Seems like decent stuff. My Rig Expert says the Vf is 0.77. Hmmm. It's also less then flexible. Not an issue for me but for portable use would not be a good fit.

New to this company but great quality product and I can’t say enough about customer service. One of my purchases was here on Amazon and the other from Jefatech website. Didn’t see where I could review the product on their site. Wanted to be sure I left one here. Thanks AJ, top shelf customer service!!!

This is probably my highest quality RG8X cable, and I'll probably utilize it for the most important tasks in ham radio.

This is a good cable and is actually a LL240-FLEX cable, the seller is an American company and has a datasheet for the cable on their website. The connectors are good and there is heat shrink, but I am not sure if it has the waterproofing adhesive or not. I did couple of sweeps for HF and VH/UHF and the loss seems pretty good for the 50ft cable. SWR was below 1.1 all through. It seem in line with the RG8X spec. I will say this cable is little stiff compared to some of my RG8X cable, additional aluminum shield layer may be the reason. Even though their data sheet give a bending radius of 2", I think that's too aggressive for this cable.Overall its very well made nice coax at good price with an American seller to contact and with a datasheet. I will buy from them again.

Cable works great, with no noticed SWR increase. In addition, the ends are not your traditional push through, with a soldered tip. They use a single metal tip, that must be soldered on under the heat shrink! You pay a little more for it, for sure, but worth it depending on your application!

This is nice flexible coax cable and meets spec for LMR240-flex cable, which is very slightly better than RG-8X.I like the white cable, its different than the more common, boring black jackets. It matches a lot of marine-themed applications, but can be used for anything (I am using it for ham radio).The crimped-on PL-259 connectors are attached well, though it would have been nice if the heat shrink on it was color matching. Also, it seems that the heat shrink used doesn't have the water-sealing hot melt glue inside of it which is a bit of a bummer, but not that big of an issue. Its not like PL-259 connectors are waterproof in the first place.Overall, its perfectly fine coaxial cable and I would have no problem buying more if the need arises.

I have always been told to use thicker cable, like RG8U or LMR400. However, since I only needed 50 feet of cable, I wasn't too worried about line loss using this RG8X cable. I connected this cable to a Surecom SWR meter along with my Baofeng K5 Plus radio and a Comet GP6 antenna. Tried on both VHF/UHF (wide range of frequencies) and I get a constant SWR readings of 1.01:1. Can't get any better than this. Radio operators report full quieting and a very strong signal when I transmit.I pinged JEFA Tech support about some items, and they were very quick to respond back to me.Note: There are some SO239 connectors out there that are out of spec. I was originally getting bad SWR readings, and after some experimentation, the SO239 connector was proven to be the culprit. I have a separate Amazon review about this issue with a SO239 connector.Over time, I am curious how this cabling and its shielding will hold up against the freezing temperatures and scorching sun. Will see next year.Overall, this cable works perfect for me. Happy that I am using it.

Happy with this. For 50' it seems like a decent deal. It is flexible enough. The connectors are pretty nice and you can unscrew the threaded female portion and slide it up and down the coax to help you route it places that it won't go without. Seems to work well so far. Pretty standard rg8x.
