The Professional's Choice for Long-Run, Low-Loss RF Interconnects
In professional RF installations — from amateur radio base stations to commercial broadcast sites — signal loss over distance is the enemy. Traditional RG8 and RG213 cables simply cannot match the attenuation performance of modern LMR-400 coaxial cable. Our N-Type Female to UHF Male (PL-259) LMR-400 cable assemblies are engineered for installers and engineers who demand maximum signal integrity over extended cable runs.
Why LMR-400 Dominates Long-Run Applications
LMR-400 features a foam PE dielectric that reduces signal attenuation by up to 40% compared to solid-dielectric cables like RG213. At 400 MHz, LMR-400 exhibits only 2.2 dB loss per 100 feet — compared to 3.9 dB for RG213. This translates directly to stronger received signals, more effective transmitted power, and extended communication range. For tower installations, remote antenna systems, and any application where cable length exceeds 10 meters, LMR-400 is the undisputed industry standard.
Bridging Modern Precision with Legacy Reliability
The N-Type connector, originally designed for military applications, offers a precision 50 Ohm interface rated to 6 GHz with excellent weather sealing. The UHF PL-259 connector, while optimized for HF/VHF frequencies, remains the most widely deployed connector in amateur radio, marine communications, and CB installations worldwide. This cable assembly bridges these two worlds — enabling you to connect modern spectrum analyzers, vector network analyzers, and base station radios to established UHF antenna infrastructure without adapters or signal degradation.
Engineered for Field Durability
Manufactured by our senior RF engineering team with over 20 years of hands-on experience, these assemblies are built to survive harsh field conditions. The N-Type Female connector features a precision-machined brass body with gold-plated contacts for corrosion resistance. The PL-259 male connector is solder-crimped for maximum mechanical strength. The LMR-400 cable's PE jacket is UV-stabilized for direct outdoor exposure and can withstand temperature swings from -40°C to +85°C.
● Amateur Radio Base Stations: Connecting HF/VHF/UHF transceivers with N-Type outputs to external UHF antenna systems, antenna tuners, and tower-mounted amplifiers.
● Commercial Two-Way Radio: Extending repeater site feedlines from N-Type equipped repeaters to UHF antenna arrays on towers and rooftops.
● Broadcast & Transmission: Low-loss interconnection between exciters, amplifiers, and antenna systems in FM/TV broadcast installations.
● Test & Measurement: Creating low-loss extension cables from N-Type equipped spectrum analyzers, signal generators, and VNAs to UHF test fixtures.
● Marine Communications: Routing long cable runs from below-deck radios to masthead antennas on commercial vessels and yachts.
● Cellular & DAS: Distributed Antenna System (DAS) feedlines connecting N-Type equipped signal sources to UHF distribution points.
● Satellite Ground Stations: Low-loss feedlines from satellite receivers to outdoor antenna systems.

Q1: Why choose LMR-400 over RG213 for my antenna feedline?
A: LMR-400 offers approximately 40% less signal loss than RG213 at UHF frequencies while maintaining the same 10.3mm outer diameter. This means stronger signals at your antenna, better receive sensitivity, and extended communication range — especially critical for runs over 10 meters or at frequencies above 100 MHz.
Q2: Can this cable handle high power from my amplifier?
A: Yes. LMR-400 is rated for up to 1,500W CW at HF frequencies and 500W+ at UHF. The foam PE dielectric and large center conductor handle high power levels efficiently with minimal heating. Always ensure proper ventilation and connector torque specifications for high-power applications.
Q3: Is the N-Type Female connector weatherproof for outdoor use?
A: Yes. The N-Type connector is inherently weather-resistant due to its threaded coupling and precision-machined surfaces. For long-term outdoor exposure, we recommend applying self-amalgamating weatherproofing tape over the mated connection to create a fully sealed, moisture-proof barrier.
Q4: Can I use this cable for WiFi or 2.4GHz applications?
A: While the N-Type connector is rated to 6 GHz, the UHF (PL-259) connector is optimized for frequencies below 300 MHz. For 2.4GHz WiFi applications, we recommend an N-Type to N-Type or N-Type to SMA cable assembly using LMR-400 to maintain full frequency performance.
Q5: Do you provide test reports with orders?
A: Yes. We can provide VSWR and insertion loss test reports generated by our Rohde & Schwarz and Anritsu VNAs for bulk orders upon request. Sample orders include basic QC verification.
Q6: What's the minimum bend radius for LMR-400?
A: LMR-400 has a minimum bend radius of 38mm (1.5 inches) for single bends and 102mm (4 inches) for repeated bends. This is more flexible than traditional RG8 cables, making it easier to route through conduit and around corners during installation.
