Omnidirectional ISM antenna
An omnidirectional antenna is designed for receiving signals in ISM (Industrial, Scientific, and Medical) technology. It operates in the 433 MHz and 868 MHz frequency bands. With a high IP67 protection rating, it is suitable for both outdoor and indoor installations where resistance to dust and water is required.
From the antenna, a 3-meter-long RG174/U cable is led out, providing a flexible and easy connection to various devices. The cable is terminated with an SMA (male) connector. This connector is a common standard for connecting to most wireless modules and devices.
The antenna is ideal for applications in IoT (Internet of Things), industrial automation, security systems, remote monitoring, remote control, wireless sensors, and other devices utilising the 433 MHz and 868 MHz bands.
Connector specifications SMA:
These are high-frequency connectors with screw connection mechanisms. The characteristic impedance of the connector is 50 Ohm and the operating frequency range up to 18 GHz. There are two types of SMA connectors, namely SMA and RP-SMA. Most of the current cellular routers are equipped with SMA connectors for connecting Wi-Fi/2G/3G/LTE/GPS antennas terminated by proticates. It is also used as a standard connector in RF measuring technology. They are characterized by high reliability, durability, high mechanical stability and optimal electrical properties.
Cable specifications RG174/U:
The cable labeled RG174/U is a basic variant of a coaxial cable that is compatible with connectors applicable to a cable diameter of 2.8 mm. The characteristic impedance of the cable is 50 Ω. The reduction factor is fixed at 0.66. The operating temperature range is -20 to 80 °C.
It is most often used for creating cable adaptors with connectors such as BNC/FAKRA/FME/MCX/MMCX/N/SMA/SMB/SMP/TNC and others. It is ideal for short and bending stressed connections in measuring and telecommunications technology, for GPS/GSM/WLAN antennas, antenna leads etc.
