Coaxial Cable YWDXpek 75-1.05/4.8 K-1000 100m — 75 Ω, 1.05 mm conductor, 4.8 mm diameter

Coaxial Cable YWDXpek 75-1.05/4.8 K-1000 in a 100 m roll is a 75 Ω signal cable with a 1.05 mm solid central conductor and an overall diameter of 4.8 mm. It is intended for RF, television and antenna installations where consistent characteristic impedance and adequate shielding are required. The cable supports medium-distance feeder runs and fixed indoor or outdoor cabling for TV distribution, antenna feeders and other 75 Ω signal paths.

Advantages

This 75 Ω coaxial cable offers a balanced combination of conductor size and overall diameter to maintain signal integrity and reduce loss across typical TV and RF frequencies. The cable construction provides shielding and dielectric properties suitable for consistent impedance, helping to minimise reflections and maintain stable transmission. Supplied on a 100 m roll, it is practical for continuous feeder runs and simplifies installation planning for residential and small commercial projects.

Suitable for

• Antenna feeder lines for TV and radio systems
• Indoor and outdoor fixed cabling for television distribution
• Connecting set-top boxes, splitters and wall sockets in 75 Ω systems
• Short to medium-length RF signal runs where a 75 Ω characteristic impedance is required

When it may not be suitable

This cable is not intended for applications requiring extremely low loss over long distances such as professional RF trunk lines or long cable runs between broadcast sites. It may also be unsuitable where a more flexible, smaller-diameter jumper cable or a larger, lower-loss coax (e.g., with a larger conductor and thicker shielding) is specified by system designers.

Key specifications

• Characteristic impedance: 75 Ω
• Central conductor diameter: 1.05 mm
• Overall cable diameter: 4.8 mm
• Length: 100 m (single roll)
• Typical application: RF, TV and antenna feeder installations

How to use

Measure the required run length and cut the cable from the roll allowing extra length for connectors and routing. Strip the outer jacket, braid and dielectric according to the connector manufacturer’s instructions to expose the central conductor and prepare the shield. Use compatible 75 Ω connectors and crimp or compress fittings to maintain the characteristic impedance. Route the cable avoiding tight bends and sharp edges; secure it with appropriate clips or ties and protect outdoor sections from prolonged direct sunlight and mechanical stress.

What to consider before purchase

• Required run length and whether 100 m on a single roll matches installation needs
• Compatibility with the chosen 75 Ω connectors and connector assembly method
• Environmental exposure: verify suitability for outdoor installation and consider additional UV or moisture protection if necessary
• Signal loss expectations for the planned run length and whether a lower-loss cable is needed for longer distances

Usage recommendations

For best performance use proper 75 Ω connectors and avoid sharp bends; terminate both ends correctly to preserve impedance and minimise reflections. For outdoor runs, route the cable through conduit or use additional protective sleeving where exposed to mechanical wear or prolonged sunlight.
