Product-specific buyer note

Do not treat this as currently manufactured stock. RTL-SDR Blog says V4 production ended in May 2026 and warns that marketplace listings may be counterfeits containing V3-clone circuitry. Fab.to.Lab marks its exact page discontinued. If residual stock appears, verify the RTLSDRBlog and Blog V4 EEPROM identity, sealed origin and return rights; otherwise compare the continuously produced V3 or forthcoming V4L. V4 requires current V4-compatible drivers and does not transmit.

India regulatory note

Use only for lawful reception and do not intercept, decode or redistribute communications prohibited by Indian law. The bias tee can damage hardware if applied into a DC-short antenna path; understand the load and disable it when not required.
