Axing LTE/5G Filter TZU 198-65, frequency range 5–694 MHz, model TZU 198-65

Axing LTE/5G filter TZU 198-65 is a passive inline filter designed for signal conditioning in television and antenna systems operating across the 5–694 MHz frequency range. The device attenuates out-of-band signals from LTE and 5G mobile networks while allowing broadcast and cable transmissions within the specified band to pass with minimal impact. It is intended for use in domestic and commercial antenna installations where suppression of mobile-network interference is necessary to maintain picture and sound quality.

Advantages

The filter provides targeted suppression of LTE and 5G interference without active power requirements, offering a low-maintenance solution for improving reception stability. Its inline form factor allows straightforward integration into existing antenna and distribution lines. Designed for broadband operation across 5–694 MHz, the unit preserves the desired broadcast spectrum while reducing unwanted mobile signal noise.

Suitable for

• Residential rooftop and indoor antenna systems
• Apartment building and multi-dwelling distribution networks
• Small commercial TV distribution and reception points
• Situations with nearby mobile transmitters causing interference

Key specifications

• Operational frequency range: 5–694 MHz
• Passive inline filter topology for antenna/coax lines
• Designed to attenuate out-of-band mobile signals (LTE/5G) while passing broadcast/cable frequencies
• Connector type: inline coaxial connection suitable for standard RF cabling
• Slim housing suitable for mounting in distribution boxes or inline on coax runs

How to use

Install the filter inline on the coaxial feed between the antenna and the receiver or distribution amplifier, observing correct connector orientation and ensuring secure coax connections. Place the unit at a point where interference is entering the system, such as at the antenna feed or immediately before a multiswitch or amplifier input. No external power is required. After installation, verify signal levels and channel quality on connected receivers and adjust placement if necessary to achieve optimal suppression without degrading desired channels.

Usage recommendations

Use the filter as close as possible to the antenna feed or at the entry point of the building distribution to maximize suppression of mobile-network interference. When combined with low-loss coax and properly grounded installations, the filter contributes to stable reception. Avoid placing the filter after active amplifiers unless recommended by a signal technician, as placement can affect overall system gain and noise figure.
