	HALO digital SFN repeaters fill the gaps and optimise DVB network coverage The HALO series of digital SFN repeaters features a state-of-the-art echo canceller to guarantee optimised transmission and extremely low degredation in signal quality. Automatic mode detection allows the entire SFN network cell to be switched instantaneously. Compact designs up to 100 W rms, an output power range up to 200 W rms and no required measurement during installation makes HALO an unbeatable solution for rapid gap-filling and digital network optimisation. the Elti advantage Fully compliant with EN 300 744 (DVB-T) and EN 302 304 (DVB-H) LDMOS technology State-of-the-art Echo canceller, loop interference is completely removed High flexibility with dynamic transmitted power level Adoptable to channel characteristic changes with real time channel estimation No need for GPS receiver Diagnostics for monitoring the quality of transmission and the status of the equipment Plug and play installation with automatic mode detection and synchronization Low signal quality degradation High signal quality with pre-correction included Remote management and control via LCD, TCP/IP, HTTP and SNMP interface Settings fully adjustable by software Adaptive digital pre-correction and clipping function Compact and highly cost effective Elti®HALO family minimizing total cost of ownership High efficiency for minimizing total operating costs All output power of Elti®HALO are after stated output filter Options for halo SFN repeaters RF output filter in non-critical and critical mask configuration non-critical and critical mask filters UPS for exciter - excellent solution to avoid long time syncronization to GPS satellite after power supply break view technical documentation in PDF; GSM modem - sending SNMP traps over SMS protocol view technical documentation in PDF; Supervising the SFN repeaters on site - use rackmountable computer and rackmountable keyboard view technical documentation in PDF. exciter/compact version The exciter is housed in a compact 19” 3U rack mount and with the A class amplifier provides 5 W of UHF output power or 100 W of UHF output power in compact 19” 4U rack mount. The built-in state-of-the-art echo canceller guarantees optimized transmission and extremely low degradation in signal quality. power amplifier External amplifiers is available in model supplying 250 W rms of output power. All amplifiers are designed for broadband and employ LDMOS technology to guarantee linearity, compact design and high efficiency. Self-protection circuits assures continuous operation and uninterrupted service to the whole SFN repeater. Housed in a 19” rackmount complete with power supply, the amplifier ensures the required redundancy. control and monitoring The integrated control unit provides full control over the assembly and additional options/features. Control software EDM (Elti Device Manager) with a user friendly graphic interface comes as standard for all Elti DVB-T and DVB-H products. It features: Control of all parameters related to operation Password protection and access control Measurement and display of power, voltage, current, temperature Alarm Management of machine history Save and restore function Remote software upload The control software offers the same comprehensive functionality whether used locally or remotely via TCP/IP, SNMP or GSM networks. External connections are provided by: Ethernet LAN/WAN for local/network access RS 232 for local access The central control unit allows integration into ELTI ETRC telemetry system or other supervisory systems. It also offers the control of third party equipment and integration into a single system at the transmission site.
