I'm looking for a lightweight VHF transmitter rated to very low temperatures, ideally down to -40C. Does anyone know of any transmitters like this? Lotek makes some down to -30C (Ear Tag series), that's the lowest temperature unit I'm aware of.

Thanks,

Jesse

Telonics MK11 and MK12 transmitters specify operation down to -40C. The battery will be a big factor. Most chemistries fail or have degraded performance at temps that low. Their reps will be able to tell you what battery options they have. Cheers.

Hi Jesse, how are you? tricky request, batteries at very low temperatures will consume a lot faster

how big do you need it? a liitle help solution is to make a temperature isolation case and use black epoxy, but it depends on the size and weight that you need on the device.

Usually at -40°C life expentacy can lower down 40%
