12.5kHz Channel VHF High Power TX

Frequency:Standard: 169.44375MHz & 169.40625MHz

The ENT1 transmitter modules offer a 100mW RF output VHF data link in Radiometrix SIL standard pin-out and footprint.

ENT1 ideally suited to those low power applications where existing narrow band and wideband transmitters provide insufficient range or where a 12.5kHz channel spacing is required. Together with the matching ENR1 receiver a one-way radio data link can be achieved over a distance of up to 10km+ with suitable choice of data rate and antennas.
