SB-2C, SI-2C & AI-2C |
These units are designed for collar attachment to birds such as parrots or macaws with strong aggressive bills. These units can also be used on small & medium sized mammals who require a stronger transmitter casing than our normal epoxy coating.
Frequency Range: 138 to 235 MHz.
Transmitter: SB-2C: Crystal controlled two-stage design, pulsed by
a multivibrator.
SI-2C & AI-2C: Crystal controlled two-stage design, pulsed by
a CMOS multivibrator.
Pulse Width & Rate: SB-2C: Pulse width 20-23 ms, pulse rate nominal 0.67 p/s (40 p/m).
SI-2C: Pulse width 22-24 ms, pulse rate nominal 0.7 p/s (42 p/m).
AI-2C: Pulse width 25-30 ms, pulse rate nominal 0.7 p/s (42 p/m).

Power Output: Set to use available battery power over the required transmitter life.
Housing: The battery and transmitter are hermetically sealed in a brass case.
Antenna: SB-2C & SI-2C: Stranded stainless steel cable, covered with a black nylon coating.
Additional layers of shrinkable tubing reinforce the antenna at its base.
AI-2C: Flat brass strip that also forms the collar. Click here for AI-2C attachment instructions.
Activation: Removing an external magnet starts the transmitter. Replacing it stops the transmitter.
