RF Patch Panels

Flexible Signal Routing & Switching for Broadcast

In a dynamic broadcast environment, the ability to reroute RF signals quickly and safely is essential. Whether you need to switch a transmitter to a backup antenna, divert power to a dummy load for testing, or bypass a combiner module, COM-TECH Patch Panels provide the ultimate manual switching solution.

MDL Communications offers COM-TECH’s complete line of modular patch panels. Designed for high-power applications (FM, VHF, UHF), these units replace complex motorized switch assemblies with a cost-effective, fail-safe manual routing system perfect for both transmission sites and R&D test labs.

 

Key Features & Benefits

1. Safety First: Integrated Interlocks

Manual switching of high-power RF lines carries risk if the transmitter is active. COM-TECH patch panels feature Floating Independent Interlock Contacts.
How it works: When a U-link is removed, the interlock circuit immediately opens, signaling the transmitter to mute or shut down before the RF path is broken. This protects both the operator and the equipment from hot-switching arcs.

2. Modular "U-Link" System

The core of the system is the precision-engineered U-Link (U-Bend). These rigid coaxial links are designed for rapid removal and re-insertion, allowing you to change signal paths in seconds.

  • Low Insertion Loss: Silver-plated inner conductors minimize loss.
  • Consistent VSWR: Precision machining ensures a perfect 50-ohm match every time.

 

3. The Modular Connector System

COM-TECH’s proprietary design allows for incredible flexibility. The front panel ports can be adapted to various rigid line sizes using standard adapters, meaning one patch panel frame can evolve with your station's needs.

Configurations & Applications

For Broadcast Stations

Standard 3-Port or 4-Port configurations are ideal for "N+1" redundancy systems or simple Antenna/Load switching.
Common Setup:

  • Port 1: Transmitter Input
  • Port 2: Antenna Output
  • Port 3: Dummy Load

 

For Test Labs

Larger 6-10 port matrices allow engineers to rapidly route signals between multiple amplifiers, exciters, and measurement equipment without constantly unscrewing rigid line flanges.
