Wireless telemetry system at bear den. The insertable cardiac monitor (ICM) communicated with a relay station housed in a waterproof container via an antenna buried under the bear. Transmissions to an internet site were via a cellular module attached to a timber tripod fabricated at the site. The system was powered by 12 volt batteries charged by a solar panel.
