## Customer Reviews

### ⭐⭐⭐⭐⭐ I like it
*by J***E on May 9, 2025*

I used this for a run to my rooftop and mount an antenna. It’s not too thick and bends easily. The loss is acceptable and it works great for my ADSB rig. If you’re wanting very minimal loss spent a little more.

### ⭐⭐⭐⭐⭐ Don't notice any signal reduction.
*by P***O on December 11, 2024*

I'm using this cable will a cell phone booster to extend the positioning of the indoor antenna. I don't notice any signal strength reduction when it's in place. The wire is stiff, especially compared to the flimsy wire that comes with my indoor antenna. But that's not a problem for my application.

### ⭐⭐⭐⭐⭐ Working great thus far.
*by J***. on November 30, 2022*

Seem to be excellent quality cables. I'm using them with a Cradlepoint cell modem attached to Wilson UWB 4G LTE 50ohm antennas fastened to long wood "poles" (small diameter white pines I cut down because they looked at me funny), 30 or so ft up in the air. Weather is brutal here, constant wind, with the highest rainfall on the east coast of the US, at around 4k ft on a ridge. I probably should secure the cables to the poles, but they're intended to be only "temporary", though, who am I kidding? They're permanent until they break or fail in some other way.I was ginger with the connectors but they seem strong. Cables are quite stiff and like all previously coiled items want to pretend to be angry snakes forever, but the sheath seems tough and not particularly grabby. Time will tell how they hold up outside, but thus far, I'm happy after a month or so. I have disconnected and reconnected both the SMA and N type connectors numerous times as well without any apparent consequence, however I am cautious and try to be careful when doing so. Regardless, my signal and connection are definitely highly improved, and there appears to be no significantly new interference factor related to the cables, if there is, the improvement in overall signal quality and bandwidth more than make up for it.
