INSTALLATION INSTRUCTIONS
These masthead and general-purpose passive products are used for combining or splitting
signals in the VHF/FM, UHF and satellite IF frequency bands with a minimum of insertion
loss. The units are fully-screened and are easy to install, both indoors and outdoors. The use
of ‘F’ connectors allows their use with a wide range of cable sizes.

proCOM21VU is a two-band passive combiner/splitter (diplexer) for combining or splitting
signals in Band II (VHF/FM) and Bands IV-V (UHF). Typical applications include combining
signals from VHF/FM and UHF antennas onto a single downlead cable – Fig. 1 – or splitting
acombinedfeedfromadistributionamplifierorsystemtofeedseparateoutlets–Fig. 2. This
unit will pass line-power between the common and UHF ports, allowing a masthead
preamplifier to be used on the UHF antenna if necessary – Fig. 3.
proCOM31VUS is a 3-band passive combiner/splitter (triplexer) for combining or splitting
signals in Band II (VHF/FM), Bands IV-V (UHF) and the satellite IF band (SAT). The very high
rejection on the SAT port in the FM and UHF bands allows this unit to be used to combine
the output of a satellite LNB with VHF and UHF terrestrial antennas – Fig. 4. High isolation
is required in this application to prevent wideband amplified noise present on the output
oftheLNBfromdegradingtheVHFandUHFsignals. TheproCOM31VUSpassesline-power
between the common and SAT ports, allowing LNB power and 22 kHz tone or DiSEqC
controls to function normally.
