GPS/GLONASS antenna QOLTEC 28 dBi 50 W with SMA right-angle connector

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. SMA Right Angle Connector ideal for compact devicesThe presented model is manufactured with attention to the smallest details. The high ingress protection rating is characterised by weather resistance, and the copper material conducts electricity perfectly and is corrosion resistant.High gain of 28 3 dB, 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 right-angle SMA connector, which facilitates installation in confined spaces an ideal solution for GPS trackers, IoT modules, telemetry systems and compact electronic devices.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 37 x 15 mm | Weight: 600 | Other features: Wireless standard: 1575.42 MHz (GPS L1) + 1602MHz (GLONASS)

How to use

Mount the antenna in a location with a clear view of the sky to maximize satellite visibility, avoiding obstructions such as metal structures or dense foliage. Connect the right-angle SMA connector to the compatible receiver input, ensuring proper thread engagement without excessive force. Route the coaxial cable to prevent sharp bends near the connector and secure the antenna using appropriate clamps or brackets for the installation environment. After connection, verify the receiver's signal strength and adjust antenna position if necessary for optimal reception.

Recommendations

For best performance, install the antenna on a non-metallic or isolated mounting surface when possible and maintain a clear hemisphere toward the sky. Regularly inspect the connector and cable for corrosion or damage in outdoor installations, and use weatherproofing measures at the connector interface if exposed to the elements.
