Why is there no single fixed minimum distance that applies to all amateur HF antenna installations for RF safety compliance?
-
A
Because FCC regulations change too frequently to establish uniform distances
-
B
Because the required distance depends on power, frequency, antenna gain, and duty cycle specific to each installation
-
C
Because all HF amateur stations are categorically excluded from RF exposure evaluations
-
D
Because distance limits apply only to commercial broadcasting stations, not amateurs
