An RF channel on TV is the old VHF system. Those channels range between 2 and 13 while the RF UHF stations broadcast on channels 14 to 51. Your antenna has to be designed for both systems if you want to watch all those channels.

To learn more about this topic, just continue to read our article. It has the information you want to know about so you can find the right antenna for your RV or trailer. Not everyone uses the satellite system just yet.

What Are RF Channels on a TV?

The RF in this topic stands for radio frequency. That means that different broadcast stations send out their television programming on a specific frequency. There may be more television stations in each category than listed above.

VHF is part of the RF system and it stands for very high frequency and UHF, another part of the RF system stands for ultra high frequency. Many older television sets could not get UHF stations as their antennas were only designed to pick up VHF signals.

The old VHF system was where all the analog stations were broadcast. Their frequencies fell in between these ranges- 54-88 Mhz for channels 2-6, and 174-216 Mhz for channels 7-13.

The newer digital frequencies are all broadcast on the UHF system today. Their frequencies fell or fall between this range- 470-698 Mhz UHF channels 14-64.

Instead of finding channel 3 for the old VHF option, you now may have to look for 3.1 on the UHF side of broadcasting. To find any of these channels, you need a VHF-designed antenna for the VHF channels and a UHF-designed antenna to pick up the digital signals used today.

How do I Watch RF Channels on My RV TV?

When you are not in a campground that does not offer any cable hook-up services or you do not own a satellite dish, then you need a good antenna. RF would be the wrong letters to use here.

RF stands for radio frequencies and both the analog and digital broadcast system use radio frequencies to get their signal to your TV. What you need to look for is an antenna that picks up the different signals.

By that we mean you need a VFH antenna to pick up the old analog broadcast signals and you need a UHF-designed antenna to pick up the new digital television signals.

Or, you can find and buy an antenna that picks you both signal ranges and broaden your TV viewing time. Anyone of the three options will handle the RF portion of television viewing.

All TV signals go through what is called the ether using Radio Frequency electromagnetic waves. You do not need a special antenna to pick up these signals. A regular UHF antenna will pick up all the new digital TV signals.

RF Channel vs Found

The title of this section may be a little confusing. Basically, the RF channel is the channel you can pick up without any problem with your antenna. When the system says ‘found’ that should be the only channel you can watch through your system.

If you are getting nothing but snow on your screen, then that means your antenna has not found any signals in the area or it is not designed to pick up those signals that are in the area.

There are many reasons why you can’t pick up any signals. One is you are camped in a very remote location or and another is that there are too many obstacles in your antenna’s way.

Or you are not using shielded cables. Unshielded cables can pick up a lot of interference stopping them from transmitting the signal from the antenna to your TV set.

As a side note, we came across an interesting little tidbit during our research. There is a YouTube RV channel called RVerTV click the name to go to their website.

This television station has videos and streaming options to help you have a great night of TV watching. The subscription link takes you to their YouTube channel and it may be worth watching if you are a newbie RVer.

TV Only Finds RF Channels

Well, all TV antennas should be finding TV stations marked RF. That RF as explained earlier simply means radio frequency. All analog and digital broadcast signals use the RF range.

It will be up to your antenna whether you get RF VHF analog signals or RF UHF digital signals. According to Samsung, if you are only getting RF channels 2 to 13, then your RF cable is attached to the wrong input jack on your television set.

All you have to do is move the cable from its current location to the other input jack. Then everything should be fine. If you are missing channels, then you may have to run your auto-programming feature to see if it will pick up those missing channels.

If you are still not getting all the channels, connect the RF cable to another TV set, if you can. If the problem persists, then there is a problem with the cable or the antenna.

Some Final Words

Picking up television signals in your area depends on several things. One, if you own a satellite dish, you just need to point the dish to the right satellite. Two, if you have a cable hook-up, then you just need to have the right cable to make the connection.

Three, if you are only using a regular television antenna, then you need to make sure it can pick up all RF VHF and UHF signals to get full television coverage. Check your antenna first before doing anything else. That may solve all your entertainment problems.

RF Antenna input is typically used to connect a television antenna, cable TV wire, or satellite feed to a television, VCR, or other device that can process radio-frequency video signals, including some computers. Knowing when to use an RF signal and how it differs from other signals can be useful when setting up some computer and video systems.

A radio frequency (RF) signal is an electrical signal emitted as a radio wave. It travels from the broadcasting antenna to the receiving antenna. Different channels carry the signal at different frequencies. Depending on conditions, the signal can be received as far as 80 miles from the broadcast antenna. An RF signal can also be carried on wires that have been configured appropriately, either from a nearby broadcast antenna or as part of a cable TV distribution system serving an area ranging from a building to a city.

The most common RF input resembles a short, thick bolt about one-quarter inch in diameter and one-quarter inch long. The cable cord screws into the bolt. Older television sets may have two screws side by side, designed to attach wires from a cable called a twin lead. There is an electrical difference between the two forms of connector. An adapter may be required to attach twin lead wires to a round RF input or vice versa. The adapters are inexpensive and widely available.

A television image encoded as an RF signal contains audio and video, both of which are decoded using a tuner. The key difference between a monitor and a television set is that a monitor cannot process an RF signal directly. Most televisions, VCRs, and cable TV boxes let you output the decoded audio and video signal to other devices. Separating the video and audio signals gives better quality than the integrated RF signal; S-video, component video, and HDMI outputs offer higher quality than RF. For a computer to process RF signals it must have a video card equipped with an RF input plug, as well as other hardware and channel-selecting software.

Using an RF signal to carry audio and video from one device to another is an option of last resort, as it is always the lowest-quality option. However, with older television sets and VCRs, or in complex setups, RF may the only option available. Most VCRs, legacy game consoles, satellite receivers, and cable descramblers can accommodate an RF signal, typically on channel 3. External RF modulators are available to generate an RF signal from the video and audio outputs widely used on computers and audio-video devices.

RF signals are used for FM radio signals and Wi-Fi computer networks. FM radios and audio/video receivers may have an RF input for the radio antenna, or a connection for a cable system carrying FM radio signals. Wi-Fi antennas usually connect directly to the wireless transmitter.
