DIAMOND MAT50
Magnetic sheet for optimizing car antenna ground plane
For mobile HF operation, a reliable ground plane is needed. This is difficult when using a small or insufficient magnetic mount.
The problem can be solved with Diamond's new magnetic mat. Simply place the mat on a flat surface on the car and connect the included ring cable to the antenna's ground base. Thanks to the superior capacitive coupling between the magnetic material and the chassis, HF conduction resistance is significantly reduced. When operating at 3.5 MHz, two of these mats are recommended. At 50 MHz, the connecting cable should be as short as possible (less than 20 cm).
