LMR195 Cable RP SMA Female To SMA Male RF Coaxial Cable

Maximize the reach and reliability of your wireless applications with this professional-grade LMR-195 Coaxial Cable Assembly. Engineered to bridge the common connectivity gap between standard and reverse-polarity Small Form Factor (SMA) devices, this cable features an RP-SMA Female connector on one end and a standard SMA Male connector on the other. It's the essential component for seamlessly integrating commercial-grade SMA equipment with consumer RP-SMA devices, or for converting connection types in complex radio setups.

Using genuine LMR-195 low-loss cable, this assembly delivers significantly better performance than comparable thinner cables like RG-58 or RG-174, making it ideal for applications where maintaining signal integrity over short to moderate distances is critical. Whether you're upgrading a Wi-Fi network, setting up a LoRa gateway, or optimizing a GPS/GNSS installation, this is the reliable, high-bandwidth connection you need.

Unmatched Signal Integrity with LMR-195 Coax

The core of this high-performance cable assembly is the LMR-195 coaxial cable, renowned for its low signal attenuation and superior shielding effectiveness.

Low-Loss Performance for High Frequencies

LMR-195 cable is designed with a foam polyethylene dielectric and a double-shielded construction (foil shield plus tinned copper braid), which dramatically reduces signal loss compared to traditional braided-only cables.

• Superior Attenuation: At key Wi-Fi frequencies (2.4 GHz), the LMR-195 cable's attenuation is substantially lower than that of RG-58 (a common drop-in replacement), ensuring more power is delivered to your antenna and improving both transmission and reception range.

• High-Bandwidth Capacity: This cable maintains excellent performance up to 6 GHz, fully supporting all current Wi-Fi standards (802.11 b/g/n/ac/ax) as well as LTE/4G and UHF frequency bands.

• Robust Double Shielding: The $>90\text{ dB}$ shielding effectiveness provides excellent immunity to Electromagnetic Interference (EMI), which is crucial in noisy industrial or urban environments.

Mechanical Flexibility and Durability

With an approximate diameter of 0.195 inches ($\approx 5\text{ mm}$), the LMR-195 strikes the perfect balance between low-loss performance and manageable flexibility.

• Ease of Installation: Its solid center conductor provides a tighter bend radius than other stiff, lower-loss cables, allowing for easier routing and installation in compact spaces or inside enclosures.

• Outdoor Ready: The rugged polyethylene (PE) jacket is UV-resistant and built for a wide operating temperature range (typically −40∘C to +85∘C), making this assembly an excellent choice for outdoor antenna setups.

The Connectivity Bridge: RP-SMA Female to SMA Male

This specialized assembly provides a unique solution for connecting components with different SMA gender and polarity configurations.

RP-SMA Female Connector

The Reverse Polarity SMA (RP-SMA) Female connector is most commonly found as the antenna port on consumer-grade Wi-Fi routers, access points, and some radio modules.

• Bulkhead Compatibility: The female connector is typically a bulkhead mount style, allowing it to be securely mounted to a panel or enclosure wall. This provides a clean, protected transition for the signal from the cable to an external RP-SMA male antenna.

• Connection Point: It accepts standard RP-SMA male antennas or extension cables.

Standard SMA Male Connector

The SMA Male connector is the universal standard in industrial, cellular, GPS, and professional radio equipment.

• Device Connection: It plugs directly into the SMA Female jack found on GPS receivers, LTE modems, RFID readers, test equipment, and many industrial IoT devices.

• Connection Point: The SMA Male connector features external threads and a center pin.

Conversion and Adaptation

This cable is a vital RF adapter cable that resolves compatibility issues, allowing you to:

• Connect a standard SMA device (e.g., a commercial GPS tracker) to a custom-mounted RP-SMA antenna port.

• Use an RP-SMA female bulkhead port on an enclosure to feed an internal SMA radio module.

• Bridge older RP-SMA gear with newer SMA standard components without relying on lossy brass adapters.

Key Usage Scenarios

The low-loss properties of LMR-195 paired with the connector conversion make this assembly essential for:

1. Wi-Fi and WLAN Enhancements

• Router & Access Point Upgrades: Connecting a high-gain, commercial SMA-male antenna to a Reverse Polarity SMA-female router port for improved range and signal quality.

• Long-Range Wireless Bridges: Used in short-to-medium distance runs where minimizing loss is paramount for point-to-point wireless links operating in the 2.4 GHz and 5 GHz bands.

2. GPS/GNSS and LoRa Systems

• High-Precision GPS: Connecting external GPS antennas to industrial or surveying equipment that utilize SMA connectors, ensuring minimal signal degradation for accurate positioning data.

• IoT and M2M Gateways: Providing a reliable, low-loss link for LoRaWAN or SigFox gateways and radio modems that require a durable, outdoor-rated cable to link to an external antenna.

3. Test & Measurement

• Lab and Field Testing: Employed as a high-quality jumper for connecting spectrum analyzers, signal generators, and other RF test equipment (often SMA equipped) to systems under test that use the RP-SMA interface.
