LB-2N & LB-2 |
The LB-2N and LB-2 are designed for glue-on attachment to small bats, small birds and large insects. The light weight of these transmitters now permit the radiotracking of smaller species than previously possible. The quoted weight is the total weight of the finished encapsulated transmitter, antenna and battery, ready to use in the field.

Frequency Range:LB2: 138 to 235 MHz. LB-2N: 148-151, 164, 165, 172 & 173 MHz only.
Transmitter: Crystal controlled two-stage design, pulsed by a multivibrator.
Pulse Width & Rate: Pulse width 20 ms ± 10%; pulse rate nominal 0.67 p/s (40 p/m).
Specifications: (* = model shown above)| Model | Weight | Nominal Life | Lifespan range | Dimensions LxWxH (mm) |
| LB-2N | 0.31g | 7 days | 3-7 days | 11.5 x 5.3 x 2.8 |
| LB-2N* | 0.35g | 12 days | 8-15 days | 11.5 x 5.3 x 2.8 |
| LB-2N | 0.42g | 21 days | 13-22 days | 11.5 x 5.3 x 2.8 |
| LB-2* | 0.47g | 12 days | 8-15 days | 13 x 6.5 x 3.5 |
| LB-2* | 0.52g | 21 days | 13-22 days | 13 x 6.5 x 3.5 |
Housing: The transmitter and battery are encapsulated in an inert waterproof epoxy. Although the unit is usually glued to the animal (click here for gluing instructions), one tube can be attached for the passage of harness material or a suture. A tube will increase the total weight by ~0.05g.
Antenna: Single stainless steel wire, 0.007" (0.18mm) in diameter or a stranded stainless steel wire covered with black nylon coating (0.52g LB-2 only).
Activation: Soldering two wires starts the transmitter. Activation Instructions
Position (suffix "P"): The pulse rate switches from ~24 p/m in a vertical position to ~50 p/m in a horizontal position. This option adds ~0.5g to the finished weight of the transmitter.
