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.

Good intial service, products arrived safely. Downside, found the products about 50% cheaper at another retailer who are reliable and trusted, so not lower quality and the aerial which was recommended for my area is not suitable and the quality of reception is worse then the original aerial.

I needed a custom size aerial tube bent. Blake were quick off the mark to give a quote (very reasonable) and after paying, I had the finished item a few days later by courier. Excellent service, and the finished tube was accurately bent to the drawing.
