Antenna Check:
A low quality AM Broadcast Radio Receiver or Equivalent Test Equipment should be
used to determine if energy is being transmitted from the Antenna. When the
Antenna of this Radio (tuning dial on any setting) is held about 6 inches from the
activated ELT Antenna, the ELT Aural tone will be heard (see note below). The ELT
must be reset by pressing either the RESET push button located on the ELT Main unit
or the ELT Remote Unit.
Note: This is not a measured check, but it does provide confidence that the Antenna is
radiating with sufficient power to aid search and rescue. The Aircraft’s VHF
Receiver, tuned to 121.5 MHz, may also be used. This Receiver however is more
sensitive and could pick up a weak signal even if the radiating ELT’s Antenna is
disconnected. Thus, it does not check the integrity of the ELT System or provide the
same level of confidence as does an AM Radio.
