INSTALLATION INSTRUCTIONS
These masthead and general-purpose passive products are used for combining or splitting
signals in the VHF/FM, UHF and satellite IF frequenc bands with a minimum of insertion
loss. The units are full -screened and are eas to install, both indoors and outdoors. The use
of F connectors allows their use with a wide range of cable sizes.
Features
nLow in-band insertion loss.
nHigh rejection of unwanted bands.
nIdeal for both digital and analogue applications.
nPower-pass to the higher or highest frequenc band input.
nRobust diecast housings, suitable for outdoor (masthead) and indoor use.
Application examples
proCOM21VU is a two-band passive combiner/splitter (diplexer) for combining or splitting
signals in Band II (VHF/FM) and Bands IV-V (UHF). T pical applications include combining
signals from VHF/FM and UHF antennas onto a single downlead cable  Fig. 1  or splitting
a combined feed from a distribution amplifier or s stem to feed separate outlets  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 necessar  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 ver 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
of the LNB from degrading the VHF and UHF signals. The proCOM31VUS passes line-power
between the common and SAT ports, allowing LNB power and 22 kHz tone or DiSEqC
controls to function normall .

Signal connections
To preserve RF screening integrit the signal connections to the amplifier should be made
using good qualit coaxial cable and connectors. This is particularl important with DTT to
minimise the ingress of impulsive electrical interference. The use of cable benchmarked
under the CAI scheme is recommended.
Crimp F connectors, used in accordance with the manufacturers instructions, will give the
best results. The importance of achieving sound braid connections cannot be over-stressed.
System earth bonding
Earth bonding terminals are provided on the amplifier castings for use where necessar .
Distribution s stems suppl ing signals to more than one household should compl with the
safet requirements of BS EN 50083-1. This effectivel requires the s stem to be earth
bonded. (The use of isolated outlet plates is no longer recommended since the compromise
screening integrit and allow ingress of interference.)
Fixing
Methods for mounting the amplifier are illustrated in Figs. 5 to 7. The cable tie fixing is
intended to support the weight of the amplifier onl . Cables should be taped to the mast at
intervals of approximatel 400 mm to ensure that their weight is adequatel supported.
Being full screened, these amplifiers will not be affected b proximit to antennas. However
clearance of not less than 300 mm from the nearest part of an antenna should be observed
to avoid degrading the antennas performance.
