Long Distance Dual-Channel Gate Receiver with Remote Antenna Support The Linear GRD-2 is a long distance, dual-channel coax gate receiver designed for automatic gate operators where extended antenna placement or improved reception is required. Using Linear’s Delta-3 fixed-code radio format, the GRD-2 delivers reliable access control for single or dual gate applications and supports independent channel operation for gate open, close, or auxiliary functions. This receiver features auto voltage sensing, eliminating the need for jumpers, and can be powered directly from most gate operators. Dip switch programming provides straightforward setup with consistent, fixed-code performance suitable for controlled-access environments. Key Features Dual-channel gate receiver for independent gate control functions Delta-3 fixed-code radio format with dip switch programming Supports remote antenna placement using coax connection Auto voltage sensing with no jumpers required Two normally open relay outputs for gate control circuits Technical Specifications RF Frequency: 310 MHz Radio Format: Linear Delta-3 Number of Channels: 2 Code Capacity: 256 possible codes (dip switch set) Relay Type: Two Form A (normally open) relays Relay Rating: 30 VAC or VDC up to 5 A Power Input (AC): 12–30 VAC Power Input (DC): 10.5–30 VDC Antenna Connection: 75-ohm F connector Included Antenna: Whip antenna Included Coax Length: 3 feet Dimensions: 3.625 in W × 5.25 in H × 1.5 in D Compatibility Notes Compatible with Linear Delta-3 transmitters Designed for use with automatic gate operators only Replacement for the discontinued Linear DR-2 gate receiver Conclusion The Linear GRD-2 long distance gate receiver provides dependable dual-channel control with extended antenna flexibility and fixed-code Delta-3 reliability. Its wide voltage range, robust relay outputs, and simple dip switch configuration make it a proven solution for residential and commercial gate systems. Download Specs Download Manual
