5.0 out of 5 stars Seems very durable and well built!
Reviewed in the United States on October 28, 2023
Size: 20FTVerified Purchase
I have the Wilson Electronics "WeBoost" cell-signal amplifier for my farmhouse. I wanted to spread the signal to other areas within my house with a splitter and auxiliary interior antennas. BUT, their cables are expensive!

So, I decided to try the MOOKEERF KMR400 Ultra Low Loss Cable with male N-connectors. It feels just as sturdy (stiff) and heavy duty as the Wilson Electronics cables and seems to work just as well for my 50 ohm setup. Therefore, I bought a few more to complete my setup and am VERY PLEASED with the results.

Now, these cables are think and stiff and well shielded. If you have an application where rounding tight corners is necessary, this may be challenging to install. My application was laying them out in my attic and down to a couple of ceilings on other floors, so the stiff cable worked fine for my layout and the shielding protects the signal.

I would highly recommend this product for the quality, functionality, and variety of lengths offered.

Reviewed in the United States on March 12, 2023
Size: 100FTVerified Purchase
I didn’t like the way it’s shipped with a very tight coil and a 90 degree bend at one end by the connector. Other than that the cable is well made, nice connectors. Has held up well to the weather I have about 200 foot lying on the ground in the leaves and mud.

Passed the sweep tests with both nanoVNA and rig expert stick. Also getting really awesome anecdotal performance. Seems to be a pretty legit knock of.

This cable is stiff and I probably wouldn’t try to terminate it myself. But with the various lengths available this shouldn’t be an issue.

I used 2 lines of this coax for my Internet on the 2.5ghz freq in conjunction with 2 sets of yagi average speeds are around 250mg down so it seems that this coax is decent enough for the higher freqs downside is that this is a stiff line I suspect that it's a solid core with is good for losses bad for flexibility so not recommend for antennas on a rotar
