Bolton400 LMR400 Equivalent Coaxial Cable 100ft - Ultra Low Loss

In this review the Bolton400 100 ft coaxial cable is evaluated for installers and hobbyists who need a long, reliable 50 ohm run for cellular boosters and WiFi repeaters. The bottom line: it delivers professional-grade signal transfer with very low loss over 100 ft, making it a strong choice when distance and signal retention matter. The review focuses on practical installation experience, loss performance, connector quality, and where this cable fits compared with typical LMR400 replacements.

Key Features

• 50 Ohm compatibility: Works with any 50 ohm RF system so it can be used with cell phone boosters, WiFi repeaters and a wide range of antennas without impedance mismatch.
• LMR400 equivalent loss: Rated at about 6 dB loss per 100 ft, the cable keeps signal attenuation low across a typical long run to preserve booster performance.
• N-Male to N-Male connectors: Fitted with N-male on both ends for secure, weather-resistant connections to most outdoor and indoor booster equipment.
• Pro-grade construction: CL3 rated and triple-shielded with an insulated interior, it handles up to 300 volts and stands up to commercial building installations.
• Universal carrier support: Works with all North American carriers and a wide range of devices, from smartphones to hotspots and dedicated cellular equipment.
• Support and warranty: Includes lifetime technical support, a 30-day money-back guarantee and a one-year warranty for added confidence.

Who It's For

This cable is best for professional installers, building technicians and serious DIYers who need a reliable 100 ft run between an outdoor antenna and an indoor signal booster or repeater. The low-loss LMR400 equivalent construction makes it suitable where preserving signal over distance is important.

Those looking for very flexible or ultra-lightweight coax for frequent handling or extremely compact routing might prefer a different, more flexible type; similarly, if runs are under 20 ft the loss advantage is less critical and a lighter cable may be easier to work with.

Pros & Cons

Pros

• Low loss for long runs, preserving cellular signal strength across 100 ft.
• Solid N-male connectors and triple shielding give durable, professional connections.
• CL3 rating and 300 V capacity make it acceptable for commercial building installations.
• Broad device and carrier compatibility plus lifetime technical support.

Cons

• Stiffer construction can make tight routing or frequent handling more difficult for some installers.
