Eliminate 5G and LTE TV Interference
This bandpass filter instantly stops digital TV picture freezing and audio drops caused by nearby 5G and 4G LTE mobile towers. As mobile networks expand into the 700MHz spectrum, their strong transmission signals often overwhelm standard TV antennas, causing severe pixelation and signal loss. The EIGHT LBF-700E acts as a strict gatekeeper, allowing essential Digital Terrestrial Television (DTV) signals (5-694MHz) to pass through flawlessly while aggressively rejecting interfering frequencies from 694MHz to 862MHz.
Universal F-Type Coaxial Connection
The EIGHT LBF-700E connects effortlessly to any standard 75Ω TV antenna setup using universal F-type screw connectors. Its compact, inline design (measuring just 68x26x16mm) means it can be easily installed behind your wall-mounted TV or directly inside an antenna distribution box without requiring any external power. Furthermore, the robust metal casing provides excellent shielding against external electromagnetic interference, ensuring a pure and uninterrupted signal path.
Pro Tip from Our Technicians
Always install the 5G filter as close to the receiving antenna as possible, and strictly before any signal amplifiers. Our Sham Shui Po AV specialists note that if an amplifier boosts the raw signal before filtering, the 5G interference will also be amplified, potentially overloading the filter and your TV tuner. Placing the EIGHT LBF-700E before the amplifier guarantees that only the clean TV signal is boosted and distributed.

FAQ Section
FAQ Section
- Will this filter reduce my normal TV signal strength?No, the EIGHT LBF-700E is designed to pass 5-694MHz TV signals with minimal insertion loss while only blocking the higher 5G/LTE frequencies.
- Is this filter better than buying a new "5G-ready" TV antenna?Yes, adding this filter to your existing antenna is a much more cost-effective solution than replacing your entire antenna setup, providing the exact same interference rejection.
- Where exactly should I install this filter in my TV setup?You should install the filter inline on the coaxial cable coming from your antenna, ideally placing it before any signal splitters or amplifiers for the best results.
- Does this filter work with Hong Kong's specific digital TV broadcasting frequencies?Yes, this filter perfectly matches Hong Kong's DTV spectrum, allowing local channels to pass while blocking the specific 700MHz 5G bands used by HK telecom operators.
- Can I use this filter outdoors on my rooftop antenna mast?No, the EIGHT LBF-700E is an indoor filter and lacks waterproofing, so it must be installed inside your home or within a weatherproof enclosure.
