 5 mV/m.

Actually if one were to calculate the Free Space Path Loss for any
Frequency, it becomes trivial to come up with the MAXIMUM Possible
Receive Signal Strength for any distance, from any amount of transmitted
power level.
