Walkie talkies(two way radios) all need an antenna to transmit and receive signals. The communication coverage of radios depends on the signal, which is determined by the antenna. To some extents, the longer the antenna is, the longer you can reach.
But the radio connectors are varied in the market by different manufacturers. Each connector type has its unique uses and benefits. To connect an antenna to your device, you need the right connector for excellent performance. There are many antenna connectors and it can be confusing to know which one to choose. Let’s learn the different types of antenna connectors. It can help you a lot to find the right one.
What Are Antenna Connectors?
Antenna connectors allow radio frequency signal connection between an external antenna and radio equipment. They provide good electrical contact between the radio transmitter and the antenna. These connectors come in various shapes and sizes, suited for both active and passive antenna systems. You need to pay attention to the antenna frequency band.
F Connector and Adapters for other types of Connection
The F connectors are so easy and quick to install. These connectors are in the principal splitters, PAU, and another element of the installation, such as amplifiers, LNBs, and Satellite Receivers. This connector is normally found in a lot of devices. The F connector is also known as a Threaded Connector. There are two main types: 7 mm (6.8mm) is the most common and most used in coaxial cables, and the connector 5mm that is used in a thin coaxial cable, typically used in satellite systems. Although we can also find other F connectors.
Gender and Polarity
Are you trying to identify pin (male) and socket (female) connectors? You will find it easily by following these tips:
When mating two connectors, it is important to ensure that both connectors have the same polarity. For example, both should be RPSMA.
Typically, RF plugs are pin (male), and the threads are on the inside of the shell.
Typically, RF jacks are socket (female), and the threads are on the outside of the shell.
The shell of a plug (male) typically covers the shell of a jacket (female).
Let’s identify below connectors together.
A standard polarity plug (male) has a center pin that sticks out from the middle, and the plug’s shell has threads on the inside. Here we have shown an SMA plug, typically found on the end of a coaxial cable that connects to products such as cellular gateways or GPS receivers.
A standard polarity jack (female) has a socket in the middle designed to receive the pin from the plug (male), and the jack’s shell has threads on the outside. Here we have shown an SMA jack, typically found on a radio such as a cellular gateway or GPS receiver.
A reverse polarity plug (male) has a socket in the middle designed to receive the pin from the jack (female) connector, and the plug’s shell has threads on the inside. Here we have shown an RPSMA plug, typically found on the end of a coaxial cable that connects to products such as the RF451, RF407-series, and CR6-WIFI.
A reverse polarity jack (female) has a center pin that sticks out from the middle, and the jack’s shell has threads on the outside. Here we have shown an RPSMA jack, typically found on a radio such as our 900 MHz spread-spectrum and Wi-Fi devices.
