I recommend everyone should have one. They can be a life saver anywhere, anytime, for boat, light aircraft, motorhome. The older style transmitted, once activated on 121.5 MHZ. All airline aircraft, domestic and international monitored that frequency when operating over Australia. The latest units transmitting on 406 MHZ are monitored by satellite and can pinpoint your position within a meter or two, and search and rescue is immediately initiated. As they say in the American Express advert. "Don't leave home without it"...

Hi Phil. Not really familiar with the Sarbe Beakon. Have a look at this website for GME. This is the brand I have but can't tell you much more coz I'm presently overseas.

No Phil.  Sarbe's were short range 243mHZ beacons for SAR purposes,,, we used em in marine section and homed in on them in SAREX's, as the choppers and hercs.

It appears SARBE beacons are still in production. They are part of the family of distress or locator beacons that operate on the international distress frequencies.  As far as I can recall most the older ones radiated on 121.5 and 243 MHz simultaneously (note the harmonic relationship.) The 121.5 signals were monitored by civil aircraft and the 243 by military aircraft. The 243  MHz signal is in the so called military UHF band.  For more on the subject see - http://en.wikipedia.org/wiki/Distress_radiobeacon#History.

There is a long history of survival radio equipment pre the international 121.5/243/406 MHz see - http://en.wikipedia.org/wiki/Survival_radio. How many of you worked on the old Gibson Girl?

Miitary SARBE's that I used didn't transmit on 121.5mHz (and yes sometimes you get a harmonic) but the idea is  if a downed pilot ie Vietnam era on wards set off a SARBE we didn't wan't anyone in a civil aircraft being able to pick up the signal, we wnted out friendly military ONLY to pick up the signal.

SARBE is a generic name only and can mean many things in different parts of the world.

Signals are.s now are much more sophisticated and encription is readily available these days.
