TLM2

NBFM Multi-channel 500mW UHF Transmitter

Frequency:458.525 - 459.1MHz, 458.8 - 461.3MHz

The TLM2 transmitter module offers a 500mW RF output in the UK 458MHz. This unit is ideally suited to applications where existing lower powered transmitters provide insufficient range. The TLM2 transmitter is a multi-channel, narrowband design, suitable for licensed and unlicensed UHF allocations. Together with a matching LMR2 receiver a one-way radio data link can be achieved over a distance of well over 5km (with a suitable antenna).
