Product Description
Triple Filtered VHF/UHF Diplexer with DC Pass
The BLACOM21VU is a masthead diplexer designed to combine and separate signals across VHF (85–230MHz) and UHF (470–694MHz) frequency bands. Triple filtered to block out 5G, 4G, and TETRA interference, it supports clear signal delivery for installations requiring both DAB/FM and TV UHF signals.
Built with fully screened construction, this unit offers low insertion loss and strong return loss performance, maintaining signal strength and reducing unwanted reflections. The UHF port features DC power pass (12V/100mA), allowing support for masthead amplifiers or external devices. It is compatible with coax and fibre IRS systems and is optimised for use as the fifth cable in 5-core IRS setups.
The compact housing includes F-type connectors, wall mounting lugs, foam-sealed cable entry glands, and a 90° wide-opening door for simple installation. An earth tag is also provided for system equipotential bonding where required.

Applications
The BLACOM21VU is ideal for combining TV and DAB/FM signals onto a single drop cable, particularly in IRS systems using a 5-core setup. Compatible with any UHF aerial and recommended for use with the Blake DFMO antenna, it simplifies signal routing in both coaxial and fibre IRS environments.

Had to ring to see why I hadn't received my order, was told one item was out of stock, said they didn't know when they would receive the item but that same day it was sent to the courier, then still took another four days before I received my package,very poor packaging,hard to get into, one pole badly scratched and the other has a sticker on it that I cannot remove.
