foot (3 metre) variance in height.
Check the alignment of the Transmitter and Receiver. (Note that if the bolts used for fixing the alignment are

Move the Transmitter and Receiver closer together.
Possible obstructions and other causes of interference.
Water or anything with water in it, including people and other living things, snow, rain etc. can all reduce the
transmission distance.
Metals and anything containing metal—steel-reinforced concrete (rebar), metal window screens and
tool-room cages, aluminum siding and wall insulation foil, even metallic paints, metallic wallpapers and
mirrors will affect the quality of the signal.
Lead windows kill radio transmission, as do windows with a UV protective coating or metallic energy-saving
film.
Other materials such as brick, drywall or wood, also cut down on the signal, depending on their water
content.
High Voltage transmission lines may cause interference to the signal.
AC generators in close proximity to the Transmitter or Receiver may cause interference lines in the picture.
