These units are multiswitch taps designed for cascade use in dual polarization, tapped trunk distribution systems. Each of the tap outputs can select either thru trunk signal depending upon voltage present on the customer cable. 0 to +14V selects one trunk, whereas +16 to +21V selects the other. A typical application would be to serve apartments on each floor of a high-rise multiple dwelling unit with the trunk cables passing down a service shaft.
They are passive and wideband, allowing VHF/UHF as well as satellite IF signals to pass. An input directional coupler on models 6222IFD and 6254IFD gives very low thru loss and allows DC to pass along the trunk. They should be used in conjunction with a satellite IF headend distribution amplifier such as the Channel Master Model 5216IFD or 5224IFD. The units are cascaded along the two trunk cables as far as system losses allow. The terminating models should be used as the final device in a cascade.
When signal attenuation by the cable and thru losses makes signal levels too low to be useful, it is possible to extend the two trunk lines by inserting a 5217IFD line extender. The 5217IFD should be powered by an 8002IFD power supply. When amplification is required along the trunk line, it is not generally possible to pass VHF/UHF signals on the same cables.
Normally, the lowest tap output level will be from the tap just prior to the final, terminating tap. Calculations are based on the ouput of that tap at the highest frequency (usually 1450 MHz in the US, 1750 MHz in Latin America).
LNB output level -35 dBm per transponder (typical)
Minimum customer level -55 dBm per transponder
Therefore, maximum distribution loss = 20 dB
Considering Customer #6
Cable loss between dish and Tap #3 = a dB
Cable loss from Tap #3 to customer = b dB
Thru loss, Taps 1 and 2 = c dB
Tap loss, Tap 3 = d dB
Headend amplifier gain = e dB
Then a+b+c+d-e must be less than 20 dB.
In this example, c=4, d=17, e=16 or 24.
Satellite IF and VHF/UHF High Level Distribution Headend
Use in dual polarization networks and with multiswitch taps.
When satellite IF and VHF/UHF signals are distributed on the same cable, they must be separated at the customer's location using a 4001IFD diplexer. The diplexer's satellite output is then connected to the IRD satellite IF input, and the diplexer's VHF/UHF output is connected to the satellite receiver's VHF/UHF input.
For a variety of VHF/UHF distribution ampilfiers, request the Channel Master@ MATV Catalog.
