Frequency Allocation
A.
Application
1)
This section addresses the 406.0 - 406.1 MHz transmitter frequencies which are assigned to the distress
frequency band.
B.
Discussion
1)
The product identification label on each ELT specifies the transmission frequencies of the individual ELT. The
ARTEX ELT 1000 transmits a frequency of 406.040 MHz. Allocation of frequencies, based on beacon population
per specified frequency band, is controlled by COSPAS-SARSAT.
2)
The frequency references throughout this manual for the 406 MHz component should be considered the
baseline and the specific frequency indicated on the ELT product label should be substituted.
