The Linear 106604 9 Inch Whip Antenna is a factory replacement RF antenna designed for Linear/Nortek Control radio receivers used in garage door openers, gate operators, and access control systems. As a quarter-wave whip, it helps restore and optimize reception for compatible Linear receivers operating in the mid‑UHF band commonly used by the brand. It’s a straightforward drop-in replacement for damaged or missing antennas and is suitable for both residential and commercial applications where reliable remote range and signal stability are required.
Engineered for Linear radio controls in the 300–320 MHz range (including systems labeled 310 MHz Delta‑3 and 318 MHz MegaCode), the 106604 works when matched to the frequency of the receiver it’s paired with. No programming is required: install it on the designated antenna mount or terminal of the Linear receiver and orient it vertically for best performance. For optimal range, keep it clear of large metal objects and enclosures, and follow the receiver’s installation notes. Always power down equipment before servicing antennas and ensure all connections are secure. Common use cases include replacement or upgrade on Linear RF receivers for garage doors, gates, telephone entry units, and standalone access control modules that specify a 9-inch whip antenna under Linear part number 106604.
