N Male to N Male Coaxial Cable 50ft (3D-FB) with N-N and N-SMA Adapters
Quick take
This 50 ft 50-ohm coaxial cable is designed to extend the antenna-to-booster connection for 4G LTE and 5G setups. It uses N-type male connectors and includes adapters so you can adapt to common booster and antenna port types. The key caveat is that longer coax runs still introduce measurable signal loss at cellular frequencies, so cable length and placement matter as much as the cable itself.
Pros and cons
Pros
- 50-ohm cable aimed at stable performance with compatible cell signal booster systems.
- N-type connectors for outdoor antenna style installs, plus included adapter options.
- Made for indoor and outdoor routing, with weather-resistant insulation and shielding.
- More “in-between” loss than very basic RG58-size coax, while still staying manageable for routing through tighter openings.
Cons
- At 50 ft, attenuation can still be significant at cellular frequencies, so it may not suit every “max distance” goal.
- Designed for fixed installs more than frequent flexing, since solid-core coax can be stiffer.
- Connector durability depends on proper installation practices (use appropriate waterproofing/treatment around outdoor connections).
What buyers think
Buyer feedback is generally positive and focuses on practical setup outcomes, build quality, and connector usefulness. Several comments highlight that the cable works well when plugged into a cell booster system and helps improve signal bars in real-world use. Reviewers also call out the included adapters as a helpful way to match different booster and antenna ports, which reduces the hassle of hunting for separate parts. There is also recurring discussion of the tradeoff between cable thickness, routing flexibility, and signal loss, with the overall impression that this cable lands in a reasonable middle ground for people who want better performance than basic RG58-style coax without moving up to very large, harder-to-route alternatives.
How to think about this 50 ft coax extension
The most important question is not just “Does it fit my ports?” but “How much signal loss can your setup tolerate at the length you need?” At cellular frequencies, even a well-matched coax cable will add attenuation. If your antenna placement is already borderline, adding 50 ft of coax may reduce the benefit you were trying to gain.
This model is built as a 50-ohm coax extension intended for booster and outdoor antenna connections. It supports a wide cellular frequency range (about 700 MHz through 2700 MHz), making it suitable for many common 4G LTE and 5G band use cases, assuming your booster and antenna are compatible.
Key specs that affect buying decisions
Connector fit and included adapters
You get a N male to N male coaxial cable, intended to mate with N-type female ports on compatible boosters and antennas. The bundle also includes an N female-to-female coupler and an N Female-to-SMA Male adapter, which can be useful when you need to extend or adapt a mixed connector system. The practical takeaway, based on common buyer notes, is that the adapters reduce “one wrong connector” problems during installation.
Impedance and performance goal
The cable is specified as 50 ohm, which is the standard impedance used in many RF systems, including typical signal booster antenna runs. Reviewers describe it as a low-loss option for its size category, with comments comparing it favorably versus RG58-style coax for cellular use. Still, expect the real-world result to depend heavily on length, frequency, and overall system design.
Routing through walls, attics, basements, and outside runs
This cable is positioned for both indoor and outdoor installation. It uses weather-resistant construction with shielding designed to resist moisture and outdoor conditions.
Pros and cons for different buyer types
Best for
- Home, garage, camper, or rural booster setups where you need an extra 50 ft run from booster equipment to a higher or better-positioned antenna.
- Installers who want N-type connectors for typical outdoor antenna hardware.
- Anyone who values included adapter flexibility (N-N coupling and N to SMA) to match different port configurations.
- Buyers aiming for “better than basic RG58-size coax,” while avoiding the hassle of very large low-loss cables.
Who should avoid it
- If you need the absolute lowest attenuation over long runs, you may have to consider thicker, lower-loss coax alternatives (for example, larger LMR-class cable types), because 50 ft still adds loss.
- If your application requires constant flexing (frequent repositioning), stiffer solid-core coax can be less convenient than more flexible cable designs.
- If you are unsure about connector types on your booster and antenna, double-check port genders and standards before buying, because the cable’s base connector type is N male to N male.
Verdict: is it worth it?
For most people extending a compatible cell signal booster to an exterior antenna, this 50 ft 50-ohm N-to-N coax is a practical, well-fitted option, especially because the included adapters help you adapt connectors without extra shopping. The main limitation is the physics of long coax runs: at cellular frequencies, attenuation can meaningfully affect performance. If your antenna placement can compensate, this cable can be a good value-in-size tradeoff; if you need “every last dB,” you will likely want a thicker lower-loss coax solution instead.

FAQ
Will this cable work with my cell signal booster?
It’s intended for cell signal booster and outdoor antenna connections using N-type male ports. If your booster and antenna ports match N-type standards (and any additional adapters you need), it should integrate cleanly. If your booster uses different connector types, the included N-N coupler and N-to-SMA adapter may help, but confirm port genders and standards first.
Is 50 ft too long for a cellular signal booster setup?
50 ft can still introduce noticeable attenuation at cellular frequencies. Whether it’s “too long” depends on your signal conditions and antenna placement. If your area is already marginal, the additional loss may reduce the benefit you were expecting.
What adapters are included?
The kit includes an N female-to-female coupler and an N Female-to-SMA Male adapter, in addition to the N male to N male cable itself.
Can I use it outdoors?
Yes, it is built for indoor and outdoor routing, with weather-resistant insulation and shielding. For outdoor installations, treat and protect the coax connections properly (for example, use appropriate waterproofing at connector interfaces) so moisture does not compromise the setup.
How flexible is this coax for routing?
It is designed to be routed through spaces like walls, attics, basements, and rooftops. One review theme is that this cable is on the stiffer side compared to more flexible coax, which can be better for fixed installs and less ideal if the cable needs to be frequently flexed.
What frequencies does it support?
It’s listed for common cellular bands spanning approximately 700 MHz up to 2700 MHz, covering many 4G LTE and 5G use cases when paired with compatible booster and antenna hardware.
