Photograph of a Burmese python showing the GPS antenna exiting through the skin. GPS signal attenuates under the skin, and therefore, these tags must have an external antenna, potentially compromising the animal’s health and tag retention. The large, bulbous antenna is the GPS antenna, and the thin wire is the UHF remote download antenna
