XRDS -RF 50ft SMA Male to SMA Female Coax Extension Cable, 50 Ohm KMR240 Low Loss SMA Coax Coaxial Cable with SMA Connectors for 3G/4G/5G/LTE/ADS-B/WiFi/RF/Ham/Radio

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. (Amazon 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!

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!

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.

My Flightfeeder was installed in my attic where during the winter it was just fine. As Spring approached, the FF reported high tempatures, I had to relocate it. The existing antenna wire was not long enough, so I ordered this one and it works as good as ever with no apparent signal loss. Shipping was fast and the quality is high.

15 ft length appears to have a -2 to -4db drop in signal strength which is ok for my use case, but may not for others

Good stuff and well made. Great for Satellite

I use this item on my motor vessel and it is needed on the Mississippi River

I bought these cables to move my stock PC Wi-Fi antenna closer to the router (had 4 out of 5 bars). Connecting was easy and was able to move my antenna 10 ft. closer to the router, but the signal strength was worse (1 out of 5 bars) using these extension cables. So, I went back to the stock shorty cables...

J’utilise les câbles pour me permettre de mettre mes antennes de radio contre ma fenêtre. Aucune perte de signal. Très bon achat

Rígido, durable

No problems so far. This works great for ham radio antenna experimentation. I build my own antennas and this works great with a NanoVNA for low loss in the feed line. This coax lets me optimize the lowest SWR on my antenna designs.

Extending the antenna for my SPYPOINT cam allows me to get cell pics from a place I never could before.

Use it in my hamradio equipment without any problems
