GPS Antenna Setup Make sure the connection is hand-tight with the SMA connector at the end connecting to the unit before giving it a quarter turn with a hall wrench to make sure it is properly secured. It is very important that you DO NOT kink the RF cable going to the GPS antenna. If it gets bent hard or is dented from being caught in the window or door frame too firmly, cable shielding performance will quickly degrade.

Magnetic Mount Antenna wear factors to consider: Replacing drive-study mag mount antennas annually, especially in high-usage scenarios or extreme climates, helps maintain performance and signal quality by minimizing connector wear, RF losses, and weathering effects. Hereʼs a breakdown of why this is important: Connector Wear and Tear: Frequent attachment and detachment wear down connectors over time, leading to poor connection stability.

VSWR Graph VSWR 1.277 Reflected Power 1475.00MHz 1575.00MHz 1675.00MHz What is VSWR? The Voltage Standing Wave Ratio (VSWR) is a measurement of how well an antenna is matched to a source impedance, typically 50-ohms. It is calculated by measuring the voltage wave that is headed toward the load versus the voltage wave that is reflected back from the load.
