I would call this cable a bargain. It's made in China and uses standard RG-174 coaxial cable, which is of course all polyethylene, and typically delivers around 5dB of loss at 10ft at 2.4GHz. If you want to significantly reduce losses, consider using a larger cable such as RG-58. The connectors are typical Chinese RP-SMAs with an unspecified gold plating that usually holds up quite well. Bulkhead bushing with 5/16 nut and lock washer. Both ends of the strain reliefs are heat shrinkable.
