Adaptor reverse polarity SMA male to SMA male Nedis AD/SRP-M:SMA-M

Nedis AD/SRP-M:SMA-M is a reverse-polarity SMA male to SMA male coaxial adapter designed to join devices that use reverse-polarity SMA male interfaces with standard SMA male connectors. The compact metal body and SMA precision connectors enable reliable signal transfer between antennas, RF equipment, routers and test instruments where a direct SMA male-to-male mating is required.

Advantages

The adapter provides a straightforward mechanical solution for connecting incompatible SMA male terminations without modifying cables or equipment. Its reverse-polarity configuration preserves correct signal polarity while maintaining a secure threaded coupling. The small form factor reduces stress on existing cabling and makes integration into tight installations easy. Constructed for consistent RF contact, it supports repeatable connections for measurement and networking tasks.

Suitable for

• Connecting an antenna with reverse-polarity SMA male to router or modem with standard SMA male
• Joining RF test equipment and measurement fixtures requiring SMA male-to-male coupling
• Adapting external antennas to wireless devices in constrained spaces
• Temporary field setups and troubleshooting where connector compatibility is needed

Key specifications

• Connector type: reverse-polarity SMA male to SMA male
• Impedance: 50 ohm
• Construction: coaxial threaded SMA interface
• Material: metal housing with plated contacts
• Frequency range: suitable for typical RF and Wi‑Fi frequencies (application-dependent)
• Size: compact inline adapter for minimal cable strain

How to use

Align the reverse-polarity SMA male end of the adapter with the reverse-polarity SMA male connector on the device or cable and gently screw the adapter until snug. Then align and screw the standard SMA male end to the mating SMA female or male connector as required by the installation. Tighten by hand to ensure a secure connection; avoid excessive torque to prevent damage to the SMA threads. Verify continuity or signal through the chain with appropriate RF testing equipment if precise measurements are needed.

Usage recommendations

Use the adapter in dry, clean environments and avoid exposure to corrosive substances. For best RF performance, keep cable runs short, ensure connectors are clean and free from debris, and do not overtighten the SMA threads. When used for measurements, confirm the adapter’s impact on insertion loss within the frequency band of interest.
