Do you have a source for this info?
If you spring $30-$50 for an omnidirectional TV antenna you can hang it in a close closet or attic. I had the same problems with the rabbit ears (40 miles from towers.)So I bought a DB4 from Antennas Direct or Channel Master and now get 2x the channels. It is made for roof mount but is hidden away and works well.
