ELT's are manditory in most countries now.

Also the monitoring Cospass-Sarsat satellites will not find you with a
121.5Mz ELT as they don't monitor it anyymore. You'd better hope for a
nearby commercial aircraft that's monitoring 121.5 - it's about your
only chance now days.

The 406Mz system is also lots more accurate for position determination,
and, the beacons must be registered (registration of 121.5Mz devices was
never manditory).


Hi, User posting as Dave,

do you know how to relate emission frequency
to the length of a corresponding quarter wave whip?
