Dual Headend LNB Amp/Power Supply Model 5224IFD
|
Models 5216IFD and 5224IFD are dual polarization headend LNB amplifiers with an LNB powering 117 VAC power supply. These units are designed to drive dual polarization IF distribution networks. They may also be used as dual high level line extenders in cases where 117 VAC power is available. Applications include Multiple Dwelling Units, TV showrooms and offices.
Most distribution networks will be of either the home-run type involving a network of splitters at the headend; or the tapped-trunk type which use taps placed along the two trunk cables. Some systems will use a combination of these two distribution network types. Channel Master carries a wide range of satellite IF 2, 4 and 8-way splitters and taps. Channel Master also carries a range of muitiswitch taps. When used as a line extender with careful system design, it may be cascaded for use with very long cable runs such as in a shopping mall.
DC power is provided at the input connections to the unit; +18V at input A (LHCP) and +13V at input B (RHCP). This voltage is ideal for powering voltage switched LNBs. When DC power is not required at the input, Model 7264 DC block should be added. The outputs are DC blocked.
