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. I hope that it will help readers decide which is the best choice for them.

Please watch the below video to see how BNC crimp-on connectors are attached to RG59 cable.


What Does IEC Connector Mean?


An IEC connector refers to a type of electronic cable that meet the International Electrotechnical Commission (IEC) standards. The specification for IEC connectors is IEC-60320. The connectors mount with cables are commonly referred to as female connectors or sockets, whereas the connectors mount with panels are known as male connectors or plugs.

IEC-60320 is a standard for male and female connectors used in cables and electric devices such as computers, workstations, laptops, printers and so on. Note that the IEC-60320 standard applies to different range and types of electrical devices. There is a range of standardized connectors that differ in regards to current capacities, temperature ratings and number of conductors. The main purpose of these cables is to attach an electronic appliance to its power source.

What Is an RCA Connector?


Radio Corporation of America (RCA) jacks and plugs are found on some of the most commonly used varieties of radio frequency (RF) coaxial cables. A male RCA connector consists of a central contact pin and an outer sleeve, each of which can be crimped or soldered to a shielded wire within a cable. Multiple RCA cables are typically required for any given application, since each one can only carry a single audio or video signal. Three RCA cables are required for a system that has stereo audio and composite video, while five are needed for stereo audio with component video. Modern high definition video signals can be transmitted through analog RCA connectors, though digital signals require different solutions.


The RCA connector was invented in the 1940s and was first used to connect an amplifier to a phonograph. They are sometimes referred to as phono connectors due to this original purpose, even though they can be used to carry both audio and video from many different devices. By the 1950s, the RCA connector had largely replaced the tip ring sleeve (TRS) connector in most high fidelity audio systems, and they remained popular even after the introduction of digital audio and video. Most audio-visual equipment comes equipped with RCA connectors, and some speakers do as well.


5 Common Types of RF Connectors


Do you find it difficult to identify what RF connector type you're going to use in an application? If so, don’t worry. In this article, you will learn about the different types of RF connectors and what applications they are commonly used for.


RF (radio frequency) connectors are connectors that are designed to work at radio frequencies for signal transmission of products like radios, antennas, coaxial cables, etc. However, these connectors have a variety of types.


Here are 5 of the most commonly used types of RF connectors.




2. UHF Connector


The Ultra High Frequency (UHF) connector is also a threaded RF connector that carries signals at frequencies up to 100 MHz. It’s not waterproof and non-constant surge impedance. It can be used in amateur radio, Citizens band radio, and marine VHF radio applications.


3. TNC Connector


TNC is a threaded version of BNC connector and has better performance compared to BNC connector at microwave frequencies. It is used in radio and wired applications.


4. BNC Connector


BNC is a miniature quick connect/disconnect RF connector commonly used at low frequency applications. It is originally used for the military sector and has gained wide acceptance in composite video on commercially used video devices and RF applications up to 2 GHz.


5. SMA Connector


SMA or SubMiniature version A connectors are semi-precision coaxial RF connectors operating up to 18 GHz, though some proprietary versions are rated to 26.5 GHz. It is commonly used in RF power amplifiers, RF isolator, microwave systems, mobile telephone antennas, WiFi antenna systems and radio astronomy at 5 GHz+.
