Operation modes
Gapfiller
The MOT GAPFILLER receives a DTV signal from the air, filters it, amplifies it and converts it into IF, equalizes it,
cancels it and repeats it using a fully agile local oscillator controlled by GPS to send it back to the air on the same
frequency. This way you can cover areas where the main signal arrives at low levels
Regenerative Transmitter
The MOT GAPFILLER receives a DTV signal from the air, filters it, amplifies it and converts it into IF, equalizes it,
cancels it and repeats it using a fully agile local oscillator controlled by GPS to send it back to the air on another
frequency in any TV band. This system is very simple to install and makes the transmission quality exceptional
although the reception signal is not good.
Transmitter
The MOT GAPFILLER is also a regular digital TV transmitter. It is compact and lightweight, and it is available in 1RU and 2RU sizes. It has air cooling, and its web interface allows remote monitoring of all operating parameters. Additionally, it has ASI and TSoIP inputs. Clients will be able to use it in all standards such as DVB-T/T2, ISDB-T/Tb, DMTB, and ATSC 3.0.
