That doesn't seem correct.  I know my HDTV antenna strength was very poor,
until I put a reflector behind it.  The concrete walls behind the antenna
were definitely causing some interference on the dipoles.

The multi-path interference won't be apparent with a digital broadcast in
the form of ghosting, but destructive interference will weaken your signal
and could cause the picture to drop out if you are already at the threshold.
