  1) distance, as signal strength decreases at the rate of inverse cube times distance
  2) any object that block the signal
  3) Ferrous materials, can act as extra antennas, and may, or may not help the signal
  4) Transmitting power

  Signal frequency affects its propagation. Lower frequencies tend to bounce while higher frequencies tend to go through objects.

  Initial power of a signal affects is ability to exhibit the aforementioned properties.

  Ferrous materials too close to the antenna can electrically extend the antenna length, unbalancing the signal.

  Liquids tend to deaden signals.

  High electrical power, arcing electricity, and even high strength signals that are close can affect a signal.
