Pros & Cons

Pros

  • ✓ 36 ft of double-shielded KMR240 (LMR240-size, 0.240 in) 50 ohm coax
  • ✓ All-copper, gold plated SMA male and N male connectors with heat shrink on both ends
  • ✓ Bends 90 degrees in 1 inch or less; 1.5 in minimum coiling diameter
  • ✓ Rated -40°C to +85°C for outdoor, mast and attic antenna runs
  • ✓ Rated for HF/VHF/UHF installs up to 150 ft, so 36 ft is well within range

Cons

  • ✗ 36 ft exceeds the 25-30 ft LMR240 sweet spot GEMEK cites for WiFi/cellular
  • ✗ Male-to-male only; your gear needs SMA female and N female ports
  • ✗ Standard SMA, not RP-SMA; check your router's antenna jack before ordering
  • ✗ No dB-per-foot loss figures listed for specific frequencies

Manufacturer description

The GEMEK 36ft N Male to SMA Male coaxial cable connects SMA-equipped gear to N-style antennas, receivers, meters and radio transmitters. That gear includes cellular modems, routers and WiFi signal booster repeaters. Both ends are all-copper, gold plated connectors finished with heat shrink, and the whole run is 50 ohm. The cable is double-shielded KMR240, an LMR240-size coax with a 0.240 inch diameter. Its larger center conductor holds on to more signal over longer runs and at higher frequencies. It is also easy to route: the minimum coiling diameter is 1.5 inches, and GEMEK rates it for…

SpecPicks Verdict

SpecPicks scored GEMEK 36ft 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.

Frequently Asked Questions

Will this cable work with my cellular signal booster or LTE router?

It will if the device has an SMA female port and the antenna has an N female port. GEMEK lists compatibility with SMA-based modems, routers and signal booster repeaters from Cisco, Digi, Cradlepoint, Proxicast, Pepwave, Sierra Wireless and Sixnet/Red Lion.

Is 36 feet too long for a WiFi or cellular antenna run?

It is longer than ideal. GEMEK says LMR240-class cable performs best for WiFi and cellular runs of up to 25-30 feet, so expect some extra loss at 36 feet. For HF/VHF/UHF radio, GEMEK rates it for runs of up to 150 feet.

Can I run this coax cable outdoors?

Yes. The cable is rated for operating temperatures from -40°C to +85°C, and both ends have heat shrink. The listing does not say the connectors are weatherproof, so seal any outdoor joints.

Can I use it with 75 ohm TV or satellite coax equipment?

No. This is a 50 ohm cable with 50 ohm SMA male and N male connectors, made for 50 ohm RF gear such as WiFi, cellular, GPS and two-way radio equipment. Pairing it with 75 ohm gear causes an impedance mismatch.

How tightly can I bend or coil this cable?

GEMEK specifies a minimum coiling diameter of 1.5 inches and rates the cable for 90-degree bends in one inch or less without loss. That lets you route it through tight wall plates and enclosures.
