  • Cable diameter: 7/16"
  • N/Male connector diameter: 3/4"
  • Impedence: 50ohms

Signal Loss:

  • The amount of signal attenuation you'll see depends on which frequency you're using. This cable averages approximately 1dB of signal loss. Attenuation for each frequency is below:
    • 700mhz: 0.7dB
    • 800mhz: 0.7dB
    • 1700mhz: 1.1dB
    • 1900mhz: 1.2dB
    • 2100mhz: 1.2dB
    • 2400mhz: 1.3dB
    • 2500mhz: 1.4dB
  • Approximately .5dbm is lost at each connection between 2 cables
  • To prevent excessive signal loss, this cable should NOT be daisy chained with other cables! It is always better to use one longer piece of cable than to screw two shorter cables together.

This is a very stiff, but very well made, high quality, low loss cable. Connectors are high quality, the connector at the wire is covered with heat shrink for protection.

Great cable if you need low loss.

I purchased this product—together with a Cellphone-Mate 3-Watt Verizon 4G LTE Direct Connect Amplifier (CM700V-32) and a Wilson Outdoor Panel Antenna (304453)—to boost the signal of an LG VL600 USB modem that I have connected to a Cradlepoint MBR95 router. I use this setup for my primary internet connection. Before adding these products, the best signal I could manage was about -65 dBm (RSSI) and 10 dB (SINR), which displayed as one bar on the router. After connecting these products, I was able to achieve -32 dBm (RSSI) and 4 dB (SINR), which displayed as a full 4 bars on the router.

This wire is pretty stiff and difficult to work with but I needed to keep signal loss to a minimum. I had the electrician use an existing hole in the brick to route this through to the outside. It works well and I would buy it again.

When trying to determine which cable I needed for my Internet setup, I got help from the people at 3gstore. This cable was the exact one that made my setup work correctly. It works great with the least loss of signal strength, which is exactly what I was looking for. Helpful people, the exact right product at a great price. "Nuff said.

High quality cable. Good connectors. Well made.

Had some fairly stout coax (rg-58 I think) that was left over from an old hughes net set up. Using a yugi antenna we compared these side by side. Can't be 100% sure with the signal fluctuation but we feel we got approximately a -5 signal strength improvement using the low loss cable.
