About this item

  • Insertion loss of 0.5dB at 100MHz 1.8dB at 1GHz, and 4.6 at 6GHz
  • Simi-flexible coaxial cable with a wide frequency range
  • Termination: Male SMA - female SMA
  • 50Ω input and output impedance with low VSWR (less than 1.6 below 6GHz)
  • Thick plastic cover to protect the cable against harsh conditions such as rain, humidity, snow, dust, and heat
  • Ideal for both outdoor and indoor use
  • Can be used as a transmission line for RF power levels up to 1.7kW at 100MHz and 0.5kW at 1GHz
  • Capable of carrying DC power due to its thick inner conductor


A high-quality RF coaxial cable designed to have a low insertion loss and is suitable for a wide range of RF applications. The 50Ω cable is terminated with an SMA connector (male on one end and female on the other) to provide an effortless way of connecting the cable to existing RF setups and systems. Testing showed low insertion loss at high frequencies with low VSWR. The cable comes with a high-quality material jacket for extra protection.

I would not purchase this product due to the SMA female and comes right off I called and had a second one sent and I did exactly the same thing right after I installed it I would not recommend this product

Bought 4 to extend my waveform 4x4 mimo external antenna for internet. once installed, they work just fine, I was pleasantly surprised by how little the signal degraded. 3 of the 4 are perfectly fine, the other one had the SMA connector just slip off, as if it weren't crimped or secured at all. it went back on but now it can spin, kind of making the SMA useless.I have taped the connections under tension, so it won't really be an issue, but when you are pulling these through a space, the SMA connectors may slip right off.consider replacing their garbage heat shrink tubing with adhesive heat shrink tubing that will bond the SMA connector to the cable.
