A coaxial cable is the least glamorous part of a TV or internet setup and the one most often blamed, correctly, when channels pixelate or a cable modem keeps dropping. The job is simple: carry a radio-frequency signal from the wall plate, antenna or dish to the box with as little loss and as little outside interference as possible. That comes down to four things: the cable type (RG6 for almost every home run today), the shielding, the connectors, and buying the right length rather than coiling twenty spare feet behind the TV. We ranked the coaxial cables in our accessories catalog by those points and by what hundreds to tens of thousands of owners report after installing them.
We have not swept every one of these on a signal meter ourselves; the verdicts rest on the spec sheets and the owner review history. Prices are not printed because they change daily; every button opens the live Amazon page. Camera cables with BNC ends are a different job and have their own guide, BNC security camera cables. If the coax feeds an internet connection, our modem router combos guide covers the box at the other end, and HDMI cables covers the last hop to the screen.
How we picked
- RG6 at 75 ohm for every TV, satellite and cable internet pick, since that is what modern providers and tuners expect.
- Shielding stated by the maker. Triple or foil-plus-braid shielding earns a place; unshielded bargain cable does not.
- Factory-fitted connectors, ideally compression F-type, because a badly crimped end causes more trouble than the cable itself.
- Useful extras such as a female-to-female coupler or TV adapters counted only when listed in the box.
- Owner feedback from a hundred to tens of thousands of reviews, with connector fit and stiffness complaints noted.
The picks
G-PLUG 10FT RG6 Coaxial Cable Extender - Coax Cable Cord, Triple Shielded

G-PLUG’s 10-foot RG6 is the cable most people actually need: long enough to get from a wall plate to a modem, cable box or TV with a little slack, and short enough that there is no coil of spare cable acting as an aerial behind the furniture. It is 75 ohm RG6 with triple shielding and compression F-type connectors on both ends, which grip the cable jacket all the way round instead of relying on a crimp ring. The maker lists it for cable modems, routers, DVRs, antennas and satellite receivers and names the big US providers, and a female-to-female F81 coupler is in the bag so it can extend a cable you already have. Tens of thousands of owners give it an excellent owner rating, by far the deepest record on this page. The jacket is flexible PVC for indoor and sheltered outdoor use, not burial. For a standard hop, it is the easy choice.
- Tens of thousands of owner reviews with an excellent owner rating
- Compression connectors rather than cheap crimped ends
- Coupler included for extending an existing cable
- Flexible PVC jacket rated for indoor and protected outdoor runs
- 10 feet is too short for room-to-room runs
- No right-angle adapter for tight wall plates
- Jacket is not rated for burial or in-wall use

When the antenna is on the roof or the modem lives two rooms from the wall plate, this 50-foot RG6 is the pick. It is an 18 AWG, 75 ohm cable with foil and braid shielding, rated by the maker to 3 GHz so it suits satellite receivers as well as cable TV and broadband, and the PVC jacket is UV-resistant with moisture-resistant, corrosion-resistant threaded connectors for outdoor runs. The pack is generous: one F81 female-to-female coupler and two F female to TV male adapters, which covers older sets and antenna leads with push-on sockets. Thousands of owners give it an excellent owner rating, and the listing also comes in other lengths and in white. Every extra foot of coax costs a little signal, so do not buy 50 feet for a 6-foot gap, and the cable is naturally stiffer than a patch lead. For a long, exposed run, it is the best value here.
- Thousands of owner reviews with an excellent owner rating
- UV-resistant jacket for outdoor antenna runs
- Coupler and two TV adapters in the pack
- Rated to 3 GHz for satellite as well as cable
- Fifty feet is more loss than you want for a short hop
- Foil and braid shielding rather than quad shield
- Stiffer to route than a short patch cable
BlueRigger RG6 Digital Coaxial Audio Video Cable (10FT, Male F Type Connector, Triple Shielded) - Coax Cable for HDTV, CATV, DVB-T2/C/S, Modem, Radio, Satellite Receivers

