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......
