Directional antenna WiFi

Directional interior antenna with a gain of 4 dBi, working in 2400/5800 MHz band and is suited for receiving/transmitting Wi-Fi signal. The antenna is primarily suited for households. It operates well with WiFi routers and modems. It comes with 3M sticker for easy assembly. The antenna is supplied with 200 mm cable RG174/U with SMA-RP(pin f) connector.

It is not advisable to place the antenna on a metallic substrate. Location on the metal cause change of radiation pattern and also basic parameters of the antenna.

Connector specifications SMA: 

These are high-frequency connectors with screw connection mechanism. 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 much cheaper variant of a coaxial cable that is compatible with connectors applicable to a cable diameter of 2.8 mm. It is mainly used for the frequency range 0 - 1 GHz, it can also be used for higher frequencies, but at the cost of higher attenuation – see the attached attenuation table below. 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.
