Linear Nf-469 Notch Filter

Optimize channel allocation and eliminate interference in security and monitoring networks with the Linear NF-469 Notch Filter. This inline notch filter removes incoming CATV channels 64–70 and off-air UHF TV channels 14–19, giving modulators clear, interference-free spectrum to insert custom channels for CCTV, access control, and remote monitoring. Rated across a 469.25–497.25 MHz band, the NF-469 prevents modulated signals from broadcasting back into the coax, protecting upstream distribution and preserving signal integrity for live surveillance and security systems. The compact 3.25" design installs easily at the source or before splitters and bi-directional DA-series amplifiers, making it a practical choice for both retrofit and new-build deployments. Engineered by Linear and compatible with 5400, 5500 and SVM series modulators, it delivers reliable performance in commercial monitoring, multi-dwelling, and enterprise CATV environments. Add the NF-469 to your coax infrastructure to free channels for modulators and ensure cleaner, more stable feeds for security and surveillance applications — order or specify it for your next installation.
