Avionic Crossband Repeater

X-Band 50

Bridging the Gap Between Bands
Connecting VHF to UHF, UHF to UHF, and VHF to VHF, the X-Band 50 provides full UHF and VHF interoperability. This crossband provides an interoperable solution that provides over-the-air programming (OTAP). The X-Band 50 is compact in size, easy to use, and operates as a control station without the need of a network. Inter-agency communications just got easier!

Main Features:

  • Local controlled operation; set on a desktop and use as a dual base unit with an optional microphone
  • Alpha tag your channels with the 8-Character alphanumeric display
  • Easily mounts into a 19" rack frame

Configurable to 120V or 220V AC input

No need to worry if there is a power failure. The X-Band Air can switch over to customer-supplied 12 volt DC battery backup if AC power fails.

Advanced Multi 2-Tone/5-Tone Systems

Programmable actions when a matched tone is received

  • Bell icon indication ON/OFF/blink
  • Answer back calls
  • Beep sounds
  • Scan start/stop
  • Auto transmission
  • Stun/kill functions (prevents use of a lost or stolen radio)
  • 32 Tx and 9 Rx 5-Tone codes available
  • 11 Tx and Rx 2-Tone codes available

Other Features

  • 10 scanning lists and normal/priority scan
  • Power ON password
  • Backlit LCD and keys for night time operations
  • Meets MIL-STD 810 C, D, E and F specifications

Radios, controller, and power supply, all in one box. Dual forced-air fans keep the unit cool. 19" Rack mountable. Battery backup capable.

A clean rear panel design allows for easy setup and operation. An options connector allows for customized applications such as Interconnect, CWID, and more.
