GEMEK 36ft SMA Male to N Male Cable - Low Loss S-MR400 Extension

In this review of the GEMEK 36ft SMA Male to N Male Cable the bottom line is straightforward: this is a purpose-built, low-loss coax extension for installers who need reliable 50 ohm connections between SMA-equipped radios and N-connector antennas. The reviewer found its S-MR400 construction and robust gold-plated connectors deliver noticeably better signal retention on long runs, making it a solid choice for cellular, LTE, ADS-B and WiFi booster setups where length and low loss matter.

Key Features

• Connector type: SMA Male to N Male connectors allow direct connection from SMA-equipped modems and radios to standard N-antenna ports without adapters.
• Cable construction: Double-shielded S-MR400 coax preserves signal over the 36 ft length, reducing loss compared with thinner 50 ohm jumpers.
• Length and impedance: The 36 ft (11 m) length with 50 ohm impedance makes it suitable for many external antenna placements where distance from the device is required.
• Durability: Gold plated connectors and heat-shrink on both ends provide a secure, corrosion-resistant connection for indoor and sheltered outdoor installations.
• Compatibility: Works with a wide range of SMA female to N female equipment including modems, routers and repeaters from common networking brands.
• Mechanical flexibility: A minimum bending radius of about 2.44 in lets installers route the cable around obstacles without kinking the center conductor.

Who It's For

This cable is aimed at technicians, hobbyists and small installers who need a long, low-loss 50 ohm link between SMA-equipped radios or signal boosters and N-connector antennas. It is especially useful for cellular LTE, 3G/4G/5G setups, ADS-B receivers and WiFi booster systems that benefit from a larger center conductor and heavier coax for runs up to several dozen feet.

People who should look elsewhere include those needing TV coax (this is not for TV), anyone requiring RP-SMA or F-type connectors, or users who need a weatherproof outdoor-rated coax with specialized jacketing for permanent rooftop exposure.

Pros & Cons

Pros

• Solid build with gold plated SMA and N male plugs that make reliable electrical contact.
• Low-loss S-MR400 construction retains more signal on 36 ft runs compared with smaller 50 ohm jumpers.
• Compatible with a broad set of modems, routers and repeaters that accept SMA to N connections.
• Flexible enough to bend around tight corners thanks to a small minimum bending radius.

Cons

• Not intended for TV or F-type systems, so it is not universal for all coax needs.
• Not an RP-SMA or female-to-female adapter, so adapter purchases may be required for other connector types.

Frequently Asked Questions

Is this cable suitable for TV antenna connections?
No. This cable is 50 ohm S-MR400 intended for RF, cellular and data applications and is not designed for standard TV or F-type connections.

Will it work with my router or modem?
Yes, it is compatible with equipment that uses SMA female to N female interfaces, including many modems, routers and signal boosters from popular vendors.

Can it be routed in tight spaces?
Yes. The cable has a minimum bending radius of about 2.44 in and allows 90 degree bends in a short distance without damaging the center conductor.
