Coaxial Cable for LG V40 ThinQ

The Coaxial Cable in your LG V40 Thinq is a shielded RF transmission cable that carries radio frequency signals between the antenna elements and the motherboard's RF processing chips. Its coaxial construction — a central conductor surrounded by shielding — prevents signal loss and interference during transmission. A damaged coaxial cable causes measurable signal degradation across mobile network, WiFi, Bluetooth, and GPS functions on your LG V40 Thinq.

A standard antenna flex cable carries signals along a flat ribbon conductor, while the Coaxial Cable uses a round shielded construction with a central conductor and grounded outer shield. The Coaxial Cable provides superior signal integrity and interference rejection — it is used specifically for high-frequency RF signal paths on LG V40 Thinq where signal quality is critical.

Signs include gradual or sudden degradation of signal quality across multiple wireless functions — weaker mobile signal, reduced WiFi range, less accurate GPS, and Bluetooth dropping at shorter distances than usual on your LG V40 Thinq. Physical inspection may reveal kinking, crushing, or damage to the cable's outer shielding from a previous repair or drop.

Coaxial Cable replacement requires careful routing inside the phone chassis and correct seating of the IPEX or U.FL connectors at each end. It does not require soldering in most cases but does require the phone to be opened and components carefully moved to access the cable path on your LG V40 Thinq. Professional handling is recommended.

Yes — a 7-day replacement warranty covering manufacturing defects is included. An unboxing video is mandatory for all warranty claims. Cables showing physical damage from improper installation are not covered under warranty. For more information, check out SAHII's Return Policy.
