Antenna TV: If Still Cannot Receive WKAR TV After Rescanning

Jul 9, 2018

WKAR-TV changed its broadcast frequency on May 29, 2018 as required by the FCC. If you're an antenna TV viewer, have rescanned for channels to tune in the new frequency, and are still not able to receive WKAR, here is some information that we hope can help you find WKAR or another PBS station broadcasting in your area.

WKAR-TV Coverage Area

The power level and the coverage pattern for WKAR-TV are essentially the same on new digital frequency 33 as on the previous digital frequency 40. The WKAR tower location has not changed, so distance and direction from your location remain the same as before the frequency change.

WKAR's new frequency and coverage area are assigned and regulated by the FCC. There are no additional changes planned at this time.

What's Different
 
The difference between previous frequency 40 and current frequency 33 is the wavelength of the signal. This difference can affect how the signal bounces off buildings near you (called multipath interference) or passes by obstacles such as tree foliage.

At your location, you may be experiencing interference at digital channel 33 that was not a problem for channel 40.

Additionally, the change in wavelength can uncover problems such as bent, damaged, or missing antenna elements, and poor connections or kinks in your cabling. Higher powered stations may pass through problems like this, while lower powered stations may be blocked.

Here are some areas to investigate. You may need to consult with an antenna TV technician to resolve these issues.

Antennas
We always recommend outdoor antennas, and suggest the website antennaweb.org for antenna selection guidance.

Antenna Location
If you have an indoor antenna, try moving it to a different location in the room.

Attenuator or Signal Filter
Your antenna installation could include an attenuator or signal filter that was effective at eliminating interference on frequency 40, but not the new frequency 33.

Gain Ampilifier
You may have a powered gain amplifier that is boosting interference rather than improving your signal on frequency 33. Try removing the amplifier (or unplugging it) and see if reception improves.

Cabling and Connectors
Your cabling and connectors could be more susceptible to interference at frequency 33 than 40.

Check that your coaxial cabling does not include any loops of excess cable. If you have multiple cable connectors in your cable run, wherever possible run longer lengths of one cable rather than multiple lengths joined with connectors.

The transformer (balun) connecting your antenna to the coaxial able might not be fully connected, or might have been damaged by nearby lightning.

Check each F-connector in your coaxial cabling from antenna to receiver. The center conductor on the F-connector should extend beyond the sleeve slightly and should be cut sharply. Be sure the connection is tight.

Other PBS Alternatives
If you are not able to resolve these issues to receive WKAR-TV, we hope that you can receive another PBS station reaching your area.

Please note that signal strength calculations assume an outdoor antenna 30 feet above ground level. Actual reception quality may vary significantly for viewers using an indoor antenna.   
 
Actual signal strength may vary based on a variety of factors, including, but not limited to, building construction, neighboring buildings and trees, weather, and specific reception hardware. Your signal strength may be significantly lower in extremely hilly areas.
