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.

Application Notes |
|
1. 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. |
