Harmonic Distance to Protected RAS / Science Bands

Compact by default: the table starts with the protected band, a short allocation code, and the harmonic-distance columns. Turn on extra regulatory details only when you need them.

Allocation code: P = primary, S = secondary, — = no explicit entry shown in this compact summary. The short code is listed as R1 / R2 / R3. For example, P / P / S means primary in Regions 1 and 2, secondary in Region 3.

overlap / distance = 0 near (0 to 5 MHz) caution (5 to 20 MHz) farther than 20 MHz

Distances are computed in MHz internally, then displayed in the most appropriate unit. RA.769 values are shown only where they were already available in the compiled dataset.
