Description
Premium 50-Ohm N-Male Crimp RF Connector
Commercial-grade 50-Ohm N-Male coaxial connector engineered for low-loss RF feedlines, antenna installations, repeaters, and base stations.
The Purchase Radios N-Male Coaxial RF Connector is a high-performance 50-Ohm crimp connector designed to provide reliable, low-loss RF signal transfer across two-way radio base stations, repeater systems, bidirectional amplifiers (BDAs), cellular boosters, and wireless infrastructure. Built with a precision nickel-plated brass housing, a gold-plated center pin, and a durable PTFE (Teflon) dielectric insulator, this N-type male connector maintains stable electrical impedance and superior shielding performance from DC up to 11 GHz.
Engineered for field technicians and radio system integrators, the Purchase Radios N-Male Coaxial RF Connector features a heavy-duty threaded coupling mechanism with an internal silicone seal to prevent water ingress and corrosion in outdoor tower or rooftop installations. Available in two cable-size variants—supporting 400-series large coax (LMR-400, RG-213, RG-8) and 195/200/58-series small coax (RG-58, LMR-195, RG-142)—this connector ensures low Voltage Standing Wave Ratio (VSWR) and high power handling across land mobile radio (LMR) frequencies governed by FCC Licensing and DMR Association standards.
Key Features & Benefits
-
50-Ohm Constant Impedance: Optimized for low insertion loss and high signal efficiency across DC to 11 GHz frequency ranges.
-
Precision Nickel-Plated Brass Body: Corrosion-resistant plating protects against harsh outdoor elements and repeated mating cycles.
-
Gold-Plated Center Pin: Superior conductivity pin design prevents oxidation and minimizes signal attenuation at high RF power levels.
-
High-Temperature PTFE Insulator: Premium Teflon dielectric tolerates elevated soldering heat and extreme environmental temperatures.
-
Weatherproof Silicone Seal: Internal O-ring inside the threaded coupling nut protects cable terminations from moisture penetration.
-
Secure Crimp Outer Ferrule: Heavy-duty crimp collar provides maximum cable retention force to withstand wind load and cable pull.

Frequently Asked Questions
What is the difference between the two N-Male connector variants?
The two variants differ in their entry collar diameter and crimp ferrule size. The LMR-400 variant accommodates larger 0.400" outer diameter cables (LMR-400, RG-8, RG-213), while the RG-58 variant fits 0.195"–0.200" outer diameter cables (RG-58, LMR-195, RG-142).
Are these Purchase Radios N-Male connectors waterproof?
Yes, the connector coupling nut contains an internal silicone gasket that forms a weather-resistant seal against female N-connectors. For permanent outdoor installations, weatherproofing tape over the crimp collar is recommended.
What impedance are these N-Male connectors rated for?
These connectors are rated for a constant 50-Ohm impedance, making them ideal for commercial LMR, PMR, cellular, and Wi-Fi RF transmission systems.
Is soldering required for installation?
The outer braid and jacket are secured using a standard hexagonal crimp ferrule. The center pin can be soldered or crimped using a standard precision RF pin crimper depending on installer preference.
Can these connectors be used on 75-Ohm TV cables?
No, these are 50-Ohm RF connectors designed specifically for commercial two-way radio and wireless telecommunications coax. Using them with 75-Ohm video or CATV cables will cause impedance mismatches.
