3.3. Pre-Installation Checklist
The CATV Distribution Hub provides a centralized CATV copper twisted pair
cabling solution.
1. The CATV Distribution Hub is always connected to the terrestrial CATV
cable feed within a building. For example it is connected directly to the
output of a CATV head end feeding from equipment such as an RF splitter,
RF amplifier or RF modulator.
2. The CATV Distribution Hub must be used in conjunction with MuxLab’s
passive CATV Baluns (p/n 500006, 500302). The CATV Baluns are
connected at each RF receiver, tuner or cable modem.
3. Don’t cascade Distribution Hub.
3.4. Pre-Installation Tips
1. In a point-to-point scenario for CATV, VHF and FM, cable lengths of up
to 45 meters may be achieved if the nominal input is about 5dBV. If
signal is higher than 10 dBmV, it may be necessary to attenuate the lower
frequency or reduce the signal level in order to avoid over-driving the TV
or modem.
2. When combining an existing signal with a modulated signal, make sure to
have equal signal strength at the point of the combiner so one signal does
not degrade the other.
3. When possible, use the lowest frequencies available for the modulated
channels. Lower frequency channels have lower signal loss on the cable
runs. Don’t drive the cable with more than 10dBmV.
