That also makes it a good choice for a closed circuit television CCTV video surveillance system. By using this type of cable, you can run the power and video for your security cameras simultaneously, effectively cutting your install time in half. Satellite and internet signals run at higher frequencies than traditional analog video, and when TV broadcasts changed from analog to digital, and cable companies started switching to digital, the higher freuqencies made it necessary to find a more effective coaxial cable.
RG6 cable was designed to fulfill these requirements. It has a larger conductor, which gives you much better signal quality. The dielectric insulation was made thicker as well. RG 6 is also made with a different kind of shielding, which allows it to more effectively handle Ghz level signals. While many RG 59 cables uses a foil shield in addition to the braid, RG 6 made it mandatory. The braid was originally in a looser weave e. Deciding between RG 59 and RG 6 is only part of the process.
Each class of cable can have different types of shielding or jacket and may or may not be rated for your chosen installation. Some say that it means "universal" or "for general utility use. If you need a certain type of jacket, make sure and check the specs. But we'll get into different jacket types later on. Shielding prevents 'noise' from interfering with your signal, and therefore preserves your signal quality.
Coaxial cables usually come with two types of shielding: braid and foil. Most coaxial cables include both although some RG 59 cables still use single shielding. In general, the more shielding you have, the better your cable will perform, especially in longer runs, but there are differences in what the shields protect.

This is a question that is underresearched: For example, wikipedia does have an article on Coax Cable and comparison of different types, and you'll notice that these things differ in more than loss.
What's a bit problematic here is that "ham radio" is not a single use case, and especially not a single frequency. In engineering, there's no global "it's better", it's always relative to some aspect for some specific use case! You can easily fix the question by telling us what you want to do specifically, what you researched and what you've got that you want to connect.

A 75 Ohm BNC doesn't mate reliably with a 50, and a 50 damages a But "everyone on the internet is wrong, I'm right" is not a constructive way to engage. If you want to show that everyone is wrong, then you are the one that must be prepared to offer references. Skip to content What is rg58 cable? The RG58 is a 4.
Are all RG6 cables the same? Which is better RG8 vs RG58? Is RG58 a 75 ohm? How long can you run coax cable without loss? Can I use 75 ohm cable instead 50? How far can you run RG-6 cable for Internet?
Can you splice RG58 cable? Are all TV cables the same? What type of cable is 10Base T? Does length of coaxial cable affect signal? How many watts can RG8X handle? The maximum power handling is watts. Is video 50 Ohm or 75 Ohm?
