NBFM Multi-channel 500mW UHF Transmitter
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).
