Number of Antennae

ortovox_3_plus_blue_1
Many modern avalanche transceivers these days feature three antennas, like the Ortovox 3+ here.

Antennae are the little thinga-majigs inside transceivers that transmit and receive signals to and from other beacons. Most newer models that have multiple antennae will be able to electronically choose the best one to use automatically because as we mentioned earlier, signal strength depends on relative antennae orientation between transmitter and receiver. As a general rule of thumb, the more antennae there are, the better.
