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

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......
