I carry one beacon on my chest, one on my back (reverse the harness), one in each pocket, and if when I'm racing ski-mo, I shove it up my ass to keep it close to my center of gravity and cut down on wind resistance.

Wear my PIEPS with the harness, beneath the sternum squeezed between hip- and chestbelt of backpack. It's bit uncomfortable to bow down and strap in, but wile hiking or riding I'm unaware of it. I dont mind the comfort, but problem with that spot is more, that I'd like to have my mobile somewhere accessible but the only 30cm away zone is in the backpack...
I've hard times to imagine why it wouldn't also be ok to have the beacon in an airbag-backpack (with an additional butt belt) or in a jacket pocket under that airbag... but some things you do cos "you do it like that", without a better reason.
Beacons only are affected in search mode. The effect dissipates really quickly with distance. Barkhausen himself says, "to get rid of any perceived interference all you need to do is hold your searching transceiver a full arm’s length from your body." This renders most (but not all) discussion about placement of cell in relation to beacon moot. p.s. Spark plugs from a snowsled (or car) wreak havoc on beacons, so search on foot. p.p.s. Manufacturers say 30 cm. Barkhausen says 40 cm. I've read as high as 60 cm. Play with your beacon, trying to confuse it (in a car, inside, near a computer/TV); you'll get a feel for interference and how far you need to hold it.
