Bolton240 Low-Loss Cable – Reliable Signal Transfer, Built for Tough South African Conditions



Don’t let poor-quality cables choke your signal performance. The Bolton240 Low-Loss Coaxial Cable is your go-to solution for maximizing signal transmission between antennas and boosters - whether you’re boosting signal in a rural farmhouse, coastal lodge, inner-city office, or remote mining site.

Why choose Bolton240? Unlike standard coaxial cables that often degrade signal over distance, Bolton240 is engineered with ultra-low-loss shielding and durable construction to preserve signal strength across long runs. With high-quality N-Male and SMA-Male connectors, this 50-ohm coax cable minimizes signal drop-off and ensures a reliable connection between components in your signal boosting setup. Expect exceptional performance with minimal attenuation - ideal for outdoor or indoor use in setups where every decibel matters.

Key benefits: Ultra-low-loss design ensures maximum signal transfer over distances, reducing the performance drop you’d typically see with lower-grade cables. Factory-terminated with N-Male and SMA connectors for seamless integration with most signal boosters, antennas, and routers - including WilsonPro, weBoost, and many popular modems. Heavy-duty weather-resistant jacket protects against UV, moisture, and temperature extremes - built to withstand South Africa’s harsh environments. Flexible and easy to install, whether routed indoors, through walls, or externally along rooftops and poles.

Perfect for: Boosting cellular signal in homes, lodges, farms, offices, warehouses, or industrial sites. Extending cable runs without compromising signal integrity. Creating professional-grade signal setups where reliability is non-negotiable

Whether you’re extending an antenna setup on a steel-roofed warehouse or optimizing signal distribution in a remote game lodge, Bolton240 Cable gives your booster system the robust, high-performance link it needs. For stable signal transmission you can trust, even across long distances, there’s no better connection.

Product FAQ

1 What devices is this cable compatible with?

The Bolton240 cable with N-Male to SMA-Male connectors is compatible with most 50-ohm signal boosters, antennas, and cellular routers. Commonly used to connect outdoor donor antennas (N-Female ports) to signal boosters (SMA-Female ports), or from boosters to modems/routers like Pepwave, MoFi, and Teltonika.

2 What does N-Male to SMA-Male mean?

These are connector types:

N-Male: A larger threaded connector that screws onto an N-Female port (common on antennas)

SMA-Male: A smaller threaded connector that screws onto an SMA-Female port (found on boosters/routers)

This combination allows you to bridge between different equipment types commonly found in booster setups.

3 Is the cable pre-terminated or do I need to crimp it myself?

The Bolton240 cable is professionally pre-terminated at the factory with precision-crimped N-Male and SMA-Male connectors, using specialized tools for a perfect fit and low insertion loss. No crimping or additional tools required. Just plug and play.

4 What length options are available?

Bolton240 cables are available in standard lengths such as:

3m, 5m and 10m

Custom lengths may also be available on request, depending on stock and project needs.

5 Can I use this with a 75-ohm booster or TV antenna system?

No. This cable is 50-ohm and designed specifically for cellular signal boosting and networking equipment. It is not compatible with 75-ohm systems like TV antennas or consumer coaxial gear (e.g., RG6).
