ARX digital repeaters for complete restoration, as the DVB signal is received and re-transmittedThe ARX series of regenerative digital repeaters features built-in error correction via the intelligent COFDM modulator that provides error-free retransmission of multi frequency DVB networks. The error-corrected transport stream is also available via ASI output for local re-multiplexing, or monitoring purposes. The modulator allows the repeater to function as a transmitter. Low power applications are available in compact designs up to 100 W rms; the range of LDMOS power amplifiers offers scalable solutions up to 10 kW rms, as air cooled or liquid cooled repeaters. the Elti advantage- Fully compliant with EN 300 744 (DVB-T), EN 302 755 (DVB-T2) and EN 302 304 (DVB-H)

- Based on the same platform with the same performances as Elti digital transmitters SKY®.
Options for arx repeatersexciter The exciter is housed in a compact 19” 3U rack mount and with the A class amplifier provides 5 W of UHF output power (0.1 W for VHF). The high sensitivity input tuner provides optimized reception of the RF DVB signal. The DVB signal is completely demodulated to MPEG-2 or MPEG-4 TS and error-corrected before retransmission in a fresh COFDM spectrum. Errorcorrected MPEG-2 or MPEG-4 TS is available via ASI output for local re-multiplexing. ASI input allows the repeater to function also as a transmitter. Other functions and performances are the same as for Elti digital transmitters SKY®. power amplifierExternal amplifiers are available from Elti digital transmitters SKY®. compact repeatersThe compact repeater includes the RF down-converter, exciter functions, the power amplifier and output filter internally. It is available in a compact 19” 3U rack mount and with the A class amplifier provides up to 5 W of UHF output power or in compact 19” 4U rack mount with the AB class amplifier that provides up to 150 W of UHF output power (300 W for VHF).liquid cooled solutionsRefer to liquid cooling solutions for Elti digital transmitters SKY®.
