Grounding frequency for 10M and 16M is four times per mile.

Regular bonding to earth along the route is needed so fault currents have a low-impedance path to ground. For routes using 10M and 16M configurations, the guideline specifies grounding points about four times per mile, or roughly every 1/4 mile. This spacing creates multiple parallel grounding paths, keeps the ground potential and fault-impedance within safe limits, and helps ensure quick dissipation of surges. Placing ground points more often adds cost without extra safety benefit, while placing them less often can raise impedance and risk equipment damage during faults. So four times per mile is the standard spacing for these configurations.
