Depends upon the concrete/cement .
( Base fed vertical)
Years ago, found after experimenting with out base insulators that
there were definite high RF losses. (resistance went through to earth)

Hi everybody!
A couple thoughts on shunt fed towers...
Depending on what you read on the web, concrete/cement might (or might
not) be somewhat of a conductor. So, could attaching to concrete around
the house be a help as a ground/radial?
Thoughts???
Feeding a tower with NO RADIALS.
It seems it would be possible to feed a tower about halfway up as a
center fed vertical dipole, with no need for radials. In most cases it
would be a very short dipole for Top Band, tho.
Thoughts???
Sometimes weird ideas pop into my head......
