The WB-512M antenna is a magnetic mount antenna with an frequency bandwidth of 118-512 MHz. The antenna is for applications where a quick set and removal of the antenna is required or where a permanent installation is not possible.

Great care should be taken when handling strong magnetic products. Magnetic mounts may cause painful pinching injuries. When using a magnetically mounted device on a moving vehicle the device may lift off from the vehicle even at moderate speeds in case of collision. Therefore a secondary retention system should always be used to prevent unintentional detachment or loss of the device (the properly tightened feeder cable could possibly be used for this purpose. For maximum grip the surface of the vehicle and the bottom of the magnet should be very dry and clean of dirt, snow, and ice prior to attaching the device.
