The Johansson 6030 is a compact inline LTE/4G filter for indoor TV antenna installations, designed to eliminate interference from 4G mobile networks on the 800 MHz band (UHF channels 61–69). It passes the full terrestrial TV signal band (5–782 MHz) with just 1 dB insertion loss while rejecting LTE signals by 20 dB, delivering noticeably improved picture quality on affected channels.

The 6030 connects directly in-line on the coaxial distribution network via its IEC connectors, making it ideal for plug-in installation directly behind a TV set or set-top box. Its DC pass-through allows continued use of powered antennas and masthead amplifiers.
