If  you construct something in the near field of a broadcast station
directional antenna system, that absorbs / reflects / redirects some of
the transmitted RF energy, then you will distort the antenna pattern and
affect the field strength of the radiated signal.
In the near field, anything affecting the RF field is "seen" by the
transmitting antenna system, and effectively becomes a part of it.

That is just as illegal as going onto the stations  physical property
and modifying the antenna system or damaging the transmitter.

If you are in the far field region, however, then anything you use to
intercept the RF energy will not be directly "seen" by the transmitting
antenna.  In the far field region, the interception antenna t is
effectively decoupled from the transmitter, and generally causes no more
harm than simply tuning a receiver to the transmitted frequency.
