When experimenting with GPS or RF it can be very handy to have the antenna on the top of your house or car with a clear view of the sky while you stay in doors and warm at your keyboard. This 2m (6.5ft) magnetic mount SMA extension does a great job of connecting your receiver or radio to a distant antenna with as little RF loss as possible.
The cable is the thicker, lower loss, RG58 which is ideal for high power (≥100mW) transmissions.
While the magnetic strength is high, it is not intended for automotive applications as we don't know what size antenna you're mounting. While you're stationary, this mount should be perfect for a Swarm Satellite antenna, allowing you to use the roof of your car as the ground plane.
Note: This product uses SMA connectors. Please see the product photos to make sure your antenna and equipment will be compatible.
Jargon buster
Plain-language definitions for the technical terms used above.
- GPS
- The US satellite navigation system used by GNSS receivers to calculate position and time. Support for GPS is important because it is widely available and often used together with other constellations for more reliable positioning.
- ground plane
- A ground plane is a large area of copper on a circuit board connected to ground. It helps provide a stable return path for signals and is especially important for reducing noise in high-speed connections.
- RF
- RF means radio frequency, referring to signals used for wireless communication and other high-frequency electronics. A low-noise, stable power supply is important for RF circuits because power noise can affect signal quality and measurements.
- SMA
- A threaded coaxial connector commonly used for antennas. It matters because you need antennas with matching SMA connectors, or suitable adapters, for the LTE and GNSS antenna ports.
