There are 2 types of BNC connectors : 50 Ohm and 75 Ohm. The value of ohms indicated basically measures electrical impedance along the coaxial cable. BNC type connector is easy to install with a simple “snap and lock” mechanism, which ensures a high-quality connection.
The BNC type come in handy when you need to combine them with, fox example an 1.0/2.3 connector , on the end of the coaxial cable.
Most projects require the 50 Ohm cable assemblies which provides much better results than a 75 Ohm cable. The coax cable is measured by impedance that is the resistance to the flow of electrical energy. The smaller the ohm, the better the performance. If it looks like this ,what application require the 75 ohm BNC RF cable?
Both 50ohm and 75 ohm connectors can mate without damage, but you can’t expect to get the same video quality if you really mix and match them. For example, if you install a traditional 50 Ohm BNC connector on a 75 Ohm coaxial video cable, the digital signal would be significantly distorted.
50-ohm BNC connectors are basically used for older analog video applications. But in the higher performance A/V applications like HDTVs, 75-ohm BNC devices are necessary. 75 Ohm BNC connector and Cable assemblies can also be used for analog purposes. The 75-Ohm coaxial cable delivers the best results if power storage is not the issue, but rather the desire for the most efficient way to move a signal through a cable without losing any energy. Fox example , the 75-Ohm cable is good choice if you'd like to adopt when powering up devices like home theater gear, BluRay devices, HD televisions, and the like.
We have kinds of 75ohm BNC connectors and Pre-made 75 Ohm BNC cable assemblies. RF cable assembly P/N AC-B04SP-M08SP-1855A-30d5 and AC-B04SP-B04SP-1855A-457d2 and other 75 ohm rf cable assemblies from Superbat are a good selection of coaxial cables for radio, antenna ,interconnect and Video Camera & Moniter with RF components.
