Details

The new family of Signal multiswitches enables the implementation of antenna systems for reception of satellite and terrestrial TV and radio signals in single-family houses as well as small residential and office buildings. The multiswitches are designed to work indoors. Due to star topology, all cables deployed to outlets in the antenna system go from a central node (from a single multiswitch or a group of them). A very high isolation among outputs eliminates the risk of crosstalk between bands and polarizations. The built-in cable characteristics equalization function can compensate the influence of cable attenuation that increases with frequency and cable length.
The switch is equipped with a passive terrestrial TV path, so it is recommended to use antenna preamplifier or amplifier, which will compensate for the attenuation of the multiswitch (12 dB) and passive elements in the installation (cable, outlets, connectors) in the terrestrial TV path. The selection of the amplifier should also take into account the signal level from the transmitter (power and suspension height of the transmitter, distance to the reception point, gain of the antenna, terrain between the transmitter and receiver). An up-to-date list of transmitters can be found at Data of terrestrial TV transmitters in Poland.
The multiswitch is equipped with a 12 V switch in the antenna path. In order to power the amplifier, it should be set to the "On" position. If an amplifier with its own power supply is used, e.g. AWS 1/1 F B1216 (with gain control), leave the switch in the "Off" position.
The supply voltage in the terrestrial antenna path is switched on by moving the switch up
The both voltage indicators, in the power supply unit (PSU) and in the multiswitch, should continuously shine.
If, after connecting the terrestrial antenna and switching on the power supply, the diodes on the power supply and the multiswitch blink, this indicates a short circuit in the terrestrial antenna path. This can be caused by switching on the power in the terrestrial path at the antenna without an amplifier, or by a badly wound connector (short-circuit between the central conductor and the cable shield braid). Immediately switch off the power and remove the cause.
The flashing of the power supply diode is caused by switching on the power supply in the ground path at the antenna without an amplifier or by a bad fitting of the connectors (short circuit between the central conductor and the cable shield braid). Immediately switch off the power and remove the cause.
The concept of passive terrestrial path with power supply option has some advantages:
  • optimise installation cost
  • selecting the most suitable amplifier (gain level, place of installation, separate regulation for VHF and UHF)
  • powering the amplifier from the multiswitch (no separate power supply needed)
The multiswitch distributes signals from one satellite, terrestrial TV and DAB/FM radio to a maximum of four outlets, so it can feed up to four single-tuner satellite receivers. A twin-tuner satellite PVR receiver requires two outputs of the multiswitch. In the case of an unused multiswitch output, it should be terminated with the R66205 75 ohm resistor.
For multi-family buildings, designed for building large SMATV/MATV systems, DIPOL offers multiswitch solutions of MR-5xx, MV-5xx, MR-9xx and MV-9xx series from TERRA. Excellent workmanship, stability of parameters and very low failure rate make these multiswitches recommendable even for the most demanding customers.
