Review: Good Cable - Worked as expected. It was a good quality cable.
Review: Decent stuff! - Using it for a scanner... just strung out of a window, under/around a deck and up to the roof connected to a discone. The end is protected against weather with the pipe mount for the discone. Although I don't remember what my VNA showed when testing the cable I know it tested in the 'good' range. For the price... can't really complain at all!

### ⭐⭐⭐⭐⭐ Solved Bluetooth rearview RV camera problem
*by H***R on January 19, 2021*

I installed a wireless rearview camera on my 26 ft. long travel trailer. The monitor receiver in my truck dash could not get a constant good signal. It would freeze or even totally lose the image. My travel trailer has metal siding which I believe blocked the signal. I used this extension from the camera's antenna connection, ran it under the trailer to the front & connected it to a front mounted antenna. I now have perfect signal. I was worried about signal loss in such a long cable but this is a high quality looking item & it claims to be pure copper and it is fantastic for my use!
