Traditional very-high-frequency (VHF) vaginal implant transmitters (top) and radio-linked transmitter (rVIT; below). Note the secondary black antenna allowing pairing of the rVIT and the GPS collar via ultra-high-frequency (UHF) radio signal. Both transmitters are 7.5 cm in length from the wings to the end of the housing, 1.5-cm diameter, and the wings are 6.5-cm wide. The VHF antenna on both transmitters is 9.5 cm, for a total transmitter length of 17 cm, and the black UHF antenna on the rVIT is 8.5-cm long
