Band-Selective Combiner/Splitters

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.

Features

νLow in-band insertion loss.

νHigh rejection of unwanted bands.

νIdeal for both digital and analogue applications.

νPower-pass to the higher or highest frequency band input.

νRobust 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.
