How long is a 40m vertical antenna?
Normally each 40m radial is about 33 ft. long! As a result of being just two dimensions, this antenna can be installed on a property line, as long as there is no metal fence running along the line below it. In fact a 6 ft.

How high should a 40m dipole be?
Recommendation. For best results, dipoles should be at least 1/2 wavelength above ground level. For the lower bands, especially 160-40 meters, this can become impractical–place your dipole as high as your situation allows.
