Usually, yes: an old satellite coax cable can often carry an over-the-air (OTA) TV antenna signal if the cable is intact and the rest of the signal path is compatible. You need a broadcast TV antenna; the cable only carries its signal. Existing satellite diplexers, switches, splitters, or power equipment may affect how it can be connected.
What you can reuse—and what you cannot
Think of the antenna and cable as separate parts. A purpose-built OTA antenna receives broadcast signals; coax carries those signals from the antenna to a TV or tuner. A satellite dish reflector and its low-noise block (LNB) are not thereby converted into a broadcast TV antenna.

Terk says its TV antenna can use the same wiring as a satellite dish in a particular setup that uses diplexers. That supports the possibility of reusing a cable run, not a guarantee that every satellite installation will work unchanged. Terk TV55 support

Inspect the cable
Check accessible sections of the jacket and connectors, especially any outdoor portion. Look for damage, corrosion, or weathering, and read the markings printed on the cable. Viasat’s satellite cabling job aid identifies cable marking details such as frequency, RG type, conductor material, and impedance, and specifies RG-6 connectors for its system. These are useful things to identify, not universal pass-or-fail rules for an OTA installation. Follow the antenna maker’s cable and connector requirements. Viasat cabling job aid

An RG-6 label alone does not guarantee reception: condition, connectors, the rest of the signal path, and the antenna’s requirements matter too. The available guidance does not establish a universal maximum cable length or a reception guarantee. If the cable is damaged, corroded, or cannot be identified well enough to compare with the antenna instructions, replacing it with a suitable cable may be the safer choice.
Trace what remains connected
Identify any diplexers, multiswitches, splitters, wall plates, or power injectors between the outdoor cable and the TV. Their role and compatibility depend on the existing layout and the antenna model. Terk documents one shared satellite-and-antenna arrangement using diplexers; do not treat it as a universal wiring diagram. Terk also warns not to install its power injector in the described satellite-system arrangement. For a different antenna, use that model’s instructions rather than applying Terk’s directions.

Connect the antenna and scan for channels
- Choose an OTA antenna. Select a model designed for broadcast TV reception and follow its instructions for cable, connectors, mounting, and any power requirements.
- Determine the cable route. Trace the existing run and identify satellite equipment still in line. Use the antenna maker’s instructions and equipment labels to determine what must be disconnected, bypassed, or configured.
- Connect the feed line. Attach the antenna to the existing coax route using the prescribed method. Connect the indoor end to the TV’s antenna input or the tuner input specified by its manufacturer.
- Scan for channels. On the TV or tuner, select its antenna or over-the-air mode and run a channel scan. Menu labels and steps vary by device; there is no single scan path that applies to every TV.
If reception is poor, check the connectors and signal path first, then consult the antenna instructions and local reception guidance. A cable’s satellite history or RG-6 marking by itself cannot establish reception at your location.
Install outdoor equipment safely
Use the antenna maker’s mounting and grounding instructions and follow applicable local electrical rules. Viasat’s grounding guide says, in the context of its satellite installation, “Both the antenna and the COAX cables require a ground.” That is installation guidance for its described context, not a complete grounding code for every OTA setup.

Keep antennas and supporting structures away from power lines during installation and removal. US regulation, 16 CFR § 1402.1, addresses warnings about electrocution hazards from outdoor TV antennas and their supporting structures near power lines. If the installation or local requirements are unclear, seek qualified help.
