The Model 10943B redundancy switch is considered the "gold-standard" for automated back-up switching for both digital and analog signals up to 2400MHz.

Critical applications such as in satellite broadcast or military require redundant (backup) systems. Our redundancy switchers provide an automated method of providing this function. Under program control, manual, or direct alarm input, this unit provides either 1:1 backup or 1:4 (one backup unit for every four).


  • Ultra-High reliability relay technology
  • No distortion or gain issues
  • Four channels of A/B 2400MHz (L-Band) redundancy
  • Signals pass without power
  • SMA or F-Type signal connectors
  • Standard 50 ohm (others optional)
  • Routes both digital and analog signals to 2400MHz
  • Dual mode 1:4 or 1:1 backup switching
  • Dual serial control ports, or one serial & one Ethernet
  • Field configurable serial ports (232C/422A/485)
  • Dry contact direct alarm input port (with indicators)
  • Programmable driver output port for external devices
  • Rear panel indicator status LEDs
  • Front panel LED back-lit keypad controls
  • High contrast vacuum-fluorescent display
  • Rugged 1RU high chassis (1.75”)
  • International AC power range (DC optional)
  • Self-monitoring hot-swap plug-in power supplies
  • Integrated rack mount design (19 inch)
  • Certified CE EN61010 (LVD)
  • Applications

    Our 10943B is provides automated redundancy switching of equipment with single-ended digital or analog signals to 2400MHz.

    Rather than using patch cords, distribution amplifiers and multi-couplers, the following installations may benefit from use of this product:

  • Broadcast centers
  • ENG vans and trucks
  • L-Band telemetry receivers
  • Tracking and test bases
  • Satcom ground stations
  • Telecom installations

    Detailed Description

    The 10943B Redundancy (backup) L-band Switching System provides backup selections for signals as high as 2400MHz. This product delivers ultra-high signal performance coupled with very advanced remote/manual control and monitoring. Dual serial ports, or Ethernet and a single serial port configurations are available.

    Designed specifically for ENG trucks, and for the general satellite/communications industry, the 1RU high rack mount unit provides the user with normal through paths for four channels of signals (four in and four out). Under front panel, remote serial control, Ethernet or direct alarm input control, the unit can select a backup signal to replace a suspect input signal. This unit is considered the "gold standard" for L-Band redundancy switching with nearly 800 units deployed in the field.

    Redundancy costs can be significantly reduced by utilizing the unit's 1:4 mode where a single backup unit can be switched in for any of the four channels. This redundancy method basically cuts your redundancy costs by 75%. User programmable "priority" setting specifies the order of backup priority for the single backup.

    Besides the hot-swap power supplies at the front panel, it also includes a VF display, manual keys for local control and a host of status LEDs. The manual controls may be locked to prevent unintentional operation. Self-monitoring hot-swap plug-in power supplies are standard with an independent and redundant design. The unit has an international AC power input designed for any international AC power source, and an optional wide-range DC power input is available.
