This shielded design enables signal carrying voltage to flow through the central conductor with minimal interference from outside electrical and/or magnetic fields. They generally consist of four layers-the inner conductor layer, the inner conductor insulating layer, the conductive shield layer, and the insulating outer jacket layer. We have RG59 kits that include your choice of all three connector types reviewed in this article as well as the tools that you need.Coaxial cables are a type of transmission cable used to transmit radio frequency (RF) signals. If you are looking for a supplier for connectors, cables, and tools, please take a look at the CCTV cable installation kits that my company offers. After all, the last thing you want to spend a lot of time on is attaching BNC connectors to cable. If you are really comfortable with a certain type and you are efficient at attaching that type, go with it. One factor in making a decision in which BNC connector is best for you is the time it takes to attach. I should mention that I do not have anything really bad to say about using BNC crimp-on connectors, but I prefer the other two methods after testing all three. If you have the room for the extra length of these two connectors combined, this is probably my favorite. Compression tools are not cheap, but they are worth it. There is very little guessing when you use this method. Nothing really beats how secure a compression connector is when attached to coax, and I really like the way that the core of the coax is exposed on the f connector. When cut correctly, I found them to be very secure. However, after taking the time to understand how important getting the length of the cuts just right is and also realizing that the TL-22 coax stripper tool makes the cuts exactly where you need, I really like BNC twist-ons. My opinion is this: before creating the three videos that appear in this article and spending sufficient time practicing with each type of connector, I was convinced that BNC twist-on connectors were not a good choice. There is a reason that different types of choices to exist and there is no one size fits all answer here. The below video demonstrates this method of attaching a compression F-connector to RG59 cable, then screwing on a BNC male. This longer connector method, can make working in tight spaces a challenge. In some cases, installers have a limited amount of space and need the coax to bend away from the camera shortly after the connection is made. when you combine the length of the F and BNC connector, it is longer than a twist-on connector. It is simple for them to attach a BNC screw on connector to an F-connector. These installers have been attaching F-connectors using a compression tool for years – they are very good at it. Cable TV uses the same RG59 and RG6 coax cable that CCTV cameras use. The other reason that this is a favorite method among professional installers is because many CCTV installers also perform cable TV installations. With BNC compression connectors, the core of the coax is hidden when you compress the fitting onto the cable. The reason that many installers prefer this method is because there is no guessing the correct length of the coax core when you attach F connectors (because the coax core is visible and can be trimmed after). One piece BNC compression connectors exist (which is one method), however, many installers prefer to attach a compression F connector to coax cable first, then screw on a BNC connector to the F-connector. There are two popular methods for attaching compression BNC connectors. Please watch the below video to see how BNC crimp-on connectors are attached to RG59 cable. The attachment process takes a little longer than the other methods, but this is still a favorite among professional installers because the connector stays very secure when done. Installation using two piece BNC crimp-on connectors requires two tools: a coax cable stripper and a coax crimping tool. The two piece style is much more popular, so that is the type that we will discuss here. So, the coaxial cable that connects these types of devices needs to have BNC male connectors on both ends of the cable run.Ĭrimp-on BNC connectors are available in two styles: 2 piece and 3 piece. Almost always, devices such as CCTV cameras, surveillance DVRs, and security monitors have a BNC female video input or output on them. They are the industry standard connector for CCTV video surveillance systems. I hope that it will help readers decide which is the best choice for them.īNC connectors are used in video applications with RG59 and RG6 coaxial cable. What is the best BNC connector? This article will discuss some of the most popular options that are available and present videos on how to connect these types of BNC connectors to coax cable.
