Masthead A/B Combiner With Switchable Power-Pass on Both Legs

Masthead A/B Combiner With Switchable Power-Pass on Both Legs

The BLACOM21AB is a high-performance A/B masthead combiner designed to merge TV signals from Group A (470–606MHz) and Group B (616–694MHz) transmitters. Triple filtered to minimise interference from TETRA, 4G, and 5G signals, it helps maintain clear and reliable reception.

This unit is ideal for use in areas where both Group A and Group B transmitters are needed. By combining signals from two aerials into one, it removes the need for multiple systems and allows access to a broader range of channels. It supports masthead amplifiers with a switchable power pass on both legs and offers low signal loss of just 2dB within each group.

Built for outdoor use, the housing features a weatherproof design with foam-sealed cable glands, a 90° wide-opening door, and an earth tag. F-type connectors ensure stable signal transmission, and the included mounting options support both mast and wall installation.

The BLACOM21AB is suited to installations in areas with overlapping transmitter coverage. It allows for a simplified setup using two aerials to receive a full range of TV channels across both groups. By combining signals into a single feed, it reduces equipment and supports consistent reception in complex broadcast environments.