BlueRigger’s 10-foot RG6 is the cable to buy when you want the purchase backed for as long as you own it: the maker offers a lifetime warranty with US-based support. On paper it is also the best-built short cable here, with a pure copper center conductor rather than copper-clad steel, triple shielding, a durable PVC jacket and 24K gold-plated F-type connectors that resist corrosion. The maker lists it for HDTV, cable TV, satellite receivers, cable modems and radio, and notes a consistent 75 ohm impedance along the whole length. Over a thousand owners give it an excellent owner rating. It is described as an indoor cable, so it is not the one to leave on a sunny wall, and there is no coupler or adapter in the pack. For a modem or TV hop where you would rather pay once, it is the dependable option.
- Lifetime warranty with US-based support
- Pure copper center conductor
- Gold-plated, corrosion-resistant connectors
- Over a thousand owner reviews with an excellent owner rating
- Maker describes it as an indoor cable
- No coupler or adapters in the pack
- Fewer owner reviews than the G-PLUG
energeaster 6FT RG6 Coaxial Cable with F-Type Connector, White Coax Cable

Most coax is black, which is fine behind a TV stand and ugly along a white skirting board. The energeaster is a 6-foot RG6 patch cable in pure white, built with triple-layer shielding of foil, braid and foil to keep out RF and mobile-signal interference, and solid compression F-type connectors with rubber O-rings at the joints to block moisture and dust. It is 75 ohm, as cable TV, satellite and internet gear expect, and a female-to-female coupler ships already attached so it can extend an existing lead. Hundreds of owners give it an excellent owner rating. Six feet is a patch length: enough from a wall plate to a modem on the same shelf, not enough to cross a room. The brand is newer than BlueRigger and the record is shorter. For a visible run in a light-colored room, it is the neat choice.
- White jacket blends in on light walls and trim
- O-ring sealed compression connectors
- Coupler ships attached to the cable
- Hundreds of owner reviews with an excellent owner rating
- 6 feet only reaches gear close to the wall plate
- Smaller review base than the top three
- Newer brand
Coaxial Cable 3ft/6ft/10ft/15ft/25ft/50ft/60ft/75ft/100ft, RG6 Coax Cable

The right coax length is the shortest one that reaches, and this listing is the easiest way to buy exactly that: nine lengths from a 3-foot jumper to a 100-foot run on a single page. It is 75 ohm RG6 with compression F-type connectors and a sturdy waterproof outer sheath that the maker rates for indoor and outdoor use, and it is listed for cable TV and satellite receivers, modems and DVRs. Hundreds of owners give it an excellent owner rating. The trade-off is information. It is an unbranded cable, the listing talks about superior shielding without saying how many layers, and no coupler or adapters are mentioned, so treat it as a plain, well-reviewed RG6 and nothing more. For a 3-foot jumper between a splitter and a box, or a 75-foot run where the branded options stop at 50, it fills the gaps.
- Nine lengths from 3 ft to 100 ft
- Compression connectors
- Waterproof sheath for outdoor runs
- Hundreds of owner reviews with an excellent owner rating
- Unbranded, with a thin spec sheet
- Shield layer count is not stated
- No coupler or adapters listed
Goobay 50910 Antenna Cable 0.5 m / Coaxial Male to Coaxial Female / SAT Cable Coaxial Cable Satellite Cable 70 dB / Double Shielded / TV Cable HDTV / White / TV Cable 0.5 m

Not every TV and radio port is a threaded F connector. Many sets, FM and DAB tuners and imported receivers use the push-on coaxial antenna plug, and Goobay’s 50910 is a half-meter lead with a coaxial plug on one end and a coaxial socket on the other for exactly those ports. It is a 75 ohm cable with foil and 32-strand braid shielding rated at 70 dB, nickel-plated contacts and plugs molded on both ends to keep out dust and take strain. Over a thousand owners give it a strong owner rating. Be clear about what it is not: it will not screw onto a US cable box or modem, the conductor is copper-clad steel, and the shielding is double rather than triple. As a short extension or wall-socket lead for a set with antenna-style ports, it is tidy and well proven.
- Molded plugs protect against dust and strain
- Push-on coaxial plug and socket for antenna-style ports
- Over a thousand owner reviews with a strong owner rating
- Very short, so almost no signal loss
- Not a threaded F-type cable, so it will not screw onto a US cable box
- Double shielding, not triple
- Copper-clad steel conductor
Bolton400 Coaxial Cable 50ft Black, N Male to N Male - LMR400 Equivalent

