GEMEK 10ft N Male to SMA Male Cable

Bottom line: The GEMEK 10ft N Male to SMA Male Cable ($19.98 on Amazon as of 2026-10-20 22:24 UTC): LMR-240-size 0.240 in coax with a larger center conductor than thin jumpers; main trade-off: fixed 10ft length: too long for tight jumpers, too short for long runs.

Pros & Cons

Pros

  • ✓ LMR-240-size 0.240 in coax with a larger center conductor than thin jumpers
  • ✓ Double-shielded 50 ohm build to reduce interference on RF runs
  • ✓ All-copper, gold-plated SMA male and N male connectors with heat shrink
  • ✓ Coils to a 1.5 in minimum diameter; 90 degree bends in 1 in or less
  • ✓ Rated -40°C to +85°C for indoor or enclosure installs

Cons

  • ✗ Fixed 10ft length: too long for tight jumpers, too short for long runs
  • ✗ Standard SMA male, so it will not mate with RP-SMA router ports
  • ✗ Both ends are male; your gear needs SMA female and N female ports
  • ✗ Thinner than LMR-400, so it loses more signal on long runs

Manufacturer description

The GEMEK 10ft SMA Male to N Male cable connects SMA-equipped gear to N-style antennas over a short, low-loss run. Typical uses include a cellular modem, WiFi router, GPS receiver or signal booster repeater. The coax is double-shielded, 50 ohm, LMR-240-size cable called KMR240, with a 0.240 inch diameter. Its larger center conductor holds signal better at higher frequencies than thin RG-style jumpers. Both ends use all-copper, gold-plated connectors, with heat shrink at each end where the cable meets the connector. The cable is rated from -40°C to +85°C. It coils down to a 1.5 inch minimum…

SpecPicks Verdict

SpecPicks scored GEMEK 10ft N Male to SMA Male Cable using a rating × review-volume × price-fit model applied to published specs and reviews across the cables & connectors category. GEMEK's cables & connectors lineup sits within the broader category mid-tier; price and specs are the deciding factors over brand loyalty here. Judge it on the specification table and the price rather than on sentiment: check the figures that decide your use case, then put it side-by-side with two or three close alternatives in the Compare tool before clicking through.

Common buyer scenarios for cables & connectors of this kind: matching it to an existing build, replacing a failing part, or upgrading from a previous-generation equivalent. Check the spec table below against your current setup — particularly socket / form-factor / power-rating fields — and confirm compatibility on the retailer's listing before purchase. Prices and stock are set by the retailer and may have moved since this page was last updated.

Frequently Asked Questions

Will this cable work with an RP-SMA WiFi router?

No, not directly. One end is a standard SMA male plug, which needs a standard SMA female jack. Many consumer WiFi routers use RP-SMA, so check your router's connector before you buy, or add an RP-SMA adapter.

What connectors does my equipment need to use this cable?

Your device needs an SMA female port and your antenna or booster needs an N female port. The cable has an SMA male plug on one end and an N male plug on the other, both 50 ohm.

How far can I run LMR-240-size cable before signal loss becomes a problem?

Per GEMEK, LMR-240-size coax works well for WiFi and cellular runs up to 25-30 feet, and for HF/VHF/UHF installs up to 150 feet. This 10ft cable is well inside the WiFi and cellular range.

Can I route this cable around tight corners?

Yes. The listed minimum coiling diameter is 1.5 inches, and the cable can make a 90 degree bend in one inch or less without loss.

Is this cable suitable for outdoor or cold-weather use?

The cable is rated from -40°C to +85°C, and both ends have heat shrink. The listing does not give a waterproof rating, so seal outdoor connections with weatherproofing tape or a boot.
