KMR240 SMA Male to SMA Male Coaxial Cable 50 ohm Coax Ultra Low Loss Antenna Extension for 3G/4G/5G/LTE Network Equipment, GPS, RF Radio (3FT 2PCS)

Solid, sturdy, works well, carries signal and dc power. I did add a ferrite bead to help with noise, but I also added some to other components so not sure if it had to do with this cable, but hey maybe you should think about getting some ferrite beads.

This is insulated very well and it appears to be a durable cable.

Tested well with a NanoVNA. It also has the right connectors for solid SMA connections and definitely seemed to improve reception at 1090MHz (for ADS-B) vs cheaper RG-58 coax (which has higher losses at that frequency) where I also had to use PL-259-to-SMA adapters (also causes some loss). Order the length you need, to allow the antenna to be higher, but not too long where again losses would increase.

I use this cable to connect a 1GHz PCB antenna to an SDR for ADS-B. I knew the RG-174 coax I'd been using was of mediocre quality, but I honestly wasn't expecting the improvement I actually got. I don't have a VNA or suchlike to make a serious quantitative test of the cable, but the average maximum range of planes I'm hearing ticked up 22nmi since installing the cable several weeks ago; nothing else with the setup was changed so I have to attribute it to the cable.For the curious, this cable is slightly small in diameter than RG-6 (television cable), and more flexible. Multimeter shows it right at 50 ohms.For a 'serious' installation, there are beefier cables out there. But it's a good upgrade at modest cost to an existing setup, and way better than any cables I've seen which come with an antenna.

I used these to hook up an SDR Play, and they worked well with low insertion loss and are pretty flexible.

Works great and perfect length for the WiFi in my RV

Using with a SDRplayB and a dipole antenna, reception is fantastic, nice heavy cable that seems to be built well.

I had to return this item due to it being too long. YMMV so good luck!
