SMA RG58 Antenna Extension Cable — 50Ω Male to Female, 65.6 ft

Construction and shielding - The cable uses a copper braid combined with an aluminum mylar foil for double-layer shielding around an RG58 dielectric. That combination reduces external interference and preserves signal strength better than single-layer shielded RG58 or the thinner RG316/RG174 options.

Electrical and mechanical details - Built to 50 ohm impedance, this SMA male‑to‑female coax is designed for low loss over longer runs and higher frequency signals. The cable remains flexible enough for routing in tight spaces or around corners while still providing a heavier, more robust build than lighter-gauge jumpers.

Typical uses - Use this extension for Wi‑Fi antennas, RTL‑SDR USB dongles and ADS‑B receivers, ham and amateur radio setups, GPS navigation antenna extensions, and PCIe or mini‑PCIe wireless cards where a longer lead is required.

Compatibility - Works with 4G/ LTE mobile routers and gateways, vehicle and mobile cellular installations (cars, RVs, trucks), trail and security cameras that accept SMA connectors, industrial 4G routers, and IoT/M2M terminals that require a 50Ω feed.

Package contents - Includes one SMA male to SMA female RG58 low-loss antenna extension cable with an overall length of 65.6 ft. Connectors are standard SMA types for easy mating with compatible antennas and radio/network equipment.
