RI-2A |
This unit is designed for aggressive raptors (such as spotted owls) where a durable back-pack is required. It is designed to present a very low profile and has a very rugged antenna and anchoring system.
Frequency Range: 138 to 235 MHz.
Transmitter: Crystal controlled two-stage design, pulsed by a CMOS multivibrator.
Pulse Width & Rate: 20 to 30 ms, nominal 0.7 p/s (42 p/m).
Specifications:| Model | Weight | Nominal Life | Lifespan range | Dimensions: LxWxH (mm) |
| RI-2A | 8g | 6 months | 3-9 months | 50 x 25 x5 |
| RI-2A | 12g | 12 months | 9-18 months | 50 x 25 x 7 |
| RI-2A | 17g | 24 months | 18-30 months | 50 x 25 x9 |
Housing: The battery and transmitter are encapsulated in an inert waterproof epoxy.
Antenna: Stranded stainless steel cable covered with a black nylon coating. Two layers of shrinkable tubing reinforce the antenna at its base.
Activation: Removing an external magnet starts the transmitter. Replacing it stops the transmitter.
Activity (suffix "A"): Every motion event exceeding a preset range of angles generates one extra pulse between the normal pulses. This activity pulse is distinctively shorter (~12 ms) than the normal pulses. This option adds ~0.5g to the finished weight of each transmitter.
Position (suffix "P"): The pulse rate switches from ~24 p/m to ~50 p/m when the animal changes body position, pivoting the transmitter 10° or more from a preset orientation. This option adds ~0.5g to the finished weight of each transmitter.
