CablesOnline 50ft UHF PL259 to UHF PL259 RG316 Cable - Low Loss Coax

In this review the CablesOnline 50ft UHF PL259 Male to UHF PL259 Male RG316 coaxial cable is evaluated for users who need a slim, high-temperature 50-ohm interconnect for radio and antenna projects. The bottom line: this cable delivers flexible, low-loss performance in a compact 0.1in diameter jacket, making it a good choice where space and routing are limited. The review highlights the construction, connectors, and real-world suitability so a buyer can decide if this UC150 cable fits their setup and signal needs.

Key Features

• Gold plated UHF PL259 connectors: Both ends have gold plated contacts to improve conductivity and reduce corrosion for more reliable connections over time.
• 50 Ohm RG316 low loss core: The RG316 dielectric and conductor are optimized for 50-ohm systems, helping maintain signal integrity for radio and RF use.
• Slim 0.1in outside diameter: The 2.5mm cable profile makes routing through tight spaces and cable bundles easier than bulkier coax options.
• High temperature FEP jacket: The FEP jacket withstands elevated temperatures and remains flexible for installations near heat sources or in compact enclosures.
• 50 ft length: The single 50ft length gives ample reach for many antenna placement or equipment layout needs without splices.

Who It's For

The cable suits amateur radio operators, shortwave listeners, and home audio or electronics hobbyists who need a durable 50-ohm interconnect with PL259 terminations and a slim profile. It is especially useful when cable runs require bending around tight corners or threading through conduit where a thicker coax would be difficult to fit.

Users who require ultra-low loss for long-distance professional links or weatherproof outdoor permanent mast installations should consider heavier, specialized coax designed for those environments. This product is best for indoor or protected outdoor use where flexibility and a compact diameter are priorities.

Pros & Cons

Pros

• Gold plated PL259 connectors provide reliable electrical contact and resist corrosion.
• Slim RG316 cable design eases routing and installation in confined spaces.
• High temperature FEP jacket improves durability around heat sources and maintains flexibility.

Cons

• The thin 2.5mm diameter is less mechanically robust than larger coax and may not be ideal for heavy outdoor exposure.

Specifications

Our Verdict

The CablesOnline 50ft RG316 UC150 cable is a sensible, value-focused option for radio enthusiasts and hobbyists who need a slim, flexible 50-ohm lead with PL259 terminations. Its gold plated connectors and FEP jacket make it a reliable indoor or protected-use cable where space is limited, though those needing heavy-duty outdoor longevity should choose a thicker outdoor-rated coax. Overall it offers good performance for its intended use and length.

Frequently Asked Questions

Is this cable suitable for antenna connections?
Yes; the cable is 50 ohm RG316 with UHF PL259 male connectors and is suitable for many antenna and radio connections in indoor or protected installations.

Can it be used outdoors?
The FEP jacket is heat resistant, but the slim RG316 construction is best for protected outdoor use; for permanent exposed mast installations a heavier outdoor-rated coax is recommended.

Will the slim diameter affect signal loss?
The RG316 is described as low loss for its class, but thinner coax will generally have higher loss than larger low-loss types over long distances, so 50 ft is reasonable for typical radio use.
