Product information

Description

The Qoltec 57018 directional antenna is designed to improve mobile broadband reception at home, in the office or in a vehicle. It supports 4G LTE speeds up to 300 Mb/s and is built with precision using high-quality components. The antenna has a compact form factor (height 195 mm), lightweight construction (31 g) and a durable design suitable for indoor and mobile use.

Advantages

The antenna provides improved signal reception and data transmission thanks to its directional pattern and 7 dBi gain. It uses a male N-type connector with 50 Ω impedance for reliable coaxial connection and supports up to 50 W of power. A magnetic base and robust construction enable mounting on vehicle roofs or other metallic surfaces for stable reception while traveling.

Suitable for

  • Enhancing 4G LTE reception for home routers and indoor modems
  • Improving mobile internet signal in cars and RVs
  • Temporary or portable deployments requiring a compact directional antenna

Key specifications

  • Frequency band: 0.6 - 27 GHz
  • Antenna gain (max): 7 dBi
  • Connector type: male N-type
  • Impedance: 50 Ω
  • Maximum power: 50 W
  • Weight: 0.031 kg
  • Height: 195 mm

How to use

Connect the antenna to your modem or router using a suitable coaxial cable and the male N-type connector. Position the antenna towards the source of the mobile network signal to maximize reception; when used on a vehicle, attach the magnetic base to a clean metallic surface such as the roof. Ensure connections are secure and avoid sharp bends in the cable to maintain signal quality.

Usage recommendations

For best results, place the antenna at a higher position and orient it toward the nearest cell tower. Verify compatibility with your device’s connector and frequency bands before installation. Regularly check the mounting and cable connections, especially after travel, to maintain optimal performance.

Features

International Protection (IP) code: The IP code classifies and rates the degree of protection provided against the intrusion (including body parts such as hands and fingers), dust, accidental contact, and water by mechanical casings and electrical enclosures. It is published by the International Electrotechnical Commission (IEC). The digits (characteristic numerals) indicate conformity with the conditions summarized in the tables below. Where there is no protection rating with regard to one of the criteria, the digit is replaced with the letter X. an electrical socket rated IP22 is protected against insertion of fingers and will not be damaged or become unsafe during a specified test in which it is exposed to vertically or nearly vertically dripping water. Another example is the Sony Xperia Z Ultra, one of the first cellular phones to be IP-rated; it is rated at IP58 and marketed as "dust resistant" and can be "immersed in 1.5 meter of freshwater for up to 30 minutes".
