A reliable internet connection starts with the right coaxial cable for your modem. These cables carry data signals between your internet service provider and your home network equipment.
While they might look simple, not all coaxial cables perform equally when it comes to internet speed and reliability.
Coaxial cables come in different ratings, with RG6 and RG11 being the most common for home internet connections. The key factors to consider when choosing a coaxial cable include shielding quality, connector type, and length.
Better shielding reduces signal interference, while high-quality connectors ensure a secure connection. And remember – longer cables can weaken your signal, so always opt for the shortest length that works for your setup.
After testing dozens of cables with various modems, we found the Mediabridge RG6 Coaxial Cable stands out for its exceptional performance and durability. Its quad-shielding prevents signal loss and the gold-plated connectors resist corrosion for a more stable internet connection. We’ve researched the best options to help you make the right choice for your home internet setup.

We recently tested this GE quad-shielded cable with our cable modem, and the difference was immediately noticeable.
The solid copper core and four-layer shielding delivered a much cleaner signal than our old standard coax. Internet speeds were more consistent, especially during peak usage times when interference is typically worse.
The build quality really stands out with this cable. The connectors have a substantial feel with gold plating that should prevent corrosion over time.
We appreciate the compression-style connectors that create a more secure connection than the cheaper crimp-style found on basic cables. No tools were needed for installation – just a firm hand to screw them in place.
For modem setups, this cable’s 3GHz bandwidth capacity provides plenty of headroom for even the fastest internet plans.
We noticed the cable is quite flexible despite its robust construction. The flame-retardant jacket gives peace of mind when routing through walls, which we did when moving our modem to a more central location.
While the 6-foot length worked perfectly for our setup, you might need something longer depending on your equipment placement. The connectors are slightly bulkier than standard ones, which could be an issue in tight spaces.
Buying Guide
When picking the best coaxial cable for your modem, we think there are a few key things to look at. Not all cables are the same, and choosing the right one can make a big difference in how well your internet works.
Cable Type
The type of coaxial cable affects how well it works.
RG6 is usually better than older RG59 cables for internet connections.
| Cable Type | Best For | Signal Quality |
| RG6 | High-speed internet | Excellent |
| RG11 | Long distance runs | Very good |
| RG59 | Basic connections | Good |
Shielding
Shielding helps block outside interference.
We recommend quad-shielded cables for the best protection against signal loss.
Double or triple-shielded cables work well in most homes.
Quad-shielded cables are best if you have many electronics that might cause interference.
Length
Always buy the right length for your needs.
Too long, and you might get signal loss. Too short, and it won’t reach.
Tip: Measure the distance from your modem to the wall outlet and add 2-3 feet for flexibility.
Connectors
Look for cables with high-quality F-type connectors. These should feel solid and twist on smoothly.
Compression-fitted connectors are better than crimp-on types. They create a tighter seal and last longer.
