Diamond MAT-50 magnetic ground plane
Magnetic mat to improve the ground plane of HF mobile antennas, 7–50 MHz, 500 W SSB
The Diamond MAT-50 is a magnetic mat that improves the ground plane of HF mobile antennas when the magnetic base is small or insufficient.
Product description
It is placed on a flat surface of the bodywork and connected to the ground of the antenna base with the supplied ring-terminal cable. The strong capacitive coupling between the magnetic material and the sheet metal greatly reduces ground resistance on HF.
