Modern multiswitch installations – Signal MRP

Signal MRP multiswitches with passive DVB-T/DAB/FM path have been designed for small/medium size SAT installations built in star topology. One device or a group of such multiswitches feeds the subscriber outlets from individual outputs of the multiswitch(es). This topology is typical for applications in single-family homes and in buildings inhabited by several or so families.

The MRP series has passive terrestrial path. If the terrestrial signals in the location of the terrestrial antenna(s) are not strong enough, it will be necessary to use an antenna preamplifier, or even a high gain outdoor amplifier such as MA080L R82022.

The configuration with the MA080L R82022 amplifier allows for adjustment of the gain in a wide range for each band: 20 dB for FM and VHF, 30 dB for UHF.
Other band/broadband amplifiers for use in the terrestrial path
Broadband amplifiers in terrestrial paths of multiswitch systems amplify the signals received by antennas to ensure proper levels in all outlets. It includes the compensation of losses on passive network elements (cabling, splitters, outlets). The amplifiers have one broadband input or several band inputs with individual gain adjustment and a broadband output. They usually ensure compensation of the attenuation of the cabling, changing with frequency, and are equipped with power supplies. The amplifiers are characterized by high maximum output levels of over 100 dBμV.

Video from security cameras in antenna installation
To convert an audio/video signal from a source like a PC, video player, or surveillance camera into RF signal distributable in the antenna system, it is necessary to employ an RF modulator. Digital TV modulators are equipped with one or more HDMI input(s) and RF output that injects the signal to the installation in the form of a TV channel that can be received by any television connected to the antenna system.
HDMI to DVB-T encoder/modulator R86700 encodes and modulates Full HD (1920x1080-60p) signal provided to its HDMI input to RF signal in accordance with DVB-T standard (COFDM). This way, the device can distribute the surveillance video from the output of a DVR/NVR to multiple televisions, via typical coaxial cabling used in antenna systems, which also can make a good alternative for applications distributing the video with the use of HDMI splitters and cables.

The Signal R86700 modulator converts the Full HD signal from the HDMI output of the DVR into a DVB-T channel. The A2670, A0710, and A0221 antennas (example) are connected to the inputs of the masthead antenna amplifier Terra MA080L R82022. Each path ( FM: 88-108 MHz, VHFIII: 174-230 MHz, and UHF: 470-790 MHz) has a separate gain adjustment, the UHF path also has built-in LTE 800 filter. The MRP-508 R68508 multiswitch distributes the satellite signals from the A98257 QUATRO LNB and the amplified terrestrial DVB-T and FM/DAB signals to eight subscriber terminal outlets Signal R694100. The signals from the antennas and from the modulator are combined by the RI-2/1 F E2094 FM/TV 2-way splitter. The MRP-508 R68508 multiswitch provides 12 VDC voltage that goes through the DC pass-through path of the splitter to the MA080L R82022 amplifier.
