Ultra-Low Loss N-Type Male to N-Type Male LMR400 Coaxial Cable Assembly

Minimizing signal attenuation across long physical runs requires industrial-grade, highly shielded transmission lines designed for demanding microwave frequencies. The premium N-Type Male to N-Type Male LMR400 coaxial cable assembly from OHM Cables provides a high-performance RF link engineered to hook up high-gain antennas, wireless routers, cellular signal boosters, and sensitive laboratory testing equipment. Calibrated to maintain a precise $50 \Omega$ system impedance, this professional-grade cable utilizes dual-shielding technology and a solid core conductor to ensure your signal travels with the absolute minimum insertion loss, preserving maximum transmitter power and receiver sensitivity.

Standard low-spec RG58 or RG8X jumpers introduce massive attenuation at microwave frequencies like 2.4 GHz or 5.8 GHz, turning valuable transmit power into wasted heat. Our premium N-Type Male to N-Type Male LMR400 equivalent RF cable solves this bottleneck by employing a much larger, high-efficiency physical geometry. Built with a solid copper-clad aluminum center conductor, gas-injected foam polyethylene dielectric, and a dual-layer outer shield consisting of $100\%$ coverage aluminum tape plus a tight tinned copper braid, this assembly restricts signal leakage while blocking external electromagnetic interference (EMI) in high-density RF environments.

Why LMR400 (or High-Performance Equivalent) is the Industry Standard

For outdoor wireless deployments, selecting the right cable type makes the difference between an optimal gigabit-link and constant connection drops. The OHM Cables N-Type Male to N-Type Male LMR400 coaxial lead provides massive structural advantages over traditional braided lines:

1. Exceptional Low Attenuation Profiles

LMR400 equivalent cable features an outer diameter of approximately 10.3 mm (0.405 inches), allowing for a larger dielectric core. This physical thickness dramatically lowers resistive losses over distance. For example, at 2400 MHz, standard LMR400 loses only about 21.5 dB per 100 meters, compared to over 70 dB of loss on thin RG58 cables.

2. Double Shielding for $100\%$ RF Isolation

To operate reliably near cellular towers, high-voltage lines, or heavy-duty machinery, this N-Type Male to N-Type Male LMR400 cable utilizes a multi-layer shielding architecture. The inner aluminum tape layer is bonded directly to the gas-injected foam dielectric to provide $100\%$ high-frequency coverage, while a secondary tinned copper wire braid delivers extra mechanical strength and excellent low-frequency grounding. This combination achieves a shielding effectiveness rating of greater than 90 dB.

3. Rugged Weatherproof Terminations

An outdoor cable run must withstand extreme UV exposure, wind loads, and heavy rain. Our premium assembly features heavy-duty N-Type Male connectors machined from solid brass, heavily finished in non-tarnish nickel, and equipped with gold-plated center pins. Underneath the dual-wall adhesive-lined heat shrink tubing, internal silicone O-ring gaskets are compressed to prevent moisture ingress from wicking down the braided shield.

Advanced Materials & Long-Term Performance Consistency

Every element of the N-Type Male to N-Type Male LMR400 assembly is selected to guarantee electrical stability over decades of operation. The outer jacket is constructed from a heavy-duty, UV-resistant Polyethylene (PE) compound. This hard, durable jacket material is built to endure direct sunlight, freezing rain, and physical abrasions without cracking or degrading, making it perfect for roof-to-rack outdoor cable runs.

The interior dielectric consists of gas-injected closed-cell foam polyethylene (FPE). Compared to solid plastic dielectrics, this micro-cellular structure has a high velocity of propagation ($85\%$), meaning signals travel faster and experience less capacitive attenuation, keeping your data waves clean and crisp.

Typical Applications and Installation Scenarios

• Outdoor Cellular Boosters & Repeaters: Linking external high-gain Yagi or omnidirectional antennas to indoor bi-directional amplifiers (BDAs).
• Wireless ISP & Outdoor Wi-Fi Mesh Systems: Connecting sector or panel antennas directly to high-power outdoor radios or access points.
• Ham Radio & VHF/UHF Base Stations: Creating low-loss jumpers to connect transceivers to inline surge protectors and antenna tuners.
• GPS and Satellite Telemetry: Routing low-noise, high-frequency signals from roof-mounted receivers to internal processing hubs.

Why Choose OHM Cables Assemblies

At OHM Cables, we believe that an entire wireless installation is only as good as its weakest terminal connection. That is why we do not use cheap copper-clad steel (CCS) braid, zinc connector housings, or thin flash platings that oxidize under outdoor exposure. Every N-Type Male to N-Type Male LMR400 assembly is precision-soldered, hex-crimped on industrial tooling, and protected with dual-wall adhesive heat shrink tubing. Our rigorous quality control ensures that each finished jumper is swept on vector network analyzers (VNAs) to verify perfect VSWR and insertion loss before leaving our workshop.

Frequently Asked Technical Questions (FAQ)

What is the minimum bend radius of this LMR400 equivalent cable?

For installation curves, the minimum bend radius of this LMR400 equivalent cable is approximately 25.4 mm (1.0 inch) for a single bend, and 101.6 mm (4.0 inches) for repeated flexing. Forcing the cable into sharper bends can crimp the aluminum shielding tape, distort the foam dielectric, and alter the $50 \Omega$ line profile, causing immediate return loss spikes.

Is this cable assembly suitable for direct burial?

Our premium assembly is equipped with a dense, highly water-resistant Polyethylene (PE) jacket designed for heavy outdoor weathering. While it handles direct burial quite well in standard soils, we highly recommend running cables through a simple PVC or flexible conduit if they will be buried in areas with high water tables or sharp rocks to prevent accidental physical punctures.

Can I use this LMR400 cable for standard satellite TV applications?

No. Satellite and cable television systems run on a $75 \Omega$ system standard (typically using RG6 or RG11 cables with F-Type connectors). This premium N-Type Male to N-Type Male LMR400 assembly is designed for a true $50 \Omega$ standard, which is the universal match for commercial wireless transmitters, cellular equipment, and microwave communication arrays.
