Band-Selective Combiner/Splitters
2
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.
Features
n Low in-band insertion loss.
n High rejection of unwanted bands.
n Ideal for both digital and analogue applications.
n Power-pass to the higher or highest frequency band input.
n Robust 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). Typical 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 system 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 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
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 normally.

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 only. Cables should be taped to the mast at
intervals of approximately 400 mm to ensure that their weight is adequately supported.
Being fully screened, these amplifiers will not be affected by proximity to antennas. However
clearance of not less than 300 mm from the nearest part of an antenna should be observed
to avoid degrading the antennas performance.

Note: a preamplifier cannot be powered via the proCOM31VUS since there is no line-power
pass to the UHF port.

Signal connections
To preserve RF screening integrity the signal connections to the amplifier should be made
using good quality coaxial cable and connectors. This is particularly 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 manufacturers 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 necessary.
Distribution systems supplying signals to more than one household should comply with the
safety requirements of BS EN 50083-1. This effectively requires the system to be earth
bonded. (The use of isolated outlet plates is no longer recommended since they compromise
screening integrity and allow ingress of interference.)
