After you’ve sorted out the best antenna placement, you’ll need to connect your antenna to your TV. All over-the-air HD antennas connect to a TV using a coaxial cable. The coaxial (or coax) cable has long been used to deliver video and audio signals to TVs. But are they all created equal? Short answer, no. So if you want to ensure that you get crystal clear video, high quality sound you’re going to want to get the best coaxial cable available.

What Are Coaxial Cables?

The coaxial cable (also known as “coax”) is the most common cable used to transmit video signals. Coaxial cables have a copper conductor surrounded by non-conductive insulation enclosed by shielding that protects against electromagnetic interference. Finally, the cable is wrapped in a strong, lightweight plastic jacket.

There are three different types of coaxial cables available: RG59, RG6 and RG11. The difference between these cables is the width of the copper conductor. The larger the conductor, the less degradation there is in signal quality over long distances. The most common coaxial cable used for home television setups is RG6. All of our picks for the best coaxial cables are RG6. You won’t find any RG11 cables on this list simply because they’re only necessary if you want to transmit signals over 500 meters, which doesn’t affect the average homeowner.
