Television is broadcast in two different bandwidths. VHF and UHF. VHF stands
for Very High frequency and uses channels 2-13. UHF stands for Ultra High Frequency
and currently uses channels 14-69. WVLT-TV broadcasts on channel 8 (180-186MHz),
which is in the VHF frequency range. Our digital signal WVLT DT is broadcast
on channel 30 (567.25 - 571.75MHz), which is in the UHF range.
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. The channel 8 antenna is
located 1362 feet above the ground. The digital antenna is located 1470 feet
above ground.WVLT DT is operating at the maximum power allowed by the FCC with
24 hour programming.
Theoretically all television signals
are strongest where there is line of sight between the transmitting antenna
and the receiving antenna. Analog TV signals weaken as the distance from the
transmitting antenna increases.When selecting the proper antenna for your home,
there are many variables that need to be considered. BEFORE WE START Most of
todays TV sets, and VCRs, are cable ready, which means they can
pick up off-air channels 2-69, and cable channels 2-100+. The sets have either
an electronic menu-driven switch, or a mechanical switch to choose between "normal"
The difference between the two
settings can cause great confusion. If you are using a regular TV antenna, the
switch must be in the "off-air" position. If you use a VCR with your
TV, the VCR must be set correctly as well.Another common source of confusion
has been with the auto-scan feature on many TV receivers. Auto-scan recognizes
active channels when the set is initially plugged in and turned on. This is
a great feature as long as the receive antenna is oriented in the direction
of the channels you wish to receive. If the signal is of insufficient strength
to auto program then you must turn the antenna in the proper direction,
find the sets instructions and program in or add the desired channel.
Most sets will have a channel set-up; add/delete option in the menu. Enter the
desired channel, using the arrow, or "+/-" keys to highlight the "add"
feature and press set. The channel should then be available as you surf through
If your analog receiver will not
stop on channel 8 or your digital receiver will not stop on channel 30 (8-1)
and hold in place, most likely the receive antenna is set up incorrectly. Antenna
orientation instructions are available from antenna manufacturers or many local
retailers who carry that particular brand. Very good information is also available
CHECK YOUR EQUIPMENT If you are experiencing problems receiving our digital
signal make sure your digital receiver is set up to receive WVLT DT which broadcast
on UHF channel 30 (8-1), you must also make sure nothing in your antenna system
is blocking the signal. If you have any type of amplifier, splitter or distribution
amplifier in your antenna system, look carefully at the frequency range it is
made for. Some accessories sold in the past have a range of 60-450 MHz. The
frequency range is usually printed somewhere on the case. Any item that has
this range will not work for UHF. WVLT DT Channel 30 (8-1) which transmits at
567 MHz. well outside the specs of these amplifiers.
