FM IBOC Solutions. Mega Industries offers HD Radio combiners or injector solutions to the FM broadcast community. These units are factory tuned to provide maximum isolation while reducing out of band spurious signals.
HD Radio Combiner/Injector
Mega Industries High Level HD Radio Combiner/Injector is designed to allow minimal down time during installation. It’s straight through Digital Combiner Line construction allows for installation in place of a straight section of transmission line. Rugged yet lightweight aluminum construction results in a combiner which is comparable in weight to the copper line being replaced.

IBOC Switchless Combiners
Mega Industries FM Switchless Combiner systems utilize the latest state of the art drive systems to provide precision control and seamless operation. With this system the broadcaster is assured of an uninterrupted signal and smooth operational changes that can be made under full power conditions.
The Mega Switchless Combiner design allows balancing and switching between transmitters in infinitely variable ratios that can be finely adjusted in the field to attain the signal power levels necessary for even the most signal mixing scenarios.
Every system is tuned and optimized during manufacture to provide the absolute maximum isolation possible while also reducing out of band spurious signals.
Mode control and signal feedback is provided via dry contact switch closures.
Coupling ratios between 3dB and 12dB deliver a broader array or tools to employ when designing the complex systems demanded in today’s ever more tightly constrained applications.
