Operating Instructions:
For best reception, please consider the following
conditions:
1. Keep the antenna away from sources of interference,
including air conditioners, microwave ovens, hair
dryers, etc. These are all sources of strong electrical
interference, and can cause poor quality or total loss of
TV signals.
2. Place the antenna near a window, preferably on the
side of the house facing the TV station transmitters,
when installing the antenna indoors.
3. Install the antenna as high as possible, and preferably
with a clear path between the antenna and the TV
station transmitters. Trees, buildings, mountains, etc.,
can all impact the performance of any antenna.
