Air TV Does Not Come With an Extension Cord, But You Can Add One

Air TV tuners ship with a coaxial cable that connects to your wall outlet or antenna, but that cable is typically 6 feet long. If your setup requires the tuner to sit farther from your antenna or cable jack, you will need to buy a separate coaxial extension cable — Air TV does not include one in the box.

The tuner itself has no built-in extension feature or wireless capability to reach distant antennas. You are working with a physical cable connection, so distance is limited by the length of cable you provide. Most hardware stores and online retailers sell coaxial extensions in lengths from 10 to 50 feet, and they cost between $10 and $25 depending on length and shielding quality.

Key Takeaways

  • Air TV tuners come with a 6-foot coaxial cable that connects to your antenna or wall jack, and no extension is included.
  • You can purchase a separate coaxial extension cable from any hardware or electronics retailer to reach farther distances.
  • Longer cable runs may pick up signal interference, so use shielded coaxial cable rated for video to maintain picture quality.
  • If your antenna or jack is more than 20 feet away, consider moving the tuner closer or using a powered amplifier to strengthen the signal.

What Cable Type You Need for an Extension

Air TV uses a standard RG-6 coaxial cable connection, the same type used for cable TV and satellite. When you buy an extension, look for RG-6 cable specifically — it is thicker and better shielded than the older RG-59 type, which can degrade signal over longer distances.

The connectors on both ends should be labeled F-type connectors, which are the threaded connectors that screw onto the back of the tuner and your antenna or wall jack. Most extension cables sold at retailers like Home Depot, Lowe's, or Best Buy come with these connectors already attached, so you straightforward screw them in place.

Avoid flat ribbon cables or unshielded cables marketed for general use. They will work physically, but they pick up electrical noise and can cause picture breakup or signal loss, especially if the cable runs near power lines or through walls with electrical wiring.

How Far You Can Extend Without Signal Loss

A quality RG-6 cable can run 50 feet or more without noticeable signal degradation if your antenna signal is strong to begin with. However, if your over-the-air signal is already weak in your area, adding cable length will make it worse. Every 10 feet of cable introduces a small amount of signal loss, which compounds if you are already at the edge of your tuner's receiving range.

If you need to run cable more than 20 feet, test the signal strength before you commit to a long permanent installation. Plug the tuner in at the far end of the cable run and scan for channels. If you lose channels or see pixelation that was not there with the shorter cable, you may need a signal amplifier — a small powered device that boosts the incoming signal before it reaches the tuner. These cost $20 to $40 and plug into a wall outlet.

Installation Steps for Adding an Extension Cable

Disconnect the Air TV tuner from power before you connect or disconnect any cables. Locate the coaxial port on the back of the tuner — it is the round threaded connector labeled "ANT IN" or "Antenna In."

Unscrew the original cable from the tuner by turning it counterclockwise by hand. Do not use pliers or force — hand-tight is the correct tension. Screw one end of the extension cable onto the tuner port, then run the cable to your antenna or wall jack. Screw the other end onto the antenna or jack connector, again using hand-tight tension only.

Plug the tuner back in and scan for channels. If you see the same channels as before, the extension is working correctly. If you lose channels or see new pixelation, the cable run may be too long for your signal strength, and you should consider shortening the run or adding an amplifier.

Common Mistakes When Installing an Extension Cable

The most frequent error is over-tightening the connectors. Coaxial connectors are designed to seal with hand-tight pressure only. Forcing them with a wrench can strip the threads or damage the connector, creating a poor connection that causes signal loss or complete loss of signal. If a connector feels stuck, explore steady hand pressure and turn slowly — do not use tools.

Another mistake is running the coaxial cable alongside power cords or through areas with heavy electrical equipment. Power lines and transformers emit electromagnetic interference that bleeds into unshielded or poorly shielded cable. Keep coaxial cable at least 12 inches away from power cords, and do not bundle them together. If you must cross a power line, do so at a right angle rather than running parallel.

A third error is buying the wrong cable type. Cheap unshielded cables or old RG-59 cable may work for a few feet, but they degrade signal noticeably over longer runs. Spend the extra few dollars on RG-6 cable with proper shielding — it is the standard for video signals and will save you troubleshooting time later.

When to Use an Amplifier Instead of Just an Extension

If your antenna is mounted on a roof or in an attic far from where you want to place the Air TV tuner, a powered amplifier may be a better choice than a very long cable run. An amplifier sits near the antenna, boosts the signal, and then sends it down the cable to the tuner. This approach works better than a 50-foot cable run if your initial signal is weak.

Amplifiers require a power outlet near the antenna, which is not always practical. If your antenna is on a roof, you would need to run power up there as well as the cable. For indoor antennas or antennas in accessible locations, an amplifier is straightforward: plug it in, connect the antenna to its input, and run the output cable to the tuner.

Frequently Asked Questions

Can I use a regular TV cable extension instead of a coaxial cable?

No. TV cables and coaxial cables look similar but are not interchangeable. Coaxial cable is shielded to carry video signals without interference. Regular extension cords are for power only and will not work. You need RG-6 coaxial cable with F-type connectors.

What happens if I use a cable that is too long?

Signal loss increases with cable length. If your cable run is longer than your signal strength can support, you will lose channels, see pixelation, or lose picture entirely. Test the signal at the far end of the cable before you install it permanently. If you lose channels, shorten the run or add an amplifier.

Do I need to ground the coaxial cable?

Grounding is not required for Air TV operation, but it is a safety best practice if your antenna is outdoors or mounted on a roof. A grounding block connects the cable shield to a ground rod or your home's electrical ground. This protects against lightning strikes. Most outdoor antenna installations include grounding — check your antenna documentation.

Can I split the coaxial cable to connect multiple tuners?

Yes, you can use a coaxial splitter to run one antenna to two or more tuners. However, each split reduces signal strength by about 3 to 4 decibels. If your signal is already weak, splitting will make it worse. For two tuners, a powered splitter (which requires a power outlet) is better than a passive splitter because it maintains signal strength.

Where can I buy a coaxial extension cable?

Home Depot, Lowe's, Best Buy, and most electronics retailers stock RG-6 coaxial cables in various lengths. Online retailers like Amazon also carry them. Look for cables labeled "RG-6" with "F-type connectors" already attached. Prices typically range from $10 to $25 depending on length and shielding quality.
