GPS GLONASS antenna QOLTEC 57054 with magnetic base, 28 dB gain

Description: Enhanced satellite signal for your navigation systemNavigation devices, like other devices requiring constant access to GPS signals, can lose accuracy in difficult conditions in dense urban areas, between tall buildings, in forests or in places with limited visibility. The Qoltec GPS antenna was designed to eliminate these problems. With a narrow bandwidth of 4 MHz, the antenna precisely filters the signal in the GPS L1 band (1575.42 MHz), which effectively reduces interference from adjacent frequencies and improves positioning stability. The low VSWR 1.5 ensures a perfect match between the antenna and the receiver, minimising reflected signal loss and guaranteeing maximum RF path efficiency.Designed for stable navigation reliable in all conditionsThe omnidirectional design ensures uniform signal reception from multiple directions, which is particularly important in mobile applications and in places where the position of the device may change. This allows the antenna to maintain stable contact with more satellites simultaneously, regardless of the orientation of the device. RHCP (Right-Hand Circular Polarisation) ensures proper cooperation with GPS satellites that transmit signals in the same polarisation. FAKRA connector minimal signal lossThe presented model is made with attention to the smallest details. The high tightness class is characterised by weather resistance, and the copper material conducts electricity perfectly and is resistant to corrosion.High gain of 28 +/- 3 dBi, achieved thanks to the integrated LNA amplifier, significantly increases the sensitivity of the receiver, enabling operation even with a weak or partially obstructed signal. The antenna is equipped with a specialised FAKRA connector, which ensures the highest connection reliability in demanding environments such as cars, industrial vehicles and public transport systems. The FAKRA connector is characterised by high mechanical resistance, minimal signal loss, stable operation and key and colour coding to prevent incorrect connection.Stable mounting while drivingThe antenna is equipped with a magnetic base that allows for quick and stable mounting on metal surfaces, such as the roof of a vehicle or bodywork components. A strong magnet ensures a secure hold even while driving, minimising the risk of the antenna shifting or falling off. Thanks to this solution, installation does not require drilling or the use of additional tools, and the antenna can be easily removed and moved to another location at any time. | Type: Omnidirectional | Usage: Outside | Antenna gain: 28 | Impedance: 50 | Color: Black | Dimensions: (D/L x W x H): 48 x 36 x 15 mm | Weight: 630 | Other features: Wireless standard: 1575.42 MHz (GPS L1) + 1602MHz (GLONASS)

How to use

Position the antenna on a clean, flat metal surface with a clear view of the sky for best satellite reception, such as a vehicle roof. Route the cable to the GNSS receiver or tracker and connect the antenna to the receiver’s external antenna input. If the receiver requires power for the active antenna, ensure the receiver supplies the correct voltage according to its specifications. Avoid placing the antenna under thick coverings or inside enclosed compartments that block signals. After installation, verify signal reception and position fix using the receiver’s diagnostics.

Recommendations

For optimal performance, place the antenna where it has an unobstructed view of the sky and secure it on a ferrous surface. Regularly inspect the cable and connector for wear or damage, and clean mounting surfaces to maintain good magnetic contact. If installation is permanent, use strain relief on the cable and protect connectors from moisture.
