Tired of signal dropouts, high insertion loss, and bulky setups that compromise your RF network?

Enter our LL400 Coax Cable with 4.3-10 Male Connectors—the game changing, low loss powerhouse engineered for mission critical wireless connectivity.

This premium 50-ohm coaxial cable is a direct equivalent to industry gold standards like LMR-400 and delivers ultra-low attenuation and unmatched flexibility, all terminated with rugged 4.3-10 male connectors for seamless integration into modern telecom infrastructures.

Why This Cable is Your Network’s New Best Friend:

• Ultra-Low Signal Loss for Crystal-Clear Transmission: With foam dielectric construction and a 10mm diameter, the LL400 minimizes attenuation to just ~0.95 dB at 50 MHz over 125 feet—keeping your data flowing fast and far, whether it’s GPS signals, mobile antennas, or high-frequency RF feeds. Perfect for antenna feeder runs in LMR, PMR, and broadband wireless apps where every dB counts.

• Rugged 4.3-10 Male Connectors: Compact Powerhouse Reliability: These IP67-rated beasts offer low PIM performance (independent of torque) and excellent VSWR up to 6 GHz, making them the ideal upgrade from bulky 7/16 DIN types—40% lighter, smaller, and optimized for dense cell tower installs. Radially loaded O-rings ensure waterproof, dust-proof seals for outdoor endurance, while silver-plated contacts boost conductivity and corrosion resistance.

• Flexible Yet Bulletproof Build: Lightweight polyethylene jacket (UV-resistant for 20+ years of service) handles bends, vibrations, and harsh environments—from rotating beam antennas to shipboard military systems—without cracking or degrading. Double-shielded for interference rejection, it’s a drop-in replacement for RG-8 or Belden 9913 in ham radio, CB ops, or WLL setups.

• Versatile Applications That Scale: Tailored for cellular base stations, RRU-to-antenna jumps, broadcasting, and data transmission—anywhere high-frequency (DC to 6 GHz) demands low-loss precision. Custom lengths available for jumpers, pigtails, or long hauls.

• Easy Install, Zero Hassle: Pre-terminated for quick snap-in connections—no special tools needed beyond a torque wrench. RoHS compliant and globally trusted (even by HAARP pros), it’s built to last without the premium price tag.

Available in standard lengths or custom assemblies, this isn’t just a cable—it’s your ticket to interference free, high speed RF dominance.

Tired of signal loss robbing your RF setup of its full potential? Say goodbye to frustrating drop-offs and hello to crystal-clear, reliable connections with our premium LL400 Low Loss Coaxial Cable, precision-terminated with a rugged 4.3-10 Male connector on one end and a versatile SMA Male connector on the other.

This isn’t just any cable—it’s your ticket to superior signal integrity in demanding environments like base stations, broadcast towers, or high-power amateur radio rigs.

Why Choose Our LL400 Cable? Here’s the Edge You Need:

• Ultra-Low Attenuation for Maximum Range: Engineered as a direct equivalent to industry gold standards like LMR-400 and Belden 9913, this 50-ohm coax delivers whisper quiet signal transmission with attenuation as low as 0.95 dB at 50 MHz for a 125-foot run. Keep every watt where it counts—no more wasted power down the line.

• Rugged Durability That Lasts: Wrapped in a flexible, UV-resistant polyethylene jacket with a 10mm outer diameter, it’s built to withstand harsh outdoor conditions—think extreme weather, abrasion, and constant flexing. Users report zero jacket deterioration even after years of exposure, ensuring a 20-year service life.

• Seamless Connector Compatibility: The 4.3-10 Male end offers low-PIM (Passive Intermodulation) performance and secure locking for high-vibration installs, perfect for modern cellular and broadcast gear. Pair it effortlessly with your SMA-equipped devices like antennas, routers, or test equipment via the SMA Male end—true plug-and-play versatility.

• Lightweight & Flexible for Easy Handling: At just a fraction of the weight of bulkier alternatives like RG-213, it’s a dream for mobile setups, rooftop mounts, or quick jumps. No more wrestling with stiff cables during installation.

Whether you’re a pro engineer optimizing a DAS (Distributed Antenna System), a ham radio enthusiast chasing DX contacts, or a network admin demanding zero downtime, this LL400 assembly is your reliable backbone. It’s trusted by heavy hitters like HAARP for mission-critical ops and delivers the same rock-solid performance as LMR-400 without the premium price tag.
