Yes, it can be recovered and I showed how years ago. Roy
and Tom rejected that approach and instead reverted to
measuring the phase of the standing wave current which
is known to contain zero phase information. Go figure.

Seriously, I showed those two how to calculate the
phase shift in a 1/2WL thin-wire dipole using an
arc-cos function. They responded with a personal
attack. It's all on Google.

If you will check my past postings on Google, you will
find me saying, if the current at the base of the coil
is one amp, we can estimate the phase shift through the
coil by arc-cos(It) where It is the current out of the
top of the coil. That is admittedly a very rough estimate
since the coil distorts the current away from a perfect
cosine envelope but it is closer than measuring the
phase of a signal whose phase is known to be unchanging.
