Proxicast 25 ft SMA Male to SMA Female Low-Loss Coax Cable - Reliable

In this review of the Proxicast 25 ft SMA Male to SMA Female coax cable, the bottom line is simple: it is a practical extension for anyone who needs extra reach between SMA antennas and cellular modems or routers. The biggest reason to buy is the use of very low-loss LMR195-size 50-ohm coax that preserves 4G and 5G signal strength over 25 ft, making it a solid choice for installations where signal retention matters. The cable is built with gold-plated signal pins and heat shrink on both ends, which gives it a professional finish and reliable connections on common SMA-based devices.

Key Features

• SMA male to SMA female: Lets you connect an antenna directly to a modem or extend an existing SMA cable without adapters, simplifying setup.
• 25 ft low-loss cable: The LMR195-size 50-ohm conductor minimizes signal loss over distance so cellular and GPS reception stays strong across the run.
• Pro-grade construction: Gold plated signal pins and heat-shrinked ends improve corrosion resistance and provide a durable, neat termination.
• Wide compatibility: Works with many SMA-based devices and antennas from major router and modem brands, reducing compatibility headaches.
• Extension capability: Functions as both a jumper and an extension cable so it can add length to existing SMA coax runs without extra conversion pieces.

Who It's For

The cable is best for installers, hobbyists, and small business users who need to relocate an external antenna or extend the lead to a 4G/5G modem, router, or single-board receiver. It serves well in fixed installations, mobile setups in vehicles, and ham or ADS-B receiver rigs where a cleaner, longer run is required.

It is not aimed at TV or WiFi applications, and users who need bulkier, lower-loss cable types for very long commercial runs should look elsewhere. Also, those requiring different connector genders or N-type terminations will need a different part or adapters.

Pros & Cons

Pros

• Low-loss LMR195-size 50-ohm construction preserves cellular and GPS signal quality over 25 ft.
• Gold-plated signal pins and heat shrink on both ends provide a durable, professional connection.
• Direct SMA male to SMA female wiring makes it simple to extend or join SMA devices without adapters.

Cons

• Connector quality received mixed feedback from some customers, so installers should verify tight seating on their specific gear.
• Not suitable for TV or WiFi use and not the lowest-loss option for very long commercial coax runs.

Specifications

Our Verdict

The Proxicast 25 ft SMA male to SMA female low-loss coax cable is a practical, good-value option for anyone extending or relocating SMA antennas for cellular and GPS equipment. It balances manageable flexibility with LMR195 low-loss performance and pro-grade terminations, making it a dependable choice for installers and hobbyists who need clean, longer runs without significant signal degradation.

Frequently Asked Questions

Will this cable work with my router or modem?
Yes, it is compatible with SMA-based devices from many manufacturers and is intended for cellular modems and routers that use SMA connectors.

Can I use this for TV or WiFi antennas?
No, this cable is specified for 4G/5G, ham, ADS-B, and GPS and is not intended for TV or WiFi use.

How much signal loss should I expect over 25 ft?
Loss is minimized by the LMR195-size 50-ohm construction, so signal degradation is low compared with thinner cables, but exact loss depends on frequency and system setup.
