What does RF CH mean?


What is the difference between a RF channel and a virtual channel? The RF channel is the channel that the TV station uses to broadcast its signal. Before the conversion to digital, TV stations were normally identified by their channel number, and most people knew that a particular network was on a specific TV channel. While analog broadcasting was being phased out and all TV stations were converting to digital broadcasting, it was necessary for the TV stations to continue to broadcast their analog signals on their original RF channels, and also broadcast their digital signals on a different RF channel. However, since the TV station used their broadcast channel as part of their identification, they wanted to keep using the same channel number. To allow this to happen, the new digital television broadcasting standards (ATSC) provided TV stations the ability to continue to use their original channel number and also tell the TV set to tune to the new RF broadcast channel when their virtual channel number was selected. The original channel number is called the virtual channel number, and it will be followed by a period and a second number (3.1, 7.1, etc.).
One of the benefits of converting to digital for the TV stations is that they now have the ability to transmit more than one program at the same time on the same RF channel. The number of additional channels they can broadcast is determined by the resolution of the program (SD vs. HD, text only, music only, etc.). The second number in their virtual channel number indicates that one of the additional programming sources from the same TV station is being viewed (10.2, 10.3, 10.4, etc.).
When selecting an antenna, it is important to understand the difference between the RF broadcast channel and the virtual channel. Antennas are designed to receive specific ranges of RF channels, and the antenna needs to be selected for the RF channel you wish to receive. TV stations broadcast in two broad frequency ranges, called VHF and UHF. RF channels 2 through 13 are considered VHF, and RF channels 14 through 51 are considered UHF. In order to pick up the channels, the antenna has to be designed for the correct frequency range. It is very common today to find that TV stations using virtual channels 2 through 13 are actually using RF broadcast channels in the UHF range. Although not as common, some TV stations using virtual channels 14 through 51 are actually transmitting in the VHF range. An antenna designed for only UHF channels will not work effectively for RF broadcast channels in the VHF range, and an antenna designed for only VHF channels will not work effectively for RF broadcast channels in the UHF range.

Just bought a digital antenna and can only get 3 channels what can i do to correct this problem


Is the antenna mounted on an inside wall?
Or, is it mounted on an outside wall, and cabled through an exterior wall, and connected to your TV?
Where do you live -- maybe, there are only 3 over-the-air stations near you?
There are web-sites that show the location of the stations' broadcast-towers. If your TV is on the "opposite" side of your home from those towers, your home is blocking the signals. Move the TV, and try again.

I can't get FOX on my converter box--what is the channel # for FOX?


It could be your antenna. Some retailers sold consumers UHF-only outdoor antennas and not VHF/UHF combo antennas. Other outdoor antennas may not have a power boost included for the VHF antennas (rabbit ears). The new DTV signals from stations are now broadcasting in lower power signals than before June 12.

Outdoor Antenna


KMSP/FOX 9 and KARE 11 both broadcast on VHF signals. WCCO and KSTP broadcast on UHF signals. You will need a VHF/UHF outdoor antenna to pick up KMSP and KARE 11 and also get all the other channels.

Indoor Antenna


Check your antenna to make sure it's a UHF/VHF antenna. You may need an indoor antenna that has rabbit ears -- that is the best way to get KMSP/FOX 9 reception on your TV. Your antenna should have a power boost to amplify the VHF signal if you are having trouble getting FOX 9 or KARE 11.

What Antenna Is Right For You?

Need help locating the proper outdoor antenna to receive your local television broadcast channels? Based on geographical maps and signal strengths, AntennaWeb.org locates the best antenna for you, whether it's a home satellite system, high-definition television (HDTV) or a traditional analog set.

Make sure you antenna is pointed toward Shoreview, where FOX 9 transmits from.

Since the digital switchover, I have lost channels, despite re running the setup and tuning. Any suggestions as to why this is happening?


I have a similar issue. When the digital switch happened here some of the local TV stations changed frequencies from UHF to VHF. I do not have a VHF antenna so I am unable to receive these channels. I do have a great UHF antenna, but it will not receive VHF. The fix is of course is a new UHF/VHF antenna. I am 50 miles away from the TV transmitters.

This may or may not be your problem. I hope this is helpful to you.

Local ABC and PBS stations do not come in. All others local stat


Check to make sure your DTV antenna is an "all band" antenna with reception in both the UHF and VHF bands. It sounds like you may be in Philadelphia area. In Philadelphia, all the DTV stations are in the UHF band except Ch 6 and Ch12, which are in the VHF band. Some of the DTV antennas are UHF only. You can tell if yours can receive VHF if it has the "rabbit ears" long wip antennas. If so make sure the whips are extended fully and turn the antenna to try to get a good signal.

Visit the 6ABC and WHYY websites for up to the minute information about the issues with reception issues.

You may need an antenna that gets VHF and UHF bands. The "rabbit ear" antenna is designed for VHF band. Many of the DTV channels are located in the UHF band. You may want to call the FCC's DTV hotline for help. They will know the TV stations in your area and can tell you if you need a different antenna. The can also arrange for someone to come help set up your DTV converter at no charge to you. 1-888-CALL-FCC is the number.

Antenna for my HDTV


Special HD or Digital antennas are not required to receive digital stations. A good VHF/UHF antenna should work. Try an amplified antenna for the best reception. Most antennas have a coax type connector which should connect to the ant. in jack on the back of your DirectTV box or to your tv depending how the box is connected to your tv.

I bought a 32" conia tv and i cant get good reception! i have bought a amplified antenna and a hd set top box and still no good reception. my other tv's in the smae spot have had no reception issues....


well it's the same as the days of old, the antenna has a range of reception. the further the sations antenna, the lager your antenna must be. just because you bought an amplified antenna does not mean you will receive the deep fringe station. also the antenna must be UHF and VHF to receive the broadcast in digital. most of the braodcasters have gone with the UHF band because it is more stable for the bandwith of digital broadcast. the UHF band is very directional as well, so you must be pointing to the broadcasters antenna. no set top antenna will work if you are further than 15 miles of the broadcasters antenna. the roof top UHF/VHF antenna with a preamp is the way to go. I have tested every compact antenna and unless you live in the city that the broadcast generates you will get no reception with these. terks are junk, and any small amplified antenna does not work if you are in low lying areas. roof top, roof top,.....ROOF TOP!!!!!

Hi there!

Assuming that you tried to tune stations onto the UHF bandwidth and received nothing,Commonly the tuner box is probably at fault and needs replacement. The VHF and UHF signals are split inside the tuner so if you receive VHF fine then UHF should as well unless faulty of course. Some circuits require an external IC to do the switching, but more on the older models. Regards and good luck, JUS004
