Hello,
a big name in the antenna manufacturer say in the brochure of their vertical
antenna: "minimum recommended radial requirements: at ground level, 8
radials of 0,1 wl each calculating the lowest operational frequency. Above
ground, 2 radial cut for the specific frequency for each band of operation."

Assuming a operational frequency e.g. 7 MHz, at what height from the ground
one can consider the antenna mounted "above ground" ??

TIA and 73,
