Push back gateways provide a seamless connection to aircraft interphone via an adapter cord included with each gateway. The gateways offer hands-free, full-duplex intercom for up to 4 headsets with belt stations per gateway (range: 300′ line-of-sight).

ateways act as a relay for all audio between belt stations and existing wired intercom. Multiple gateways can work independently within the same RF vicinity with no cross-talk. Gateways come with an orange, rubberized protective skin for high visibility on the tarmac, as well as a “Remove Before Flight” banner, hook / lanyard.

Gateway features include:

• Link / PTT button for close-proximity link process to belt stations
• System Gain for mater volume control of wireless system components
• LED indicator for visual status of comm link and battery charge
• Marine-grade, water-tight enclosures (IP-67 minimum) for harsh environments
• EU version is available
