Review: "QUALITY CABLE" TO INCREASE GARAGE DOOR and/or GATE OPENER's RANGE! - My purpose was to purchase an antenna to extend a 2-button remote's range of my 25-year old LiftMaster® Formula One™ garage door opener. Unfortunately, the cable included with the new antenna was only 10 feet long. (desertcart item #B0CRDMHWSK) So I needed a 5 foot "extension" cable with the c-o-r-r-e-c-t "HIGH frequency" "LOW noise", weather-resistant cable properties, to mount the antenna OUTSIDE of my garage, to achieve the BEST results. (see photos). This extension worked PERFECTLY!! The signal was NOT affected by LED, fluorescent, nor conventional lighting interference inside the garage ... and I tested with all the lighting turned on - individually, and all lights at the same time. Would buy again!
Review: Low loss cable, works great! - I'm using this for my Meshstatic kit and it works great! Very low loss cable and very well made! It is a bit stiff but that's to be expected since it has a solid copper core. I'll be ordering more of this for longer antenna runs. I might even switch to this for my HT's. If you need LOW LOSS coax then this is it!

### ⭐⭐⭐⭐⭐ "QUALITY CABLE" TO INCREASE GARAGE DOOR and/or GATE OPENER's RANGE!

### ⭐⭐⭐⭐⭐ YES IT WORKS!! SiriusXM Antenna Extension Cable
*by A***R on July 13, 2024*

YES, Finally, I needed an extension on my XM Indoor Antenna (25 feet) and tried the ones specifically made as extensions using RG174 cable and I got at most 1 bar of signal on a clear day. After a lot of research I found this extension cable. KRM240 is very low loss and with this cable and a set of adapters (here on amazon 4PCS SMA to SMB) I swapped this for the RG174 extension and now I have 2 bars of signal with heavy cloud cover outside. And it cost about the same. Wish I had found this first.