The Bolton400 is here for one job: connecting an outdoor antenna to a cell signal booster, LTE router, ham radio or other 50 ohm equipment over a long run. It is built to LMR400-equivalent specifications, with a maker-stated loss of about 6 dB per 100 feet, triple shielding, a CL3-rated black jacket and factory-fitted N male connectors on both ends, which is what most booster kits and outdoor antennas use. The small group of owners who have reviewed it give it an excellent owner rating. It is not a TV cable. Televisions, satellite receivers and cable modems are 75 ohm devices with F connectors, and this 50 ohm, N-terminated cable will neither fit nor match them. It is also thick and stiff, so plan gentle bends. For anyone extending a booster or antenna feed, it is the right kind of coax.
- Very low loss for long antenna runs
- Factory-terminated N connectors
- CL3 rated jacket
- Excellent owner rating from a small base of reviews
- 50 ohm, so it is the wrong cable for TV, satellite or cable modems
- Thick and stiff to route
- Just over a hundred owner reviews

RG6, RG59 and 50 ohm cable
RG6 is the standard for home TV and internet today. It has a thicker center conductor and better shielding than the older RG59, so it loses less signal at the high frequencies that digital cable, satellite and broadband use. RG59 still turns up in old houses and on analog camera systems, and it is fine for short, low-frequency runs, but there is no reason to buy it new for a modem or a 4K cable box. Both are 75 ohm. Cable such as the Bolton400 is 50 ohm, a different family used for transmitters, cell boosters and wireless antennas. Mixing the two families causes reflections and loss, so match the cable to the equipment: F connectors and TV gear mean 75 ohm RG6.
How long should a coax cable be?
Buy the shortest length that reaches with a gentle curve at each end. Signal loss grows with every foot, and a tight coil of spare cable behind a TV can pick up interference. As a rough guide, 3 to 6 feet covers a box on the same shelf as the wall plate, 10 feet reaches most of the way across a media wall, and 25 to 50 feet is for another room or an attic antenna. If you need to join two cables, use a proper F81 coupler like the ones bundled with the G-PLUG, the 50-foot RG6 and the energeaster, and keep the number of joins to one. Never bend coax sharper than a soda can.
Shielding and connectors
Shielding keeps other signals out of your cable, which matters more now that phones and routers share nearby frequencies. Foil plus braid is the minimum worth buying; triple shielding adds a second foil layer and is the sensible default near a router or in an apartment block. Connectors matter just as much. Compression F-type ends, as on the G-PLUG and energeaster, clamp the whole circumference of the cable and rarely pull loose, while O-rings or molded boots keep damp out on outdoor runs. Tighten F connectors finger-tight plus a small nudge. A loose connector is the single most common cause of a flaky cable modem.
What coaxial cable do I need for a cable modem or TV?
A 75 ohm RG6 cable with F-type connectors. All of the RG6 picks here suit cable modems, cable boxes, TVs, antennas and satellite receivers. The Bolton400 is 50 ohm with N connectors and is for signal boosters and wireless antennas, not TV or cable internet.
Is RG6 better than RG59?
For modern TV and internet, yes. RG6 has a thicker conductor and heavier shielding, so it loses less signal at the high frequencies digital cable, satellite and broadband use. RG59 is acceptable for short analog runs but is not worth buying new for a modem.
Does a longer coax cable weaken the signal?
Yes, a little with every foot. Buy the shortest cable that reaches comfortably. A 50 ft cable is right for a run to another room or an antenna, but for a hop of a few feet a 6 or 10 ft cable will lose less and leave no coil of spare cable.
Can I join two coaxial cables together?
Yes, with a female-to-female F81 coupler. The G-PLUG, the 50 ft RG6 and the energeaster each include one. Every join adds a small loss and another place for a connector to work loose, so keep it to a single coupler where you can.
Can these cables be used outdoors?
The 50 ft RG6 has a UV-resistant jacket and moisture-resistant connectors, the energeaster has O-ring sealed connectors, and the multi-length RG6 lists a waterproof sheath. The BlueRigger is described as an indoor cable. None of them is rated for direct burial.
