One reason for the 120 radial ground system on broadcast sticks often over-looked is that a large number of radials below grade makes the system more stable over seasons between dry and wet wx. It may not matter as much for ham but many radials causes the Z to settle down or not vary as widely between dry and wet earth. This does not relieve hams from the need for a lot of radials on or below the ground; at least 60 is needed and no reason to not shoot for 90 short ones close in if room is limited.
