IMPORTANT: If storing a VHF collar for a long period of time, turn it on for 12 to
24 hours once every four months. This will exercise the battery and minimize
passivation.
Water resistance: VHF collars are designed for terrestrial mammals. VHF collars
are waterproof and have been tested in water to a depth of two metres for 24
hours.
Durability: VHF collars are designed for normal wear and tear. Normal wear and
tear does not include, for example, being chewed excessively by animals, vehicle
strike and electrocution.
Replacements: Because of the variance in operating conditions, Lotek
recommends that VHF collars be replaced between 80 to 90 percent of their
calculated life. For information about the VHF collar’s calculated life, please refer
to the order summary.

VHF Receivers
Lotek recommends using dedicated wildlife VHF receivers. Wideband receivers
are not recommended.
1.6.
VHF Antennas
Lotek recommends Yagi antennas. Three-element folding Yagi antennas can be
purchased through Lotek.
NOTE: Ensure that your VHF receiver and VHF antenna operate in the same
frequency band as the collar’s VHF transmitter.
