ENT1
12.5kHz Channel VHF High Power TX
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 existing narrow band and
wideband transmitters provide
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 choice of data rate and
antennas.
