SMA Male to SMA Male Cable Low Loss RF Coax Lead

Connect Your Antenna Without Sacrificing Signal

A quality antenna is only as good as the cable connecting it.

This low-loss SMA Male to SMA Male RF cable is designed to help maintain signal quality between compatible antennas and communication equipment, making it ideal for longer cable runs where every decibel matters.

Perfect for:

• 4G internet
• 5G internet
• Cellular routers
• Mobile broadband
• Signal boosters
• IoT devices
• RF equipment
• Replacement antenna cables

Don't Let Your Cable Reduce Your Signal

Even the best antenna can't perform properly if signal is lost through poor-quality cable.

A low-loss RF cable helps:

• Preserve signal strength
• Reduce attenuation
• Improve connection stability
• Maximise antenna performance
• Support higher-frequency applications like 4G and 5G

• Direct RF device-to-device connection
• Connects SMA-equipped antennas, routers, modems, and RF equipment
• Ideal for short-range, low-loss signal linking
• SMA male to SMA male (both ends)
• Compatible with: 4G / 5G routers, Signal boosters (Cel-Fi style systems), SDR, IoT, and RF test equipment
• Optimised for stable signal performance
• Designed for 50Ω RF systems
• Supports frequencies typically up to 6 GHz (LTE / 4G / 5G range)
• Maintains clean signal transfer for short runs
• Low-loss coaxial construction
• Built using low-loss 50-ohm RF coax (commonly LMR195 / LL195 class or
• quivalent)
• Reduces signal degradation compared to standard RG58 cables
• Ideal for maintaining modem-to-antenna performance
• Balanced 2m length
• Perfect “in-between” size for: Desk or cabinet installations, Short antenna extensions, Indoor RF equipment setups
• Avoids excess slack while maintaining flexibility
• Flexible and installation-friendly
• Soft, bend-friendly coax for easy routing
• Suitable for tight spaces behind routers or inside comms racks
• Durable RF-grade build
• Shielded construction helps reduce:
• EMI (electromagnetic interference)
• Signal noise
• Designed for reliable long-term use
• Plug-and-play installation
• Screw-on SMA connectors
• No tools or termination required

Typical applications

• 4G / 5G home internet setups
• External antenna extensions
• IoT and telemetry systems
• RF testing and lab environments

Confirm Your Connector Type Before Ordering

This cable is designed for equipment using standard SMA connectors.

Many networking devices use RP-SMA connectors, which look similar but are not compatible.

If you're unsure, send us a photo of your device and we'll help confirm the correct cable before you purchase.

Get the Most From Your External Antenna

This cable is ideal for connecting compatible external antennas to:

• 4G routers
• 5G routers
• Cellular modems
• Signal boosters
• Fixed wireless systems
• Industrial communication equipment

A quality low-loss cable helps ensure the signal collected by your antenna reaches your equipment as efficiently as possible.

Will this work with my 4G or 5G router?

Yes, provided your router and antenna both use standard SMA Male-compatible connections.

What's the difference between SMA and RP-SMA?

Although they look very similar, they're different connector types and are not directly compatible. Always confirm your connector type before ordering.

Can I use this with a Cel-Fi repeater?

It may be suitable for compatible Cel-Fi or other RF equipment using standard SMA connections. Always check the connector type on your device first.

Why choose a low-loss cable?

Lower-loss cable helps minimise signal attenuation between your antenna and equipment, which is especially important at 4G and 5G frequencies and on longer cable runs.
