rx1m-169-5-12k5

Manufacturer Part Number
rx1m-169-5-12k5
Description
12.5khz Channel 12.5khz Channel Vhf High Power Tx
Manufacturer
Radiometrix Ltd
Datasheet
The ENT1 transmitter modules offer a
100mW RF output VHF data link in
Radiometrix SIL standard pin-out and
footprint. This makes the ENT1 ideally
suited to those low power applications
where
wideband
insufficient range. Together with the
matching LMR1/RX1M receiver a one-
way radio data link can be achieved
over a distance up to 10km+ with
suitable
antennas.
