The Johansson 6023 is a compact inline LTE/4G filter designed to eliminate interference from 4G mobile networks in TV antenna distribution systems. It passes the full terrestrial TV band (5–782 MHz) while rejecting LTE signals on UHF channels 61–69 (800 MHz band) with up to 25 dB attenuation, restoring clear picture quality on channels affected by nearby mobile masts.

The 6023 is designed for straightforward indoor installation — it connects directly in-line on the coaxial distribution network between the antenna outlet and the TV or set-top box, with no power supply required thanks to its DC pass-through capability.

Key Features

• LTE/4G inline filter for indoor TV antenna installations
