COM-TECH designs and manufactures a comprehensive range of output channel Combiners for analog and digital Broadcast TV and Radio applications. COM-TECH Combiners are available for all the Operating Bands, with a wide choice of Cavity Sizes, with different Numbers of Poles, allow Adjacent-Channel/Block Combination, and make use of different Combination Techniques:

  • Manifold
  • Starpoint
  • Balanced
  • Stretchline (providable upon request)


COM-TECH Combiners Coding is based on.

Series MX, SP, DB …
No. Of Poles 4, 6, 8 …
Technique E: Cross Coupling, X: XLineD: DualCross
P: All-Pole, N: 2-Notch
Cavity Size 60, 80 …
Operating Band C: UHF, B: VHF B.III, A: VHF B.I-II

COM-TECH Combiners make use of innovative and proprietary design techniques:

  • XLine: Extracted-Pole Elliptical-Response
  • DualCross: Double Cross-Coupling
  • MultiStep: Ultra-Flat Frequency Response
  • SIR
  • Hairpin
  • EVA-Mode


COM-TECH Combiners are designed and engineered with state-of-the-art techniques, and realized with cutting-edge manufacturing technology, in order to grant the maximum reliability and deliver the most advanced performances: highest voltage safety margins, lowest insertion loss, maximum compactness, exceptional mechanical stability, durability, and immunity to transportation shocks.

  • Full-Band Tunability
  • Temperature Stabilization
  • DC-Short
  • Modular Connector System
  • Modular Frame System
  • 10-Year Warranty


COM-TECH Combiners can be provided with specific Options to efficiently reduce their over-temperature, and to consequently increase their maximum operating power. The resulting downsizing possibility allows significant cost and space savings. These options are add-ons, which means that they can be applied at a later stage:

  • Heat Sinks
  • Forced Air Cooling
  • Liquid Cooling

COM-TECH Combiners have been engineered to be conveniently fit into Racks. COM-TECH can provide standard and customized solutions to integrate Filters, Combiners, Directional Couplers, Lowpass Filters, and other components into Racks.
