TERRA - F1 among multiswitches
At SatKrak exhibition there were granted annual awards for the best products of the year. The voting included the votes of Internet users. The Best Product in multiswitch category became TERRA multiswitches, professional-grade equipment. The multiswitches are designed for large and complex installations in housing developments as well as for demanding individual users (in larger one-family houses and other buildings). Due to high quality, reliability, easy installation and maintenance-free operation, they are really great products. The multiswitches are widely used in SMATV systems up to 1000 outlets.

Main features:
- best on the market and stable modulation error rate (MER) for SAT signals,
- excellent isolation between inputs and between outputs (min. 30 dB, typ. 45 dB),
- flexible power options - versions with built-in power supply or for supplying from a central power supply,
- low power consumption does not generate much heat, which extends the life of the equipment,
- the manufacturer offers a free SatNet program that allows to design more complex installations.
What does the TERRA multiswitch offer include?
DIPOL sells full range of these devices, both in the case of cascadable and radial multiswitches. They allow to receive broadcasts from 1, 2, 3, or four satellites. There are available passive and active models, with local or remote power supply. With the use of additional equipment we offer (splitters), the designers can create advanced and flexible multipoint SMATV systems. Central power system in multiswitch installations. Modern multiswitch installations should be powered from the main source of electrical power. This approach helps to build the installation, because one does not need to supply AC voltage (230 VAC in Europe) to each box in which there is a multiswitch. Reputable manufacturers of multiswitches take into account this type of power supply in their products. In the case of TERRA, MSV-5xx multiswitches are centrally powered from the power supply integrated with SA-501 amplifier, whereas MSV-9xx multiswitches take power from SA-901 amplifier. In both cases the power is supplied through H lines. Building an installation based on MSV multiswitches, it is necessary to balance the power requirements with maximum current capacity of the supplying device/s. For example, using SA-901 amplifier with max current of 2 A, with two LNBs consuming 2x300 mA there is 1.4 A left for the rest of the installation (2 A - 2*0.3 A = 1.4 A), so the SA-901 device can power up to 14 MSV multiswitches (each consuming about 100 mA). www.dipolnet.com
