Used in the Eighties in the Naval Aviation, it has a microphone.
The antenna is flexible and is rolled up in the plastic handle.
The powering starts as soon as one withdraws the known fixed pin
there handle.  The power supply is separate (rectangular pile with lithium).
It is not used any more today.
