Is one allowed to use an #antenna with a flat ground plane for #LowFER in the US? #Part15 specifies 49ft as the total length of the antenna, feed line, and "ground lead", but it doesn't say anything about using a flat ground plane. Or would they consider the maximum measurement of the ground plane as the length of the ground lead?

#HamRadio (even though it's technically not)

Where are all the #LowFER s?
