TYPICAL ANALOG RECEPTION PROBLEMS :
Snow This can be described as a faint image that sometimes fades to black
and white. This most often is a sign of weak reception. A solution might involve
raising the antenna higher to clear any nearby obstructions, adjusting the direction
the antenna is pointing, installing an antenna with a higher gain or installing
an amplifier of some type.
Ghosting This is a very
common problem in areas with large buildings, tall trees, hills or valleys.
The signal bounces off of various surfaces and creates multiple images. This
is called "multi-path" to describe the multiple signals that reach
the antenna. In extreme cases, you may see six or more distinct clear images
side by side overlapping each other. The problem can usually be resolved by
installing a more directional antenna or by raising your antenna higher to receive
a more direct signal. It can take a considerable amount of manipulation to.
In some areas, particularly Southwest Knoxville terrain is responsible for significant
Ghosting of the channel 8 signal which is very difficult to tune
out or cancel. Sparkles Sometimes referred to as bright dots in the picture.
Most often, this is interference caused by some type of electrical device. Typically,
a poorly shielded wire or loose connection on an antenna is to blame.
Antennas degrade with age. As the
rivets become loose, elements can move in the wind and cause poor connections.Most
TV reception problems can be improved with a good quality professionally installed
antenna system. Make sure the retailer you choose understands TV antennas as
a product, rather than just an accessory to a satellite dish system. They should
also have the proper test equipment for measuring signal field strength. A little
research up-front can save you from buying the wrong antenna system for your
Q - I Have Some Type of Problem,
Where Do I Start?The WVLT tower is located in North Knoxville on Sharps Ridge
approximately 0.25 miles south of the I-75 / I-275 / I-640 interchange on the
West side of Sharps Gap. Some other local stations antennas are located on Sharps
ridge on the East side of the gap about 1 mile due east of WVLT. For homes close
to the antenna systems, this may create a problem.
The first step to resolve this
should be to answer a few basic questions:
