The Model 109920 1-Channel 110V Gate Receiver is designed for use in gate operator applications. An 11-inch wire whip antenna is included for local reception. The whip antenna connects to the receiver's Type-F antenna connector. If the receiver is mounted inside a shielded metal enclosure such as a gate operator housing an external Model 106603 Remote Whip Antenna should be used.,The receiver includes a 24-volt AC power transformer that plugs directly into a 115 VAC power outlet. The normally open relay output can switch up to 1 amp @ 30 VAC. A 3-foot 2-conductor wire lead with spade lugs is provided for attachment to the gate operator's radio activation terminals.,The receiver is programmed with a 10-position coding switch. When a Multi-Code transmitter set to the same code is activated the receiver's output will activate triggering the gate operator.
