Titley Scientific’s LT5 and LT6 are tiny single stage transmitters suitable for monitoring the smallest of animals including bats.
Manufactured on printed circuit board, the transmitters range in size from under 470mg (complete with battery and antenna) with a useful life of 25 days, to 1.5g with a useful life of 3-4 months, possibly longer depending on battery. Standard pulse rate is 55 pulses per minute.
The lightest transmitter is activated by cutting a protruding wire loop. Reed switch models are slightly heavier and are activated by a magnetic switch.
Our more commonly used glue-on transmitters are especially suitable for bats, small birds and insects. They can also optionally be fitted with cable ties for use as collars on small mammals, or with tubes for harnesses, which can be useful for animals such as frogs, at a slight increase in weight.
Useful for Small Mammals, Birds, Reptiles, Amphibians, Fish and Insects.
| Attachment: | Glue-on (lightest), harness, collar, implant |
| Frequency Bands: | 138MHz, 148-152MHz, 173MHz, 216-220MHz. |
| Weight LT5: | 570mg (minimum, encapsulated, with reed switch and heavy duty antenna). |
| Weight LT6: | 470mg (minimum, encapsulated, no magnetic reed switch). |
| Dimensions: | From 17 x 8 x 4 mm (LT5). Whip Antenna Length = 150mm From 9 x 5.5 x 3 mm (LT6). Whip Antenna Length = 150mm |
| Pulse rate: | 55 PPM standard (others, please enquire). |
| Pulse Duration: | 10ms standard (others, please enquire). |
| Antenna: | Typically whip antenna of stranded ss wire, can be customised. |
| Antenna Length: | 150 mm (standard). |
| Operating life: | 25 Days (Nominal) with 337 Battery. |
| Operating Temperature Range: | -20 DegsC to +60 DegsC. |
| Carrier Frequency Stability vs Temperature: | ±15 ppm (parts per million). |
