For Samsung Galaxy A21s , A217 - Replacement Coaxial Antenna Flex

Restore 4G LTE, Wi-Fi, and Bluetooth signal integrity with this High-Frequency RF Coaxial Interconnect. Specifically engineered for the Samsung A21s (SM-A217), this cable bridges the RF signal path between the main logic board and the charging port sub-board. Featuring micro-miniature coaxial (MHF4) connectors with high-retention force, it ensures a low-loss 50 ohm impedance match for optimal radio frequency transmission. This component is critical for resolving hardware-level failures such as "No Service" errors, fluctuating signal bars, or poor data throughput caused by a kinked, pinched, or oxidized cable.
