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  
acombinedfeedfromadistributionamplifierorsystemtofeedseparateoutletsFig. 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.
