High-pass electronic filter Axing TZU 19-66 Stopband 5-68 MHz Passband 85-2400 MHz

The Axing TZU 19-66 high-pass electronic filter blocks low-frequency signals in the stopband from 5 to 68 MHz while allowing signals in the passband from 85 to 2400 MHz to pass with minimal attenuation. Designed for use in RF signal distribution, the unit features F-type male connectors and compact construction suitable for inline installation on coaxial cables. The filter functions as a return path blocker and helps prevent interference from VHF and other low-frequency sources without affecting broadband and satellite signals in the higher frequency range.

Advantages

The filter provides a clearly defined frequency separation that preserves signal integrity in the passband and suppresses unwanted low-frequency interference. Its F-type male connectors enable straightforward inline connection to existing coaxial installations. The compact design facilitates mounting in distribution boxes, wall plates or near equipment, while the wide passband supports a broad range of television, satellite and broadband signals up to 2400 MHz.

Suitable for

• Blocking return-path signals and VHF interference in home and commercial coaxial networks
• Protecting distribution systems feeding receivers, set-top boxes and broadband modems
• Integrating into antenna distribution panels and multiswitch installations
• Inline use on coax runs to separate downstream and upstream frequencies

Key specifications

• Stopband frequency range: 5–68 MHz
• Passband frequency range: 85–2400 MHz
• Connector type: F-type male (both ends)
• Function: High-pass filter / return path blocker
• Application: Coaxial RF signal distribution and interference suppression

How to use

Install the Axing TZU 19-66 inline on a coaxial cable by connecting the F-type male connectors to compatible F female ports or using short adapters as required. Place the filter at the point where low-frequency interference or unwanted return-path signals must be blocked, such as at the splitter input, distribution panel, or before a receiver bank. Ensure connectors are tightened to prevent signal loss and avoid kinking the cable. No power supply or configuration is required; the device works passively once installed.

Usage recommendations

For optimal performance, position the filter close to the source of interference or at network segmentation points. Confirm that connected equipment operates within the specified passband (85–2400 MHz). Use quality coaxial cable and proper shielding practices to maintain isolation and minimize additional signal loss.
